EVR10 Series 1/2'' Solenoid Valve in Refrigeration
EVR10 Series 1/2'' Solenoid Valve in Refrigeration is a direct acting structure. When the coil is energized, a magnetic field is formed to generate magnetic force and pull up the iron core. The small valve orifice of the piston is opened to discharge the pressure on the upper part of the piston. Under the action of pressure difference, the piston is pushed up and the main valve orifice is opened to form a path. Cut off the power supply, the iron core loses its magnetic force and automatically resets under the action of the spring and falls down. Close the small valve mouth of the piston. Pressure is formed on the top of the piston, which prompts the piston to press down and cut off the pipe.

EVR10-012S Solenoid valve in refrigeration system ((Ice machines):
Working principle of industrial chiller with EVR10-012S:
The industry commonly known as refrigerators, refrigerators, chillers, chillers, chillers, etc., as in various industries widely used, so the name is also numerous. The basic principle is a multifunctional machine, through compression or heat absorption refrigeration cycle to remove liquid vapor. The steam compression refrigerating machine is composed of four parts: a steam compression refrigeration cycle compressor, an evaporator, a condenser and a partial metering device for realizing different refrigerants. Absorption refrigerator USES water as refrigerant and relies on water and lithium bromide solution to achieve strong refrigeration affinity.
The working principle of the refrigerating machine is steam compression refrigeration, that is, using the principle of heat absorption when liquid refrigerant evaporates and heat release when steam condenses. In refrigeration, evaporation is the process by which a liquid refrigerant boils into a gaseous state. When you go from a liquid to a gas, you have to absorb heat from the outside. So this is an endothermic process. The temperature at which the liquid refrigerant evaporates is called the evaporation temperature. Condensation is the process of turning steam into liquid by cooling it to a temperature equal to or below saturation.
Technical and economic comparison of water cooling and air cooling units:
Given the large number of air cooled condensers in refrigeration units, it is usually difficult to arrange. On the other hand, too small water cooling units are not suitable for use, so for medium size air cooling units, the same amount of cooling. Water - cooled refrigeration units are compared.
Now compare a certain type of water-cooled refrigerating unit with the same air-cooled refrigerating unit, main engine and evaporator:The annual running time of the compressor is from 1000 hours to 3000 hours, and the annual running time of the cooling tower and the pump is from 1400 hours to 4200 hours.
