The evaporator is inside the indoor unit, composed of pipes and covered with fins. A device that concentrates a solution or separates crystal grains from a solution by heating. It is mainly composed of heating chamber and evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid to promote the boiling and vaporization of the liquid; the evaporation chamber completely separates the gas and liquid phases. The vapor generated in the heating chamber contains a large amount of liquid foam. After reaching the evaporation chamber with a larger space, these liquids can be separated from the vapor by self-condensation or defoamer.
Four-way valve, a term for hydraulic valve, is a control valve with four ports. The wall-mounted split air conditioner four-way valve is an indispensable part of the refrigeration equipment. Its working principle is that when the solenoid valve coil is in the de-energized state, the pilot spool valve is driven by the right compression spring to move to the left, and the high pressure gas enters the capillary ① Entering the piston chamber at the right end, on the other hand, the gas in the piston chamber at the left end is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move to the left, so that the exhaust pipe is connected to the outdoor wall-mounted split air conditioner, and the other two Connect the pipes to form a refrigeration cycle.
