Typical evaporator temperature in an air conditioning system is?
40-45 depending on load
Why would the rear air conditioning in a car blow hot while the front blows cold?
The most typical problem is the expansion valve for the rear is bad. another possibilty would be the evaporator in the rear is clogged up but that's not common.
How much refrigerant 2001 jaguar s?
Approximately 2-3 lb. for a full charge, starting from scratch. (This is a typical figure for most automotive air conditioning systems, to estimate how much refrigerant you need on hand.)
What are typical evaporator tubes made of?
Copper
What is the direct expansion valveand how does it work in the system what are the different between the direct expansion valve and the indirect expansion valve?
A direct expansion valve, sometimes called a DX valve, modulates the amount of refrigerant fluid, entering as a liquid, allowed into a heat exchanger. Past the DX valve the pressure is much lower and a warmer fluid on the other side of the piping in a heat exchanger boils the refrigerant fluid into its gas, absorbing heat and cooling the warmer fluid. Most commonly one sees this on a household air conditioning system where the warmer fluid being cooled is air from the house, which will then be sent back into the house to cool it. The DX valve modulates the amount of liquid refrigerant let in to cool the air and assure that the refrigerant is all boiled off by the time it leaves the cooling coil. If it were not all boiled into a gas, liquid could reach the refrigerant compressor, the next step in the refrigerant gasses circulation loop. Liquid is very difficult to compress and it would (and sometimes does) break the compressor when either the DX valve has not worked correctly or there has been some other technical malfunction. There is no "indirect expansion valve" to contrast to the direct one. Instead the "direct" adjective distinguishes the direct cooling of the air by the expanding, boiling refrigerant from the more typical secondary fluid, usually water, used in larger systems to cool the air indirectly. "Indirectly" because water is not the primary source of cooling, the boiling refrigerant is; it cooled the water first.
How much freon is in a ten-ton air conditioner?
The amount of freon in an air conditioning system is more dependant on the size of the components and the type of equipment than the cooling capacity. A typical system has a tag located near the charge ports that will tell you not only how much refrigerant is in the system, but what type as well.
In a typical classical conditioning experiment a neutral stimulus is?
Something that doesnt start the response by itself.
What is typical of college football conditioning?
makes us all work better, faster, stronger .
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 is a packaged HVAC?
Usually a package HVAC or Package unit is one large unit that has the evaporator and condenser in the same location unlike a typical system where the evaporator and condenser are located in separate locations. Package units are usually used for commercial building and placed on rooftops.
Define a zeotropic refrigerant blend and give an example?
In a zeotropic blend, the blends boil out at different temperature but at the same pressure. typical example is R704
What happens when you have a bad air conditioner compressor?
A Typical Air Compressor used in an air conditioning system is used to compress the vapor refrigerant to a higher pressure. If your compressor is not good enough to compress to the required pressure then your air con. will not provide a good cooling effect. P.S. : The temperature when changed on the main panel will directly change the pressure of your compressor which will affect the room temperature.
