The invention discloses an unloading expansion valve heat pump unit, a control method and device thereof and a storage medium. The unloading expansion valve heat pump unit comprises a compressor, an unloading expansion valve, a temperature measurement module and a control module, and the control module controls the opening degree of the unloading expansion valve according to the output temperatureinterval. The unloading expansion valve is applied to a heat pump unit, and a control logic is configured for the unloading expansion valve, so that the unloading expansion valve can be controlled, fine adjustment of the output temperature can be realized, the rapid fine adjustment of the output temperature can be realized, and when the unloading expansion valve heat pump unit is applied to occasions such as material drying, various drying processes can be easily realized. Compared with some output temperature fine adjustment technologies realized by using a digital scroll compressor or a variable frequency compressor, fine adjustment of the output temperature is realized by using the unloading expansion valve, and the cost is reduced. The unloading expansion valve heat pump unit is widely applied to the technical field of heat pumps.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to an unloading expansion valve heat pump unit and its control method, device and storage medium. Background technique [0002] Most of the existing heat pump units use fixed-frequency compressors. Although they can output stable heat, when they are used in material drying and other occasions, it is often necessary to control the temperature of the material to change in multiple stages to achieve various drying processes. Existing heat pump units are difficult to achieve precise and rapid temperature control. [0003] Terminology Explanation [0004] Unloading expansion valve: It is an application form of electronic expansion valve. The electronic expansion valve uses the electrical signal generated by the adjusted parameters to control the voltage or current applied to the expansion valve, so as to achieve the purpose of adjusting the liquid supply. The electronic expansion v...
