Abstract

The invention discloses an unloading expansion valve heat pump unit and its control method, device and storage medium. The unloading expansion valve heat pump unit includes a compressor, an unloading expansion valve, a temperature measurement module and a control module. Opening of the unloading expansion valve. The invention applies the unloading expansion valve to the heat pump unit, and configures the control logic for the unloading expansion valve, which can realize the control of the unloading expansion valve, thereby realizing the fine adjustment of the output temperature and the rapid fine adjustment of the output temperature. When the expansion valve heat pump unit is used in occasions such as material drying, it is easy to realize various drying processes. Compared with some output temperature fine-tuning technologies that use digital scroll compressors or inverter compressors, using unloaded expansion valves to achieve fine-tuning of output temperature helps to reduce costs. The invention is widely used in 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...
