Can you install a heat exchanger on an existing heat pump that will allow you to heat your pool while cooling your home?

Yes, you can, but you will probably have to design and fabricate it yourself as I am not aware of any commercially available kits to help you accomplish this task. What you are asking for is not unreasonable. It makes perfect sense to use the heat that is extracted from your house to heat the pool water rather than just exhaust it to the outside air. However, only recently have the major HVAC manufacturers started thinking about their systems in an integrated fashion, i.e. figuring out ways to move heat from the places its not wanted to the places where its needed ALL WITHIN ONE SYSTEM. At this point in time, there is no real standardization of heat pump components that would allow you to simply and easily take the heat from the heat pump and transfer it to another heat exchanger to warm the pool water because there are so many different types of heat pumps that have been manufactured over the past 20-40 years. Thus, even if someone did develop a kit of this sort, it would still require some kind of custom-built piping and control mechanism to interface with all of the different manufacturers and models of heat pumps that are out there in the world. Hope this helps ... from Jalex137: It's an interesting idea, but I wonder if it's practical. It seems to me that during the season that you would be cooling your house, you wouldn't need to be heating the pool. from Uncledunc: the reason you heat the pool water in the summer is the difference in the temperature between the air and pool water. On a 75 degree day, your pool water at 67-68 degrees fees fine. But if tomorrow the afternoon temperature shoots up to 90 you turn blue and FREEZE. Living in So-Cal tells one all he needs to know about heating the pool (often with solar covers during the day, plus the heater) to enjoy swimming on hot summer (and Fall) days. Keeping the air to water temperature within about 10 degrees (max) is ideal, from my experience with 4 in-ground pools. My father-in-law attempted the AC heats pool water trick back in the late '60's but the contraption he came up with had no controls - just a big water tank with SS piping for the Freon gas. Later he attempted to upgrade the idea with a switching mechanism to route the refrigerant to the normal condensing coils when the pool water was already hot enough. Bottom line - the hardest part is sizing the heat exchanger to the thermal load of the house (cu. ft. / not sq. ft.) and the gallonage of the pool for your typical summer ambient temperature (and nighttime temperature swings) in your local. There is no "1-size-fits-all" answer. And it takes some decent thermodynamic engineering to get it right. IMHO, the concept is feasible, but the trick is to over-size the heat exchanger and then TRY to locate a suppler of a high pressure switch to shut off the pool's heat exchanger. Otherwise you run the risk of have your pool turn into a sauna/spa... which some folks might actually prefer! But, if nothing else, in northern climates you'll get a longer swimming season without turning on the heater. Hope this adds to the discussion. - Uncledunc

Is there a optimal flow rate for maximum heat transfer when using a heat pump?

Answer . \nYes there is an optimum flow rate. Kind of! The heat pump manufacturer will post on the internet or in the users guide what the maximum and mimimum flow rate through his heat pump should be. I take it that the optimum then, is anywhere within that range. My pump manufacturer prescribes 20 GPM to 70 GPM for the heat pump I will be using. Too low a flow causes the heat pump to overheat. Too high a flow is hard on system components.\ndburr

Can you use a ground loop small pump and heat exchanger in the air handler to cool your house?

sounds good. ground loops work and there are sites on the web showing how to and such. > I wanted to put a car radiator in a friends cabin and another in the river out back. A small pump and plastic piping would have done a number on the hot weather. He opted for a large window unit.

No heat in your Chevy c-1500 you have replaced the heater core the thermostat water pump and have enough coolant in the system but still no heat?

Answer . Check the heater valve and/or the controls to the valve.. Answer . \nmaybe a problem with the controls, most of them are run off of vacuum, if a hose has a hole in it, it wont work

Can a heat pump thermostat be used on non heat pump air conditioning system?

yes it can but everytime you want heat you have to put it on Emergency Heat..

What is a heat pump?

A heat pump is a heating system that applies the principle of refrigeraation to heating homes. These principles are: 1. when a gas is quickly compressed, it's temperature rises; 2. when a gas is allowed to expand suddenly it's temperature fallls; 3. when a liquid evaporates, it absorbs heat; and 4. when a gas condenses it releases heat.

How does an absorption chiller generate coolth from heat is it simply heat is used to generate the compression in the cooling cycle rather then a pump?

The heat is used to regenerate the lithium bromide back to being very salty whereat it will absorb moisture from the cooling medium and make it cooler.. Too simple an answer - granted.. Fred Calhoun PE

What does heat flow from?

Heat Transfer is the study of how heat flows through objects. Any object that has temperature wants to dissipate it into surrounding objects and to colder objects. If the surrounding objects or air is at the same temperature, then heat will not flow. Some materials conduct heat more than others. Heat can be transferred into flowing gases and air.. There is no such thing as cold flow. Rather it the flow of heat such that it cools one area and moves it to another area where it is dissipated.

What is the sequence of events that causes the movement of the plates on the earth's surface using the terms core heat mantle flow rise sideways drags cools sinks?

This may not use all the words but this is right. The magma in the core is heated and rises. After that it flows side ways. Then it sinks

Why low temp rise in cooling mode of heat pump?

COULD BE MANY THINGS- NEED MORE SPECIFICS. MOST LIKELY TXV OR CHARGE ISSUE. IF TEMP RISE GOOD IN H/P MODE W/O STRIP OR SUPP. HEAT ADDED MOST LIKELY TXV. IS OA TEMP AN ISSUE THIS TIME OF YEAR? (LOW HEAD PRESSURE). lc

Explain the sequence of events that cause the movement of the plates on the earths surface use these terms core heat mantle flow rise sideways drag cools sinks?

Magma gets heated, rises, flows horizontally (the plate over it moves with it, but not as fast as the magma), cools and sinks..

Explain how a heat pump is used to both heat and cool a building?

a heat pump contains a water filled loop of pipe that is buried toa depth where the temperature is nearly constant

What is heat pump?

A Heat pump is a air conditioning/heating system that utilizes a reversing valve in the refrigerant circut that reverses the flow, and brings the heat in side the home from outdoors

Geothermal pumps can be used for heating but not cooling?

false They are used for both. true, they can be used for either one. thanks for making me miss the question dip sh*t FALSE....^^^THANKS FOR MAKING ME MISS THE QUIETION DIP SHÏT

Geothermal pumps can be used for heating or cooling?

Geothermal (ground source) heating systems are a very rapidly growing technology in the residential / commercial heating and cooling market. Even though it does cost a little bit more in the beginning to install rather than traditional HVAC system it repays itself quickly because of its low maintenance cost. Ground source heat pumps can be applied to a wide range of both domestic and commercial applications, ranging from heating a small residential property with a swimming pool to heating and cooling a large commercial building like a hotel. True

What controls the heat pump to determine whether it is in the heating cycle or the cooling cycle?

what controls the heat pump to determine whether it is in theheating cycle or cooling cycle

How Does Heating From A Heat Pump Work?

The heart of the heat pump is the Copeland scroll compressor. The compressor continuously pumps the ozone safe refrigerant from the outside coils to the inside coils. The refrigerant carries the heat with it to be released inside the house. Then the warm air is circulated throughout the home by the furnace fan. In the summer the flow of the refrigerant reverses and the house is cooled in the same way. The scroll compressors are extremely reliable and virtually trouble free. Copeland is the largest manufacturer of heat pump compressors in the United States. Our Goodman heat pumps are built to last with reliable Copeland scroll compressors. Scroll compressors are very durable because they have fewer parts than the older reciprocating compressors and are also simpler in construction. Instead of pistons and valves which the older compressors had, the scroll compressor has a scroll that orbits to compress the refrigerant.

Can you use a heat pump in central Wisconsin?

Yes, as part of a Dual Fuel system. If your electric rates are more favorable than fossil fuel rates.

Can you use pex tubing in a high rise building on the heating and cooling system?

The answer is: it depends. Local codes in metro areas might restrict you from doing that, so its best to check with a building official in your area first.

Describe the direction of heat flow when a warm object and a cool object touch?

The flow of heat energy from the warmerobject to the cooler one is so probable that it is considered a law in thermodynamics.

When do i use heat pump to heat inground pool?

A heat pump can be used all year round. They extract heat from the air even in cold weather.

Heat pump with heat on for about an hour then cool air comes on. Why?

well im a hcac student and from what i know from heat pumps if its cold out side and you turn ur heatpump to heat it sends the cold air out side. if it runs too long the outside coil will start to freeze over, there is a thermometer out side that notices this change and will send the system into a defrost cycle, which all that is is the reversing valve slide kicks over and reverces the flow of frion which sends the heat to the outside coil to dethaw the outside coil. while this is happening the air coming out of the registers will blow cold air, this is when ur augzilery heat which is ur 1rs bank of heat in ur air handiler turns on so you don't have cold air coming out of ur registers. hope this helps. from what it sounds like ur system is going into defrost cycle and ur augzilery heat isn't coming on.

What size house can a heat pump with a 3.5 ton compress heat and cool?

You should have an HVAC company perform a Manual J load calculation done on your home. for the best sizing . The old way here in the south USA dictates 3.5 tons cooling served most homes from 1500-1700 sq ft. depending on variables. BE CERTAIN get the Manual J calc. for best results. Tom H. ,HVAC professional, New Orleans.

Why is a heat pump able to heat and cool the same building?

A heat pump is an air conditioner working in reverse. When the unit is in cooling mode, it moves heat from the interior to the exterior. When the unit is in heat mode, it moves heat from the exterior to the interior. In most cases, the thermostat controls the necessary components that perform the reversing process necessary to change from heating mode to cooling mode.

Explain the sequence of events that cause the movement of the plates on the earths surface use these terms core heat mantle flow rise sideways drag cools?

First the heat below the mantle makes even the solid part of themantle flow very slowly as though it were very thick liquid. thehot rising part of the mantle cools as it nears the crust. as thecooling mantle moves sideways it drags along the plate floating ontop of it. the arrows show the cooled mantle sinking back down.later on the mantle will may be get warm and rise again.

I have Ceiling hung Florida heat pump unit. when i call for cooling I get heat from vents?

The O and B terminals are not properly enabled in the thermostat or not correctly hooked up in the unit. Some units energize the O or the B terminals to activate the reversing valve for heating or cooling, Check with the manufacturer or just try to make the swap and see if it corrects the problem.

The what law of thermodynamics states it is impossible for heat to flow from a cool object to a warmer object?

The second law of thermodynamics states "energy systems have a tendency to increase their entropy rather than decrease it." This can also be stated as "heat can spontaneously flow from a higher-temperature region to a lower-temperature region, but not the other way around." Heat can appear to flow from cold to hot, for example, when a warm object is cooled in a refrigerator, but the transfer of energy is still from hot to cold. The heat from the object warms the surrounding air, which in turn heats and expands the refrigerant. The refrigerant is then compressed, expending electrical energy. so the second law of thermodynamics is your answer I believe.... there are 3 proper laws of thermodynamics with a possible fourth, fifth and sixth still being postulated.

What component allows a heat pump to switch between heating and cooling modes of operation?

Condensers with a heat pump option have a Reversing Valve. They seldom need replacing, but in the event that they are bad... they are very difficult to braise in the system.

Should you use the heat pump in the winter?

Heat pumps are much more efficient than they used to be. For example a 3 ton 13 SEER heat pump today can generate 22,000 btu's of heat even at 32 degrees. Compare that with heat pumps 15 - 20 years ago where you were lucky to get 10,000 btu's at the same temperature. So yes, run your heat pump all winter.

What units are used to measure heat flow?

BTU/hr . A British Thermal Unit is: 1. The quantity of heat required to raise the temperature of one pound of water from 60° to 61°F at a constant pressure of one atmosphere.. 2. The quantity of heat equal to 1 / 180 of the heat required to raise the temperature of one pound of water from 32° to 212°F at a constant pressure of one atmosphere..

What are heat pumps used for?

A heat pump is a central air conditioner that uses a reversing switch to operate in reverse; the way the air conditioner works in the summer. If you went to the big fan unit (condenser) outside your house during the summer, you would notice, it blows hot air from the fan . Heat pumps are used to produce heat for residential housing, economically, by absorbing temperate winter air, and using it to heat your house. Heat pumps can usually maintain heat in your house down to about 20 degrees Fahrenheit, until you would need to use another source to heat your house. Heat pumps are mostly used in the Southern parts of the United States, where the winters are mild, Heat pumps can be economically used in other parts of the United States where average temperature during the winter may not go below the 20 degrees, disused earlier, and the break-over price for fuel cost using the main furnace. Usually, propane gas, verses running the electricity for the heat pump is more economical. To find out if a heat pump would work for your situation. Contact a qualified hvac contractor to perform an energy survey of your residence.

How does a heat pump use freon to heat?

A valve is used to reverse the flow of freon. In the heat mode, the high or hot side gas is pumped to the indoor unit, The low or cold side is pumped to the outdoor unit. The valve is reversed for the cool mode. Pumping cool gas to the indoor unit and hot gas to the outdoor unit.

Which type of heat exchanger is used for cooling?

There are some special rules associated with heat transfer . The first is there is no such thing as cooling, .. removal of heat is a relative cooling process from the initial temperature's difference of beginning and ending temp is the relative change. the second is rigidity in expansion ...If not controlled the process can create failures in post stress reactions . (after it is heating up).. the third is coefficient of utilizati on ..based on area material and temp differential After going through all that the best cooling cooling/heating exchanger is one that gives optimal radiation through utilization of air flow within the limits of the temperature applied. A special design for every application is generally applied in an engineering application. Air conditioning systems have opted for two basic styles the slanted multipass and the A-coil both are implied surface area improver's.

Why buy a heat pump to cool your home?

Heat pumps are an economical way to provide clean heating AND cooling of a home.

How do you build a tree house with heating and cooling?

The easiest way to build a tree house with heating and cooling, is to build the tree house completely sealed, (By building the structure really tightly and then coating it with something that's air proof.) and then get the tree-house access to electricity and an air-conditioner. If you cannot do that, than build it in a high place and keep it shut in the winter and open in the summer.

What is an air heat pump used for?

An air heat pump is used to heat and cool your home. It is like an air conditioner in the warmer months but then can also heat your home if the outside temperature is above freezing.

What component allows a heat pump to switch between heat and cool?

the reversing valve is what actually changes the refrigeration cycle from heat to cool. the reversing valve receives its signal from the thermostat.

Why sea water not to be used as coolant in heat exchanger?

because sea water contains large amount of salt in it as impurity. this has much effect on its thermodynamic properties as compared to normal water.

What must be done when you have ice build up on the heat pump?

either the sensor or the defrost board is bad or the system is low on refrigerant

Why won't heat pump cool?

i set my thermostat to cool, my heat pump start it go to heat but not cool, i think the thermostat. can u help.

How heat pump used to heat the building?

Imagine a window AC unit installed backwards, rejecting heat indoors while air conditioning the world, this is a heat pumps heat mode. As the unit is air conditioning in the cool outdoors eventually the outdoor coil will ice up requiring a defrost cycle, defrost is the AC mode except the outdoor fans off to assist with the defrosting. A defrost cycle is time and temperature initiated, time or temperature terminated.

Where in the house is a heat pump used?

A heat pump is often used in air conditioning units and refrigerators because a heat pump is used to transfer heat from one place to another. Often heat pumps are used to remove heat from a building

What controls the heat pump to determine whether it in the heating cycle or cooling cycle?

The refrigerant is pumped round the system, one way or the other. The warm side is the high-pressure side on one side of the nozzle.

What are the uses of a ductless heat pump?

Ductless heat pumps operate in the same way as regular heat pumps. However it is easier to install for quality heating and cooling that works quietly with no extra noise.

Can you pump down a heat pump system in heat mode just as you would do in the cool mode?

No, the energy in a heat pump system must be transfered to anotherheat pump system because the first law of thermodynamics say thatenergy cannot be created nor destroyed

What makes of fan can be used for cooling and heating?

The most notable fan used for both heating and cooling would probably be of the Dyson brand. They have a product called the Dyson Hot+Cold, which is a bladeless heater fan used for both cooling and heating.

Is it easier to heat and cool round buildings?

Haeting and cooling round buildings depends on the system and howit performs. Heating and cooling systems are not any easier toinstall in round buildings but are able to keep the environmentcool or warm.

Do heating and cooling chillers use freon?

"Freon" is a trademark name of the the DuPont Corporation for aseries of CFC and HFC refrigerants manufactured and marketed bythem - thus, it's only actually Freon if it's manufactured by themand marketed by that name. They all use some form of refrigerant, but not all of them use CFCor HFC refrigerants. There are refrigeration units which usestraight ammonia, for example.

What material is heated up and cooled down causing density changes and movement of material?

I suspect the right answer would be a fluid: liquid or gas. Wateris simply an example. The question is so tangles it's not easy tounderstand what its writer wishes to know, but appears to citeconvection currents.

Should a heat pump cool below 59 degrees?

A heat pump generally has a max temperature change of 20 degrees F.If air entering the return duct is 90, it will not be cooler than70 on the discharge side, Below 60, it is working against theinsulation and air infiltration into the house. It is an airconditioner, not a deep freeze. Remember that a heat pump eitherdumps heat outside to cool a house, or picks up heat from outsideto heat the house. If it is 100 degrees outside, it is hard to dumpheat. Below 35, it is hard to pick up heat. At an outside temp of59 degrees, it should work for either- but nobody needs coolingwhen it is 59 degrees outside. Open a window, already!.
