Control method for air source heat pump unit, electronic equipment, and computer-readable storage medium

Abstract

The present invention relates to a control method for an air source heat pump unit, electronic equipment, and a computer-readable storage medium. The control method, the electronic equipment, and thecomputer-readable storage medium are used to accurately obtain the real-time heating / cooling quantity in the unit for feedback, so that after-sales service personnel is convenient to carry out troubleshooting and achieve quick repair; the method includes the following steps performed sequentially: a real-time heating / cooling quantity Q monitoring step, which is used for monitoring the actual watertemperature T1 of the unit, and calculating the real-time heating / cooling quantity Q of the unit when the actual water temperature T1 is lower than the target water temperature T2; a warning step, which is for triggering the unit to give different types of warnings according to comparison results between the real-time heating / cooling quantity Q and the standard heating / cooling quantity Q1.

Description

technical field [0001] The invention relates to the field of air conditioning, and in particular to a control method for an air source heat pump unit, electronic equipment, and a computer-readable storage medium. Background technique [0002] During the operation of the air source heat pump, in order to ensure the heating of the room, the heating capacity of the unit must be able to meet the heat load demand of the house. However, the structure of the unit of the existing air source heat pump is as follows: figure 1 As shown, only compressor 1, four-way valve 2, fan 3, outdoor refrigerant-air heat exchanger 4, outdoor temperature sensor 5, electronic expansion valve 6, liquid receiver 7, water-refrigerant heat exchanger 8. Composed of 9 gas-liquid separators, this structure does not have the ability to accurately know the real-time heating / cooling capacity. Once the indoor temperature is too low / high, the unit will only blindly increase heating / cooling according to the tempe...

[0002] During the operation of the air source heat pump, in order to ensure the heating of the room, the heating capacity of the unit must be able to meet the heat load demand of the house. However, the structure of the unit of the existing air source heat pump is as follows: figure 1 As shown, only compressor 1, four-way valve 2, fan 3, outdoor refrigerant-air heat exchanger 4, outdoor temperature sensor 5, electronic expansion valve 6, liquid receiver 7, water-refrigerant heat exchanger 8. Composed of 9 gas-liquid separators, this structure does not have the ability to accurately know the real-time heating / cooling capacity. Once the indoor temperature is too low / high, the unit will only blindly increase heating / cooling according to the temperature feedback. On the one hand It will increase power consumption. On the other hand, it will cause after-sales service personnel to be unable to judge whether the indoor temperature is too low / high due to insufficient heating / cooling capacity of the unit or excessive room heat and cooling load, which will cause many changes in maintenance work.
