Abstract

The invention discloses a refrigerant recovery machine, which provides a simple structure, automatic identification and completion of recovery and self-cleaning operations during refrigerant recovery, automatic control of the whole process, time-saving and labor-saving, safe and reliable intelligent control recovery method of the refrigerant recovery machine, It solves the technical problems in the prior art that the refrigerant recovery process is greatly influenced by humans, the efficiency is low, and the recovery machine is easily damaged when it is misoperated, and even a safety accident is caused in serious cases. It includes parallel connection at the air inlet and exhaust port Between the compressor and the condenser, the compressor and the condenser are connected to the inlet port through the main valve, the compressor is connected to the exhaust port through the first synchronous valve and the bleed valve in turn, and the condenser is connected through the third synchronous valve On the exhaust port, the main valve is connected to the first synchronous valve through an intermediate pipeline, and the control system automatically controls the main valve, the first synchronous valve, the discharge valve and the third synchronous valve according to the pressure values ​​of the air inlet and the exhaust port. The connection state of the valve.

Description

technical field [0001] The invention relates to a refrigerant recovery machine, in particular to a safe and reliable intelligent control recovery method for a refrigerant recovery machine that can automatically identify and complete the recovery and self-cleaning series operations during the recovery of the refrigerant, with automatic control throughout the process, saving time and effort, and being safe and reliable. Background technique [0002] With the strengthening of people's awareness of environmental protection, the refrigerant recovery machine has been widely used, that is, the refrigerant in the refrigeration system to be repaired is recovered into the refrigerant tank through the recovery machine, but the existing recovery machine is in the process of refrigerant recovery through the operator's experience. Identify the recovery state and switch the operation steps through manual operation of the knob. The refrigerant recovery process has a large human influence fac...
