Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] The invention provides a method for increasing the low-temperature heating capacity of an inverter air conditioner. The essence of the method is to install an auxiliary electric heating device in the inverter air conditioner, and control the auxiliary electric heating device through a main control unit of the air conditioner. When the condition for turning on the auxiliary electric heating is met, the main control unit sends a control signal to control the operation of the auxiliary electric heating device to compensate the heating effect of the air conditioner to increase the heating capacity of the air conditioner; and when the condition for turning off the auxiliary electric heating is met , the main control unit sends a control signal to control the auxiliary electric heating device to stop working, so as to achieve the purpose of energy saving.

Abstract

The invention discloses a method for improving low-temperature heating capacity of a convertible frequency air-conditioner and the convertible frequency air-conditioner. The convertible frequency air-conditioner comprises a main control unit and an auxiliary electrical heating device. Under a start-up condition of auxiliary electrical heating, the main control unit controls the electrical heating unit to work, and, under a stop condition of auxiliary electrical heating, the main control unit controls the electrical heating unit to stop working, thereby improving the heating capacity of the convertible frequency air-conditioner during low-temperature heat generation and saving energy during low-temperature heat generation.

Description

technical field [0001] The invention relates to a heating method for an inverter air conditioner, in particular to a method for increasing the low-temperature heating capacity of an inverter air conditioner, and belongs to the technical field of air conditioners. Background technique [0002] At present, heating air conditioners on the market include ordinary fixed-speed air conditioners, fixed-speed air conditioners with auxiliary electric heating, and inverter air conditioners. The compressor speed of ordinary fixed-speed air conditioners is constant. Generally speaking, the best ambient temperature of this type of air conditioner is about 6°C when heating. For every 1°C decrease in the inlet air temperature, the heating effect will be reduced by about 5%. . Therefore, as the temperature drops, ordinary fixed-speed air conditioners often fail to heat, and even fail to start heating at lower temperatures. [0003] In order to solve the above-mentioned defects of low-tempe...
