The movement of coolant and the flow of heat when a heat pump is used to cool a building?
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 w…ater 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 (MORE)
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 prescri…bes 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 (MORE)
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.

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.

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. Hea…t 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. (MORE)
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).

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. (MORE)

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 d…efrost 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.

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 f…rom 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 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 p…roduce 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. (MORE)
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 c…ontrolled 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. (MORE)

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!. (MORE)
