The difference between the three types of evaporators dry, flooded, and falling film evaporators

The refrigerant in the dry evaporator passes through the heat exchange tube, and the cold water runs outside the high-efficiency heat exchange tube. Such a heat exchanger has relatively low heat exchange efficiency,

Hitachi heat pump compressor

Does the compressor not start related to the four-way valve? There is no relationship between the compressor does not start and the four-way valve. Therefore, when the four-way valve coil is damaged, it will not cause the air-conditioning compressor to fail to start normally, nor will the compressor start normally after the good four-way valve coil is replaced.

Hitachi water source heat pump compressor

How does the air conditioning compressor work? The air-conditioning compressor is also called a rotary (rotor) compressor, and its working principle is to rely on an eccentric rotor under the action of spring force, the compressor, and the eccentric rotor are always in contact with the container separated by the sliding container Changes to achieve a process of compression. When the eccentric rotor rotates, the volume of the container changes and the gas is compressed.
