Industrial chiller cooling system in the refrigerant process of decomposition: refrigerant in the chiller refrigeration cycle system in the flow of non-stop, its state is also constantly changing, it is in the circulation system at each part of the state are not identical.

1, the refrigerant in the refrigeration compressor changes According to the chiller's refrigeration compressor working principle, the refrigerant vapor from the end of the evaporator into the compressor suction port, it should be in a saturated vapor state, but this is very Difficult to achieve. Because the saturated pressure and saturation temperature of the refrigerant there is a one-to-one relationship, that is, the higher the pressure the higher the temperature, the lower the lower the temperature the lower the temperature. When the refrigerant vapor is compressed into superheated steam in the industrial chiller refrigeration compressor, the pressure is raised from the evaporation pressure to the condensing pressure. But because the compression process is completed in an instant, the refrigerant vapor and the outside world is almost too late to heat exchange, the compression work has been completed, so called adiabatic compression process. Because the compression of the vapor is achieved by the application of energy from the outside, that is, by the external energy of the refrigerant work, which makes the temperature of the refrigerant vapor and then further increase the steam further overheating, that is, the compressor to exclude high vapor temperature At the condensation temperature.

2, the refrigerant in the condenser changes When the superheated steam into the industrial chiller after the condenser, under constant pressure conditions, the first part of the heat emitted, so that the refrigerant superheated steam cooled into saturated steam, it isothermal conditions Continue to release heat and condense to produce saturated liquid. Saturated steam through continuous condensation, saturated liquid will be more and more saturated steam is less and less, and ultimately the refrigerant vapor will be condensed into saturated liquid, then saturated liquid still maintain the condensation pressure and condensation temperature.

3, the refrigerant in the throttling device changes Saturated liquid refrigerant through the chiller in the throat device, from the condensing pressure down to the evaporation pressure. The refrigerant discharged from the outlet of the throttling device becomes about 80% of the liquid and the gas is about 20% of the mixed state. In this case, a small amount of vapor is generated, which is due to the pressure drop of liquid expansion and the emergence of flash gas. The vaporization of the heat is derived from the refrigerant itself, and the outside world almost no heat exchange, it is called adiabatic expansion process.

4, the refrigerant in the evaporator changes in the liquid-based two-phase mixed state of the refrigerant into the evaporator evaporator, the heat absorbed by the heat and continue to vaporize. With the liquid state of the refrigerant in constant pressure isothermal conditions continue to vaporize, making the mixing state of the liquid less and less, more and more steam, all the refrigerant vapor into saturated steam, the re-flow back to the industrial chiller Heart - the suction port of the refrigeration compressor, where it is sucked, compressed, and discharged by the compressor, into the next cycle.
