Embodiment Construction

[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] The present invention proposes an air conditioning system that detects the open state of the electric auxiliary heating element when the air conditioning system is running in the heating mode, and simultaneously controls the frequency increase of the compressor when the electric auxiliary heating element is about to be turned off, so as to avoid electric auxiliary heating When the heating element is turned off, the temperature of the air outlet suddenly drops suddenly, which makes people feel uncomfortable, and thus effectively solves the problem of heating comfort.

[0038] The above-mentioned air-conditioning system can include various types. According to the installation method, it can include hanging machine, cabinet machine, ceiling machine, window machine, mobile air conditioner, embedded air conditioner; ...

Abstract

The invention discloses an air conditioning system, comprising a compressor, an evaporator, a condenser, electric auxiliary heating elements and throttling elements, wherein the air conditioning system further comprises a controller for detecting compressor running frequency when the air conditioning system runs at a heating mode and the electric auxiliary heating elements are in an opening state; when the compressor running frequency is more than or equal to a first preset frequency threshold, the electric auxiliary heating elements are closed and the compressor is controlled for raising frequency; according to the air conditioner setting temperature and the present indoor environment temperature, the air conditioning system is controlled for heating. The invention further discloses a control method of the air conditioning system. By the air conditioning system, feelings uncomfortable to persons are prevented because air outlet temperature is instantaneously decreased when the electric auxiliary heating elements are closed, and the problem of heating comfort is effectively solved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning system and a heating control method thereof. Background technique [0002] Air conditioners are favored by users due to their ability to regulate humidity. In the prior art, when the air conditioner is running in the heating mode, when the electric auxiliary heat of the auxiliary heating meets the shutdown condition, the prior art is to directly shut down, and then the frequency of the compressor is adjusted according to the set temperature. [0003] However, when the electric auxiliary heating is turned off, the power of the air conditioner will drop a lot, which will cause the temperature of the air outlet of the air conditioner to drop sharply, which will affect the comfort of the air conditioner, and there will be a clear feeling of cool wind. Contents of the invention [0004] The main purpose of the present invention is to provide an air-conditioning s...
