Problems solved by technology

This method takes into account the need for energy saving, but it also has major disadvantages: 2 / 3 or more evaporators are usually required in front of the electronic two-way valve to balance the temperature drop caused by dehumidification, while the evaporator part for effective dehumidification is only 1 / 3 3 or even less, so the dehumidification efficiency is lower

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0021] When the indoor unit of the air conditioner is in dehumidification operation, the cooling capacity required has two parts: the latent heat that generates condensed water, which is an effective part of dehumidification; and the sensible heat that causes the air temperature to drop, which will cause indoor The ambient temperature drops. The technical solution of the present invention can at least partially offset the influence of the sensible heat part on the reduction of the indoor ambient temperature. This is very beneficial to improve the user's comfort when the indoor temperature is low (such as 18-25°C mentioned in the background).

[0022] The dehumidification control method of the a...

Abstract

The invention provides a dehumidification control method for an air conditioner. The dehumidification control method includes the following steps that an indoor draught fan of the air conditioner runs, and wet air in the environment enters an indoor unit of the air conditioner; an evaporator of the air conditioner cools and dehumidifies the wet air entering the indoor unit so that low-temperature and low-humidity air can be formed; an auxiliary electric heater of the air conditioner runs and heats the low-temperature and low-humidity air, and heated low-humidity air is formed; the heated low-humidity air is exhausted to the environment. According to the dehumidification control method for the air conditioner, the auxiliary electric heater is started in a dehumidification mode, the auxiliary electric heater can control the temperature of the dehumidified air, thus, the evaporator can conduct effective dehumidification without balancing temperature drop generated by dehumidification, and the dehumidification efficiency of the air conditioner can be improved on the premise that the temperature of the dehumidified air is controlled.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, to a dehumidification control method for an air conditioner. Background technique [0002] In an environment with relatively low temperature (such as 18-25°C) and high humidity, such as the rainy season in the middle and lower reaches of the Yangtze River and coastal areas, it is difficult to dry clothes, damp furniture, and uncomfortable human body, which may even cause multiple diseases. Fungal infections cause disease. At this time, the user expects that the air conditioner does not blow out cold air during dehumidification, and even blows out warm air. [0003] In the prior art, there are air conditioners with constant temperature and dehumidification functions. The air conditioner in this prior art mainly realizes constant temperature dehumidification by adding an electronic two-way valve on the indoor side. This method takes into account the need for energ...
