Problems solved by technology

[0002] At present, people pay more and more attention to the impact of air-conditioning refrigerants on the environment. In order to protect the atmospheric ozone layer, it is common practice to use new refrigerants R410A or R407C to replace traditional air-conditioning refrigerants R22, but these two refrigerants are subject to the "Kyoto Protocol" The HFCS-type greenhouse effect gas that is controlled and emitted is not a completely ideal refrigerant, while natural refrigerants have the least impact on the environment and are ideal for long-term replacement.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Generally speaking, heating and cooling air conditioners have the anti-cold wind function, that is, when the user starts heating, the machine will not immediately enter the set wind operation, but will gradually change from fan stop, breeze, Low wind can reach the set wind at the end. Of course, it can also be from fan stop, breeze, low wind, middle wind to set wind or from fan stop, breeze, to set wind, etc. The principle is as follows: figure 1 shown. For compressors in air conditioners, refrigerant deposition is the worst operating condition, and the oil film thickness usually reaches a minimum value at this time.

[0022] Such as figure 2 As shown, it is a data statistical chart of refrigerant deposition in an air conditioner using refrigerant R290 as refrigerant. The data results show that after the refrigerant is deposited and before the...

Abstract

The invention relates to a heating control method of an air conditioner. The method comprises the following steps of powering on the air conditioner, and entering a heating mode; adopting an outdoor machine to detect an outdoor ambient temperature T3, and adopting an indoor machine to detect an indoor ambient temperature T1; enabling an air damper and an air guide angle of the indoor machine to be operated according to the setting of a user or to be operated according to a preset value, and enabling the air damper and the air guide angle of the indoor machine to be operated in priority according to a cold-air preventing mode if the cold-air preventing mode is needed; enabling an indoor fan to enter a high-air running mode if T3A is more than T3 and T1 is more than T1A, and adopting a cold-air preventing angle mode for an air guide angle of the indoor fan; withdrawing from the high-air running mode, and enabling the air conditioner to run the air damper according to a normal cold-air preventing mode; and enabling the air conditioner to enter a set air mode according to the normal cold-air preventing mode if T3 is less than T3A and T1 is more than T1A. By adjusting the operation mode of the air conditioner, the thickness of an oil membrane of a running part of a compressor can be efficiently increased, the thickness and viscosity of the oil membrane of the air conditioner under a worst working condition can be guaranteed, the reliability of the compressor is improved, and the operation reliability of the air conditioner can be guaranteed.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a heating control method for the air conditioner. Background technique [0002] At present, people pay more and more attention to the impact of air-conditioning refrigerants on the environment. In order to protect the atmospheric ozone layer, it is common practice to use new refrigerants R410A or R407C to replace traditional air-conditioning refrigerants R22, but these two refrigerants are subject to the "Kyoto Protocol" The HFCS-type greenhouse gases that are controlled and emitted are not completely ideal refrigerants, while natural refrigerants have the least impact on the environment and are ideal for long-term replacement. Among them, R290 (propane) is a natural refrigerant with an ozone depletion coefficient of 0, a small greenhouse coefficient, and excellent thermal performance. It is an ideal substance for long-term replacement of refrigerant R22. [0003] Under the condition of sat...
