Description
Technical Field
The invention relates to the field of control methods of air water generators, in particular to a condensation water taking control method of an evaporator of an all-working-condition air water generator.
Background
With the increasing living standard and health consciousness of people, an air water generator (also called air water taking) becomes a high-end consumer product at present and is emerging in the market continuously. At present, the mainstream air water generator adopts an evaporation compression type refrigeration principle, namely, a compressor, an evaporator, a condenser, a throttling element and the like are connected through pipelines to form a refrigerant circulation loop, the evaporator is provided with an evaporation fan, the condenser is provided with a condensation fan, air flows in from the air inlet side of the evaporator under the action of the evaporation fan, flows out from the air outlet side of the evaporator after passing through the evaporator, and low-temperature and low-pressure liquid refrigerant in the compressor is subjected to gasification phase change in a tube of the evaporator, so that the air on the outer surface of the evaporator is cooled and forms condensed water, and a water source of the air water generator is formed by collecting the condensed water. In the prior art, since an evaporator, a condenser, a compressor, etc. are solidified according to the design of a product system, the adaptability thereof is not excellent enough to face the change of complicated and severe environmental conditions.
For example, the ambient dry bulb temperature range of a common civil air water making machine is 18-43 ℃, and the ambient wet bulb temperature range is 35-95%. Meanwhile, the air water generator is different from an air conditioner in that the air conditioner has an indoor working condition and an outdoor working condition for test evaluation, but the air water generator is tested under the same environmental temperature and humidity condition, for example, some manufacturers determine that the dry bulb temperature is 27 ℃ and the relative humidity is 60% as a rated test working condition. Under the relatively stable working condition, the product design can be better carried out so as to obtain the ideal evaporation temperature and meet the condensation water outlet of the evaporator. However, the surface of the evaporator sometimes does not condense or some places do not condense any more with the change of the environmental temperature and humidity, so that the water outlet effect is poor. When the temperature range of the environment dry bulb is expanded to 5-55 ℃, the temperature range of the environment wet bulb is expanded to 10-95%, and particularly when the humidity is low, the phenomenon that the surface of an evaporator is not condensed is more and more serious, the water yield within the required range cannot be reached, and even high-temperature protection and the like are caused.
The surface temperature of the evaporator fins is a physical phenomenon that condensate water is generated as long as the surface temperature is lower than the dew point temperature of the surrounding air. Of course, if the evaporation temperature is designed to be very low (such as-10 ℃), condensation can be met under all working conditions. However, for vapor compression refrigeration, this design will cause low system energy efficiency, and cannot meet the future requirement for energy saving. In the face of different environmental humiture, under the condition that the evaporator can not change the volume or the heat exchange area, a dynamic evaporator fin temperature control method is needed to enable the evaporator to effectively condense moisture.

In fig. 3, the water intake area is divided into a non-water intake area and a water intake area, and the lowest dew point temperature of the design of the water generator is taken as a boundary. Wherein the lowest dew point temperature T 1 dew min At the lowest dry bulb temperature T in the working temperature range 1min Corresponding dew point temperature limit and maximum dry bulb temperature T 1max The lower of the corresponding dew point temperature limits. If the minimum working temperature is 5 ℃ and the relative humidity limit value is 38.2% (dew point temperature-7 ℃), the maximum working temperature is 55 ℃ and the relative humidity limit value is 10% (dew point temperature 13.81 ℃), then T 1 dew min -7 ℃ as borderline value. At this time, the relative humidity can theoretically be expanded to 2.1% at an ambient temperature of 55 ℃. As can be seen from the figure, the water taking area is wider than the environmental area (18 ℃ -43 ℃) of the common air water making machine, and the water taking area has no blind area.
