Heating control method and air conditioner

Abstract

The invention provides a heating control method and an air conditioner. The heating control method includes the steps that the outdoor ambient temperature, the condensing pressure information and theindoor ambient temperature are collected according to a preset time period; when it is judged that a low-temperature powerful heating mode is started according to the first outdoor ambient temperature, a preset temperature interval to which the first outdoor ambient temperature belongs is matched; if the first outdoor ambient temperature belongs to a first temperature interval, the operating parameters of a compressor or an outer fan of the air conditioner are controlled according to the saturation temperature corresponding to the condensing pressure information and the indoor ambient temperature, wherein the preset temperature interval includes the first temperature interval, that is to say, when it is determined that the low-temperature powerful heating mode is started and the outdoor ambient temperature still belongs to the first temperature interval, the heating capacity attenuation degree is determined according to the saturation temperature corresponding to the condensing pressure information and the indoor ambient temperature, and the operating parameters of the compressor or the outer fan of the air conditioner are controlled accordingly so as to improve the heating effectof the air conditioner and improve the use experience of a user.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heating control method and an air conditioner. Background technique [0002] Air conditioning products are mainly used to adjust the temperature condition in the controlled environment through cooling or heating. Conventional air-conditioning products include two parts, an indoor unit and an outdoor unit, and the core component of the air-conditioning product, the compressor, is arranged in the outdoor unit. In the heating mode of the air conditioner, the compressor installed on the outdoor unit heats the refrigerant, and transfers the heated refrigerant to the indoor unit for heat release, so as to increase the temperature of the controlled environment. [0003] However, in a low-temperature environment, the heating capacity of a compressor located outdoors will be attenuated by the environment, and the attenuation degree is different under different temperature cond...

AI Technical Summary

Problems solved by technology

[0003] However, in a low temperature environment, the heating capacity of an outdoor compressor will be attenuated by the environment, and the degree of attenuation is different under different temperature conditions

In particular, the heat loss of multi-connected air conditioners is particularly large, which directly affects the heating effect and user experience
