Abstract

DC60 air conditioning system, which is assembled by a set Condensing external installation This will accommodate a stand-alone built-in cooler (FCU1-5). The condensing unit includes a logic control circuit (33) for control. Refrigerant flow Liquid To fans coils Of the cooling unit in accordance with the requirements For cooling, this system uses a normally open type solenoid valve (LSA-LSE). The system is stuck. Intentionally or unintentionally The fluid path will remain open. Advantageously In order to allow equalization of pressure before the system achieves Get started again, compressors (COMP1, COMP2) will also be installed. The hot gas return device (27, BS1; 26; BS2) when the number of cooling units In use, the number is much lower for the compressor capacity, the liquid refrigerant will be impeded to reach the compressor by delivery. The hot gas portion is released by the compressor to the inlet. In order to cause the load With the compressor Air conditioning system, which will be assembled with a set Condensing external installation This will accommodate a stand-alone built-in cooler (FCU1-5).
