Technical Field

Background

With the continuous improvement of the living standard of people, the air conditioner is more and more widely applied. Because the summer is indoor comparatively moist, and the air conditioner is in the refrigeration mode, lead to user's comfort level lower. Therefore, many air conditioners are provided with a dehumidifying device to solve the problem of indoor air humidity in summer.

The traditional household air conditioner mostly adopts a mode of jointly adjusting temperature and humidity, namely, the temperature and the humidity are adjusted by the same adjusting device in a coordinated mode. When a set of system is used for realizing refrigeration and dehumidification at the same time, in order to use a condensation method to remove indoor residual humidity, the temperature of a cold source needs to be lower than indoor dew point temperature, the temperature difference between heat transfer temperature difference and medium conveying temperature difference is considered, the 16 ℃ dew point temperature needs to be about 7 ℃, namely, an air outlet of an air conditioner needs to supply air by adopting the dew point temperature, the dew point temperature is 16 ℃, a human body comfort zone in summer is 26 ℃, and the relative humidity is 60%, so that the air outlet temperature needs to be obviously lower than the required refrigeration temperature, and a series of problems are caused.

Firstly, in an air conditioning system, the sensible heat load part accounts for more than half of the total load, the heat discharged by a high-temperature cold source and dehumidification can share a low-temperature cold source of 5-7 ℃ together, so that the waste of energy utilization grade is caused, and the energy waste is caused; meanwhile, although the humidity (moisture content) of the air subjected to condensation and dehumidification meets the requirement, the temperature is too low, and the temperature difference between the air temperature and the body surface temperature is large, so that the comfort level is reduced; in addition, the air is cooled and dehumidified in a condensing mode, the ratio of sensible heat and latent heat absorbed by the air can only change within a certain range, while the heat-humidity ratio actually required by a building changes within a larger range, and when the temperature and humidity are adjusted by using the same set of existing system, the control on the humidity can only be sacrificed, the indoor relative humidity is over-high or over-low due to the fact that the requirement of the indoor temperature is met to be compromised, the relative humidity is uncomfortable as a result of over-high relative humidity, the set value of the indoor temperature is further reduced, the thermal comfort is improved by reducing the indoor temperature, and the energy consumption is unnecessarily increased; finally, people are increasingly installing fresh air systems, and when fresh air is introduced, the relative humidity is too low, which leads to the increase of energy consumption for processing the fresh air due to the increase of enthalpy difference with the outdoor.

Therefore, how to realize independent adjustment of temperature and humidity to improve the comfort of the air conditioner is a problem to be solved by those skilled in the art. Meanwhile, when the temperature and the humidity are independently regulated, because the number of required parts is increased, how to realize the optimization of structural arrangement in the air conditioner is also the problem which is faced currently.
