Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a control method of a frequency conversion air conditioner. The control method aims to solve the problem of the poor energy saving effect of an existing air conditioning system with a waste heat recovery function. In order to achieve the purpose, the control method of the frequency conversion air conditioner can determine the frequency mode of a frequency conversion pump according to different branch operating conditions, so that frequency conversion operation of the frequency conversion pump meets basic operation requirements and hot water heating requirements of the air conditioner, and the energy saving effect of the air conditioner is improved on the basis of achieving waste heat recovering; or the control method can also determine whether the frequency conversion pump needs frequency reduction or not according to the current frequency mode of the frequency conversion pump and the change condition of the opening degree of an electronic expansion valve, under the condition that the frequency conversion pump needs frequency reduction, corresponding frequency reduction schemes are implemented in different frequency modes of the frequency conversion pump, and the energy saving effect of the air conditioner is optimized and promoted.

Description

technical field

[0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method of an inverter air conditioner. Background technique

[0002] Due to the hot weather in summer, people's water consumption will increase correspondingly, and the city's water and electricity supply will increase. Since the temperature requirement of water in summer is not very high, in the era of energy shortage, if the waste heat generated by air conditioning is used for heating Domestic water can meet people's daily needs, which can not only avoid the consumption of gas and other energy sources by hot water, but also make a certain contribution to improving the global warming effect.

[0003] An air conditioning system is now provided. Compared with the existing air conditioner, the air conditioning system includes a circulating water exchange circuit capable of absorbing the waste heat of the air conditioner and heating hot water, and a n...
