Cooling plant PROVIDED BY HEINEN & HOPMAN

cooling plant A cooling plant belongs to the main units of an air conditioning system. Without a cooling plant it will be impossible to meet a comfort inside climate when cooling is needed. A cooling plant consist of four main components “Compressor, condenser, expansion valve and evaporator”. The diagram below shows the complete cooling circuit with all the main component as well the phase of the refrigerant in each stage of the circuit. Compressor The compressor is a mechanical device that increase the pressure of the refrigerant gas by reducing the volume. There are four kind of compressors:...

Condenser A condenser is a heat exchanger that extract the heat of the compressed refrigerant by transferring it to a cooling medium (air/ water). In the condenser the refrigerant transforms from its vapor to its liquid state. The expansion valve controls the amount of the refrigerant that flow into the evaporator. There are two kind of expansion valve: There are two different groups of condensers: • Air cooled condenser • Water cooled condenser The orifice within the valve does not remove heat, but only reduces pres-sure. Heat molecules contained in the liquid refrigerant are thus allowed to...
