REFRIGERATION SYSTEM FOR TELECOMMUNICATION CHAMBER REGULATING REFRIGERANT CHARGING AMOUNTS ACCORDING TO ATMOSPHERE TEMPERATURE

摘要

The present invention is a communication relay base station cooling system having a refrigerant circulation environment passage sequentially passing through a compressor, a condenser, an expansion device, and an evaporator, and having a receiver between the condenser and the expansion device to cool the interior of the communication relay base station. A receiver inlet pipe connecting the condenser and the receiver to introduce refrigerant from the condenser to the receiver; A receiver outlet pipe connecting the receiver and the expansion device to outflow the refrigerant to the expansion device; First, second, and third valves installed at the receiver inlet tube, the receiver outlet tube, and the first bypass tube to open and close the valves; And it characterized in that it comprises a control device for sending an opening and closing signal to each of the first, second and third valve. By this configuration, the coolant flows to the first bypass pipe by closing the first and second valves in the summer and opening the third valve. In winter, the third valve is closed and the first and second valves are opened. By allowing the refrigerant to flow through the air conditioner, it is possible to optimize the cooling system by adjusting the required amount of refrigerant charge in accordance with the change of the ambient temperature.;Communication relay base station, air conditioning system, four season cooling, receiver, bypass pipe
