Problems solved by technology

[0003] The first method is to reduce the enthalpy when the indoor circulating air passes through the refrigerant. This method is widely used in small air conditioners, but it lacks fresh air and the indoor air quality is not good.
[0004] The second method is to send the outdoor fresh air into the room through the refrigerant to reduce the enthalpy, and the indoor air is discharged. This method consumes too much energy and does not use the indoor air to dissipate heat.
[0005] The third method is to exchange heat between the outdoor fresh air and the indoor exhaust air through a sensible heat or total heat exchanger, and then send it into the room after the enthalpy is reduced by the refrigerant. This method can recover part of the cold or heat through heat exchange, but there is still some loss
[0007] At present, there is no air conditioning method that can effectively use the indoor exhaust air to take away heat, so that the enthalpy of the indoor exhaust air is higher than the enthalpy of the outdoor air.

Embodiment Construction

[0032] The present invention will be described in detail below according to the accompanying drawings.

[0033] Such as figure 1 As shown, the indirect evaporative cooler includes two channels, dry and wet. When a stream of gas flows into the indirect evaporative cooler, a part of the gas is humidified in the wet channel, and the liquid evaporates to absorb the heat of the gas in the dry channel, and the gas in the dry channel is equalized. For wet cooling, the wet bulb temperature of the gas in the wet channel can theoretically be equal to the initial dry bulb temperature of the gas in the dry channel. There are two situations for the dry bulb temperature of the gas in the dry channel. In one case, the dry bulb temperature can theoretically reach the wet bulb temperature of the gas sent into the wet channel, such as figure 1 As shown in (a); in another case, the dry bulb temperature can theoretically reach the dew point temperature of the gas sent into the wet channel, such ...

Abstract

The invention discloses a method for regulating the indoor air environment by regulating enthalpy value of indoor exhaust air, i.e. regulating the state of indoor exhaust air until its enthalpy value approaches to the enthalpy limit value. On the refrigerating condition, the state of the enthalpy limit value of the indoor exhaust air is that the wet ball temperature is equal to the highest dry ball temperature occurring in the regulating course; on the heating condition, the state is that the wet ball temperature is equal to the lowest dew point temperature. The invention has the technical effects of high efficiency and saving energy, and ability to provide new air and increase indoor net refrigeration quantity and simultaneously reduce energy consumption.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a method for adjusting an indoor air environment. Background technique [0002] At present, there are several methods for indoor air environment regulation: [0003] The first method is to reduce the enthalpy when the indoor circulating air passes through the refrigerant. This method is widely used in small air conditioners, but it lacks fresh air and the indoor air quality is not good. [0004] The second method is to send the outdoor fresh air into the room through the refrigerant to reduce the enthalpy, and the indoor air is exhausted. This method consumes too much energy and does not use the indoor air to dissipate heat. [0005] The third method is to exchange heat between the outdoor fresh air and the indoor exhaust air through a sensible heat or total heat exchanger, and then send it into the room after the enthalpy is reduced by the refrigerant. T...
