What is suction and discharge head?
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.
What is an anomaly based system?
Anomaly-Based systems define normal activities in term of network traffic and system resource usage so that any deviation from the defined baseline is consider an attack. anomaly-based systems are typically rolled out with the learning period in which all relevant parameters are analyzed.
What is a swamp cooler?
a device that cools air through the evaporation of water.Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles.They are not as efficient as real ac's. They use air blown across water to cool vs refrigerant. They work but much less cooling power.
What are the advantages and disadvantages of osmosis?
AdvantagesReverse osmosis systems have plenty of advantages. They are friendly to the environment, as they do not produce or use any harmful chemicals during the process. These systems also require a minimal amount of power. Reverse osmosis systems work well in home filtration systems because they are typically small in size.Taste of the purified water is another distinct advantage. Reverse osmosis removes dissolved minerals and other contaminants that cause water to smell unpleasant, taste poorly and take on unusual colors.Removal of dissolved minerals, metals and other particles benefits plumbing systems. There is nothing in the water to corrode pipes or collect as sediment.DisadvantagesReverse osmosis treatments require an enormous amount of water. Such systems typically return as little as 5 to 15 percent of the water pushed through the system, which means it also takes a long time to properly treat the water. What's left then exits the system as wastewater. This amount of wastewater can burden home septic systems. Water entering the reverse osmosis system should also be free of bacteria. While reverse osmosis systems do remove nearly all microorganisms, the risk of contamination through tiny leaks or deteriorating parts prevents reverse osmosis systems from being used to remove bacteria.
What are some good examples of incontrovertible systems?
There are several good examples of incontrovertible systems. A good examples of incontrovertible systems should be camera systems, or recorded systems.
A refrigerant systems evaporator typically runs about how many degrees of superheat?
10 degrees
Excess superheat in a capillary tube system means that there is?
excess superheat in a capillary tube systems means that there is ______ charge
Is there a difference between evaporator coils and cooling coils in air conditioner unit?
usually both the same thing just different names. Most hydronic (water) systems are referred to as cooling coil and heating coil. Direct refrigerant system is an evaporator coil. Also depends on who your talking to.
What is the principle of air conditioning?
Evaporation is the primary principle. The three primary components of most residential air conditioners are: # Compressor # Condenser # Evaporator As the refrigerant is compressed in the compressor, lowering the temperatures required to change from liquid to gas and gas to liquid. This is an exothermic, or heat generating, process. The compressed refrigerant, still under pressure, passes through the condenser. For residential systems, this is the "fan in a box" part of the air conditioning system outside. The condenser is actually blowing heat away from the refrigerant. Because the refrigerant is pressurized, the temperature is low enough for the refrigerant to turn liquid. The evaporator is where the cooling actually happens. When the pressure is reduced, the refrigerant evaporates; it turns from liquid to gas. Evaporation is an endothermic, or heat absorbing, process. The refrigerant absorbs heat from the air around it. This leaves the air around the evaporator much cooler and ready to be blown into the house. (Most refrigerators operate using the same process.)
Why is a capillary tube thought of as a dry-type?
The Capillary tube metering device is used primarily on small fractional-horsepower refrigeration systems that have relatively constant evaporator heat loads. These systems are hermetically sealed, leak free systems with dry-type evaporators that use a minimum of refrigerant. The capillary tube metering device is a fixed bore device, itcontrols refrigerant flow by pressure drop.
Is odorant added to refrigerant in home AC systems?
No
What is indirect refrigeration system?
Indirect and direct refrigeration systems are typically used on LPG carriers for cooling different cargos. Indirect systems cool the cargo by a refrigerant without being compressed. In the direct refrigeration cycle the cargo is compressed, condensed and returned to the tanks. The safer method is indirect refrigeration because the cargo never mixes with the refrigerant.
What of the following statements is not true about newer mobile AC systems Many of these systems contain less refrigerant than older systems Too little refrigerant in AC system can cause problems It's?
Which of the following statements is NOT true about newer mobile A/C systems?
What does work Air condition in car?
I am going to take the liberty of guessing you mean, How does the air conditioning (A/C) in cars work? CAUTION Do Not try and repair your own A/C system unless you have had special training in A/C repair. A/C systems are under high pressure and can be extremely cold or hot. The air conditioner in your car is made up of five major components; the condenser, the compressor, the evaporator dryer, the evaporator, and a thermal switch. When you turn the A/C on you here a loud click form under the hood and hear you engine bog down., that is your compressor turning on. As the name suggests this compresses the refrigerant in the A/C system ( either you have R-12 or R134a). From the compressor the refrigerant is moved to the condenser. The condenser is located in front of the radiator to get the most cooling power. *side note* during the summer when it is hot, if you are using your A/C on a hot day and your car begins to over heat turn off your A/C , the A/C system puts extra heat into the radiator. The condenser turns the gas form of the refrigerant cools it down and turns it into a liquid. It then goes to the thermal switch. The thermal switch controls how much refrigerant to put out to the system and also controls the compressor cycle. At this point the cold refrigerant goes to the evaporator. The evaporator is located in your dash. it is the HVAC (Heating Ventilation and Air Conditioning) box, which is also where the heat comes from. When you have your A/C on the HVAC takes air from the inside of the vehicle and runs it over the evaporator. Since the refrigerant is cold the the cold air molecules switch with the warm air molecules lowering the temperature of the air. During the temperature change the evaporator also attracts moisture and dust, which is why the A/C is always dry air and has a different smell. At this point the refrigerant is very hot and has evaporated into a gas form again. The hot gas then goes to the evaporator dryer. As the name suggests this gets the moisture the refrigerant may have picked up inside the car, moisture damages the compressor. from here the refrigerant goes back to the compressor and the process starts over.
What is an air conditioning evaporator coil?
This is a assembly of a coil of copper or alumnium tubing and fins inside the house heater unit that cools down for the furnance blower to send cold air to the living spaces.
How do you fix a plugged evaporator on a 2002 Honda odssey?
You can flush the evaporator out, or replace it. Both will require specialty knowledge in repairing air conditioning systems. Take your can in to a professional to have it fixed.

Most systems using R-134a as a refrigerant.
