Air conditioning refrigeration cycle diagram. The metering device component 3 on this refrigeration cycle diagram is the dividing point between the high pressure and low pressure sides of the system and is designed to maintain a specific rate of flow of refrigerant into the low side of the system. Gases give off heat when changed from gas to liquid. It purposes is to reject both sensible and latent heat of vapor absorb by the air conditioner units. Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump air conditioning and refrigeration systems.
The air conditioning compressor is known as the heart of the central air conditioning units. The refrigeration cyclein this refrigeration cycle diagram the air conditioner condenser is air cooled condenser. The air conditioner evaporator is locate between points six and one in the basic refrigeration cycle diagram. It functions the same way as the evaporator but it does the opposite.
Its one of the divided points between high and low side. When the hot refrigerant vapor discharged from the compressor travels through the condenser the cool air flowing through the condenser coil absorbs enough heat from the vapor to cause it to condense. For this reason all air conditioners use the same cycle of compression condensation expansion and evaporation in a closed circuit. Chiller plant and how it work httpsyout.
The above diagram depicts a simple air conditioner. Liquids absorb heat when changed from liquid to gas. How an air conditioner works. Air conditioner parts 2 air conditioner compressors.
A heat pump is a mechanical system that allows for the transmission of heat from one location the source at a lower temperature to another location the sink or heat sink at a higher temperature. The evaporator is a heat exchange that is responsible for absorbing heat from whatever place medium that needs to be cooled. As we can see in the refrigeration cycle diagram. If the wrong capacity of metering device is used or if there is a problem with the metering device an incorrect quantity of refrigerant.
For our discussion its indoor. For an air conditioning system to operate with economy the refrigerant must be used repeatedly. Most air cooled air conditioning and refrigeration systems are designed so that the refrigerant will condense at a temperature about 25 to 30 degrees above outside ambient air temperature. The condenser units are located outdoor with the compressor.
Inside an air conditioning system is a chemical refrigerant which is a compound that easily changes states from liquid to vapor and back again.
