reasons why the constant temperature and humidity test chamber does not cool

1. Introduction The phenomenon that liquid refrigerant and/or lubricating oil damage the suction valve plate when the gas is sucked into the cylinder of the compressor, and it is produced when the piston is compressed when the piston is close to the top dead center and is not quickly discharged during the exhaust process after entering the cylinder.

Analysis of the circuit diagram of the two compressors' phase failure protection

Analysis of the circuit diagram of the two compressors' phase failure <br><br> Air compressor phase failure <br><br> circuit In the figure, KP is the electrical contact pressure gauge Ai is the CD4073 AND gate circuit, Az is the ~D4025 NOR gate circuit, and A3 is the CD4071 OR gate circuit. The 7806 three-terminal fixed integrated voltage regulator is used as the control circuit for the DC working power supply. When the AC power fails, the relay KA is released and the motor stops.

Classification of air-conditioning compressors

The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The working circuit is divided into an evaporation area (low pressure area) and a condensation area (high pressure area). The indoor unit and outdoor unit belong to the high-pressure or low-pressure area (depending on the working state), and the compressor is generally installed in the outdoor unit.
