Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0019] see figure 1 As shown, according to an embodiment of the present invention, a control method of a compressor system is provided. The compressor system includes a condenser, an electronic expansion valve, an evaporator, and a compressor connected in sequence. The control method includes the following steps:
[0020] Step S10: Obtain the operating parameters of the compressor, and determine the air intake of the compressor according to the operating parameters;
[0021] Step S20: Obtain the opening degree of the electronic expansion valve;
[0022] Step S30: Adjust the opening of the electronic expansion valve according to the opening of the electronic expansion valve and the suction volume.
[0023] Through the real-time monitoring of the operating parameters of the compressor,...

The invention provides a control method for a compressor system and the compressor system. The control method for the compressor system includes the steps that operation parameters of the compressor are obtained and according to the operation parameters, the air inflow of the compressor is confirmed; the opening degree of an electronic expansion valve is obtained; and according to the opening degree of the electronic expansion valve and the air inflow, the opening degree of the electronic expansion valve is adjusted. By the adoption of the control method for the compressor system, the problem that liquid is brought to sucked air of a compressor due to the fact that the liquid supply amount of an electronic expansion valve and the air inflow of the compressor are not matched in the prior art is solved effectively.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a control method of a compressor system and the compressor system. Background technique [0002] In the prior art, the electronic expansion valve, as one of the important components of the compressor steam cycle system, plays the role of throttling and adjusting the liquid supply, and plays a vital role in the performance of the compressor system. The electronic expansion valve Although the valve has good flexibility, the control of the existing electronic expansion valve takes the exhaust superheat and the suction superheat as the main reference, and uses the PID algorithm to realize the control of the electronic expansion valve, but this electronic expansion In terms of control, the valve has the disadvantage of a narrow range. The variable in the adjustable range is small and the control accuracy is not high enough, which leads to the mismatch between the liquid supply v...
