Problems solved by technology

[0002] The existing air-conditioning systems all have dehumidification function, and the dehumidification method is the same as the cooling method; the difference is that the indoor unit opens the low windshield, and the compressor and indoor fan are turned on for a few minutes and stopped for a few minutes; this method can dehumidify the room, but When cooling the room in this way, while reducing the latent heat (lower humidity) in the room, it will also reduce the sensible heat (lower temperature) in the room, which makes people feel uncomfortable.

Embodiment 1

[0025] A kind of air-conditioning dehumidification method of keeping constant temperature of the present embodiment, comprises the following steps:

[0026] S1. Divide the heat exchanger of the indoor unit into two systems;

[0027] S2. The two systems are connected through a conversion device;

[0028] S3. When heating or cooling normally, the conversion device is closed, and both systems are used for the condenser or evaporator at the same time;

[0029] S4. When dehumidification is in progress, turn on the conversion device, and the two systems are converted into condenser and evaporator respectively. At this time, the heat added by the condenser is equal to the heat of the sensible part of the dehumidification reduction, so as to maintain the dehumidification process and keep the temperature unchanged. .

[0030] It should be noted that when the air conditioner is cooling, the heat exchanger of the indoor unit is an evaporator; when the air conditioner is heating, the he...

Embodiment 2

[0036] see Figure 1-3 : This embodiment also discloses a constant temperature air-conditioning dehumidification system, including a compressor 8, an indoor unit heat exchanger 1, an outdoor unit heat exchanger 7, a conversion device, and a first throttling element 6; the compressor 8 , the indoor unit heat exchanger 1, the first throttling element 6, and the outdoor unit heat exchanger 7 are sequentially connected to form an air-conditioning and refrigeration system, wherein the indoor unit heat exchanger 1 is divided into two systems, and the two systems are directly converted through The devices are connected; when the conversion device is closed, the two systems of the indoor unit heat exchanger are used as an evaporator as a whole, and when the conversion device is opened, the two systems of the indoor unit heat exchanger are respectively used as the evaporator of the indoor unit heat exchanger 1. 2. Indoor unit heat exchanger 2. 3 (condenser at this time).

Abstract

The invention discloses an air conditioner dehumidification method and system capable of keeping constant temperature. The method comprises the steps of dividing a heat exchanger of an indoor unit into two systems; connecting the two systems through a switching device; turning off the switching device when normal heating or refrigerating is conducted, wherein at this moment, the two systems are both used as a condenser or an evaporator simultaneously; and turning on the switching device when dehumidification is carried out, wherein at this moment the two systems are switched to the condenser and the evaporator for use respectively, the heat added to the condenser is equal to sensible heat reduced during dehumidification, and thus the temperature is kept constant in the dehumidification process. During normal use, the two systems are taken as one system to participate in the refrigeration and heating functions of an air conditioner; and under the dehumidification function, one part of the heat exchanger is adopted as the evaporator to achieve the effects of refrigeration and dehumidification, the rest part of the heat exchanger is taken as one part of the condenser to participate inthe effect of heat release with an outdoor condenser so as to conduct heating and balance the temperature lowered due to reduction of sensible heat during refrigeration of the evaporator, and in thisway, the function of keeping the indoor temperature is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner dehumidification method and system for maintaining a constant temperature. Background technique [0002] The existing air-conditioning systems all have dehumidification function, and the dehumidification method is the same as the cooling method; the difference is that the indoor unit opens the low windshield, and the compressor and indoor fan are turned on for a few minutes and stopped for a few minutes; this method can dehumidify the room, but When cooling the room in this way, while reducing the latent heat (lower humidity) in the room, it also reduces the sensible heat (lower temperature) in the room, which makes people feel uncomfortable. [0003] Based on this, an air conditioner dehumidification method and system that maintains a constant temperature is now studied. By dividing the (heat exchanger) evaporator of the indoor unit into two systems a...
