Cooling System

Refrigeration cycle are used against the card if the cycle, which consists of two isothermal and two adiabatic processes, whose process is as follows: a refrigerant through the compressor adiabatic compression to a higher pressure, the power consumption of the exhaust gas temperature, after the temperature of the refrigerant through the condenser and other places in and around medium heat exchange medium heat to four weeks. After the refrigerant flows through the shutoff valve adiabatic expansion work, when the refrigerant temperature decreases. Finally, the refrigerant passes through the evaporator isothermal heat from high temperature object, the object to be cooled so that the temperature is lowered. This loop again and again to achieve the purpose of cooling.

Energy-saving Design:

In addition to fully consider the safety of refrigeration units, efficient use of all sectors, but while taking multiple energy saving measures: such as: adjusting the cooling capacity of the refrigeration system, liquid-gas bypass regulation, evaporation temperature regulation, low temperature at any point when the thermostat without heat balance, operating power can be reduced to half, so that operating costs and failure rates of the refrigeration system down to a more state of the economy.
Intelligent automatic transfer system expansion, the load automatically adjust the refrigerant flow + intelligent electric power data value (%) to match heating and cooling (load) Analog output data automatically according to the output value. This design than the traditional design saving more than 30%.
