Description

Technical Field

[0001] The present invention relates to the technical field of constant temperature and humidity air conditioners, and particularly relates to an energy-saving constant temperature and humidity air conditioner and a control method for high-temperature and high-humidity environments. Background Art

[0002] With the rapid development of the household appliance industry, air conditioners have entered thousands of households, improving the living conditions of the people. In some places in the south of China, the air humidity is high and the environmental temperature is high, which affects people's home experience. Therefore, people usually use air conditioners at home to reduce the environmental humidity and improve the living experience.

[0003] At present, the existing air conditioners mainly have two modes for dehumidification: the refrigeration mode and the dehumidification mode. When the air conditioner is in the refrigeration mode, the temperature of the humid air will drop significantly after passing through the evaporator of the air conditioner. The air humidity is in a supersaturated state, and the excess water vapor precipitates in the form of condensed water, thus reducing the air humidity. However, this will cause the condensed water to adhere to the surface of objects, affecting the living experience. The dehumidification mode is also called the constant temperature dehumidification mode. The principle is that the air is cooled by the evaporator and then heated to the original temperature, and then sent into the room, so that the indoor environment maintains a relatively constant temperature while the humidity drops. Existing household air conditioners usually cannot adjust the temperature in the dehumidification mode. The temperature is usually set by the manufacturer and is basically close to the environmental temperature. However, when the environmental temperature is high, people's perceived temperature will be high, affecting the living experience. Therefore, users need to switch repeatedly between the dehumidification mode and the refrigeration mode, which affects the user experience and is not conducive to air conditioner energy conservation, so there is a need for improvement.

At the same time, a plurality of temperature sensors 7 and humidity sensors 8 for detecting the ambient temperature and humidity are fixedly arranged on the air conditioner base 1. The temperature sensors 7 and the humidity sensors 8 can collect the ambient temperature and humidity in real time and submit them to the control system. The control system controls the flow rate of the refrigerant flowing into the secondary dehumidification pipeline 4 and the secondary cooling pipeline 5 through the set values of the user, so as to realize the reasonable distribution of the refrigerant and reduce the energy consumption.

[0028] Reference Figure 2, specifically, the main dehumidifying and cooling pipeline 3 includes a main compressor 31 and a condenser 32 connected to the main compressor 31.

In this embodiment, the main compressor 31 uses a fixed-frequency compressor, and the first auxiliary compressor 41 and the second auxiliary compressor 51 both use small variable-frequency compressors, which not only reduce the energy consumption but also reduce the usage cost of using large variable-frequency compressors, and at the same time improve the dehumidification and refrigeration effects of the air conditioner.

After dehumidification is completed, the dry air is discharged through the third outlet fan 43, which further improves the dehumidification effect of the air conditioner with lower energy consumption. A dust-proof net 24 is fixedly installed at the air inlet of the air induction seat 21 to prevent foreign objects, dust in the air or hands from reaching into the air induction seat 21 and causing harm.
