Today we talk about the refrigeration system of three control valves, they are: evaporative pressure control valve, condensing pressure control valve, suction pressure control valve. They can optimize the performance of the refrigeration system, in the refrigeration system these valves are of great significance.
In air-conditioning and refrigeration systems, liquid refrigerants are usually installed in the liquid line, through a transparent wide-angle lens to observe the refrigerant liquid level and flow conditions, through the lens center indicator color changes, check the water content in the refrigerant.
In the air conditioning refrigeration system, the throttle device is one of the four basic components of the compression refrigeration system, which can reduce the high-pressure liquid from the condenser to the low-pressure liquid, and adjust the refrigerant flow into the evaporator.
In the air-conditioning heat pump system, the four-way valve changes the refrigerant flow direction in winter and summer to switch the refrigeration and heating modes of the system.
The throttling mechanism is one of the important parts in the refrigeration device, its function is to reduce the pressure of the saturated liquid (or supercooled liquid) under the condensing pressure in the condenser or the liquid receptacle to the evaporating pressure and the evaporating temperature after throttling, to achieve cooling purposes, adjust the flow of refrigerant into the evaporator to adapt to the evaporator load changes, the common throttling mechanism has the following several.
1. Operation Unit: to often observe the compressor oil surface and back oil and oil cleanliness, found dirty or oil surface drop to be resolved in time, so as not to cause poor lubrication.
