Common Pressure Valves and Protection Devices of Refrigeration Units

Evaporative pressure regulating valve is generally used in a refrigeration compressor which is responsible for both high temperature cold storage and low temperature cold storage.  Evaporative pressure regulating valve is generally installed on the evaporator outlet pipe of high and low temperature cold storage to maintain the stability of evaporative pressure in evaporator of different temperature and working pressure in the system. Evaporative pressure regulating valve is divided into direct action type and control type.

The Functions And Matching of Air Source Heat Pump Buffer Tank

A heat pump is an energy-saving device that uses high-level energy to flow heat from a low-level heat source to a high-level heat source. As the low-level heat source of the heat pump, air is inexhaustible. It is available everywhere and can be obtained free of charge. Moreover, the installation and use of air source heat pumps are relatively convenient. Buffer tank is very important to keep air source heat pump working efficiency, Eurostars engineer shares some knowledge about buffer tank of heat pump.

What Should We Pay Aattention to When Building Cold Storage In the Basement？

In the construction of cold storage in the basement, first of all, there is no ventilation in all sides of the cold storage body insulation, and there is no outside hot summer sunlight and cold winter cold invasion. However, the basement is surrounded by either cement wall carrier or soil wall carrier. To build cold storage, it is necessary to do heat preservation around the carrier, otherwise the cold air will penetrate into the wall or underground.
