Problems solved by technology
[0002] In the air conditioning equipment system of the prior art, there is no oil equalization circuit outside the unit, and the balance can only be controlled by controlling the amount of refrigerant (oil amount) entering each compression module. Therefore, the oil balance control is relatively passive and cannot be effectively guaranteed reliability

The invention discloses a module oil balancing device and a module oil balancing control method for a compressor system. The module oil balancing device comprises compression modules, wherein each compression module comprises a compressor, an oil separator, a four-way valve, an outdoor heat exchanger, a gas-liquid separator and an oil balancing loop; one end of each compressor is connected with the first end of the corresponding four-way valve via the corresponding oil separator; the second end of each four-way valve is connected with the corresponding outdoor heat exchanger; the third end of each four-way valve is connected with the other end of the corresponding compressor via the corresponding gas-liquid separator; and an oil discharge opening in each oil separator is connected with one end of the corresponding oil balancing loop. As the oil balancing loops are arranged at the oil discharge openings in the oil separators, sufficient oil can be provided for each compression module in the compressor system, refrigeration oil among all the compression modules can be balanced, and the running reliability of the compressor system can be guaranteed.
Description
technical field [0001] The invention relates to the field of compressor systems, in particular to a modular oil equalization device and a control method for a compressor system. Background technique [0002] In the air conditioning equipment system of the prior art, there is no oil equalization circuit outside the unit, and the balance can only be controlled by controlling the amount of refrigerant (oil amount) entering each compression module. Therefore, the oil balance control is relatively passive and cannot be effectively guaranteed reliability. Contents of the invention [0003] Embodiments of the present invention provide a module oil equalization device and control method of a compressor system with simple structure and low cost, so as to ensure that each compression module in the system has sufficient oil volume, so that the refrigeration oil between each compression module balance, so as to ensure the reliability of unit operation. [0004] In order to achieve t...
