Abstract
The present invention provides a dehumidification method for indoor air, which relates to a method for dehumidifying the indoor air by using a refrigeration process. An evaporator fan is periodically turned on and turned off in the operation process of the dehumidification, so the reduction of the room temperature is delayed, and the dehumidification is sufficiently carried out. The relative humidity of the indoor air is reduced to a desired range at the time as maintaining the room temperature.
Description
One, technical field
The present invention relates to a kind of method of utilizing refrigeration process that room air is dehumidified.
Two, background technology
The device that utilizes traditional refrigeration process to carry out air dewetting is made up of compressor, condenser, expansion valve and evaporimeter; Compressor compresses and converts to the gas refrigerant of high temperature and high pressure to gas refrigerant, condenser converts the gas refrigerant of above-mentioned high temperature, high pressure to the liquid refrigerant of middle temperature, high pressure, expansion valve converts the liquid refrigerant of middle temperature, high pressure to the liquid refrigerant of low temperature, low pressure again, and evaporimeter then converts the liquid refrigerant of low temperature, low pressure to the gas refrigerant of low temperature, low pressure.This traditional refrigeration process dehydrating unit is identical with the composition of general aircondition, therefore, utilizes general aircondition and selects dehumidification function, can become the dehydrating unit that utilizes refrigeration process.When cold-producing medium evaporates in above-mentioned evaporimeter, evaporimeter ambient air temperature will descend, and airborne water vapour is got rid of because of the cooling frosting and with the form of condensed water, thereby realizes dehumidifying.Like this, when the dehumidifying operation, because the effect of evaporimeter, in fact indoor temperature will descend.In order to prevent that this temperature from descending, in the dehumidifying running, must periodically turn on and off power of compressor; But this method that turns on and off compressor power but is difficult to keep effectively the relative humidity of air.
Fig. 1 is the effect on moisture extraction figure of traditional air dehumidification method.
As shown in Figure 1, during the dehumidifying operation, indoor air themperature also will decrease.But owing to be conceived to dehumidifying, so the reduction of indoor temperature should have certain limit.Minimum indoor temperature among the figure is set at-1 ℃, when indoor temperature drops to-1 ℃, indoor temperature need be raise again.For this reason, traditional dehydrating unit is that compressor power periodically is switched on or switched off.During compressor shutdown, indoor temperature rises; When indoor temperature rises to uniform temperature, restart compressor again, to keep certain temperature.This shutdown of compressor and restarting will constantly be carried out in whole dehumidifying running.Yet, from this dehumidification mode as can be seen, although relative humidity does not drop to required scope as yet; but because the decline of indoor temperature; compressor will be shut down, and therefore, relative humidity also will be gone up again and just implement dehumidifying when being higher than required relative humidity scope.Obviously, traditional dehumanization method can not remain on relative humidity in the required scope effectively.
Three, summary of the invention
Purpose of the present invention promptly is a kind of indoor air dehumidifying method is provided, and makes it when keeping certain indoor temperature, and the relative humidity in the room air is reduced in the required scope.
To achieve these goals, the present invention is utilizing refrigeration process to dehumidify when operation, periodically starts and closes evaporator fan.
Adopt above method can delay the reduction of indoor temperature, when keeping indoor temperature, the relative humidity of room air can be reduced to the scope that needs.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment indoor air dehumidifying method of the present invention.
Four, description of drawings
Fig. 1 is the effect on moisture extraction figure of traditional dehumanization method.
Fig. 2 is effect on moisture extraction figure of the present invention.
Five, the specific embodiment
As shown in Figure 2, the difference of the present invention and traditional dehumanization method is, the evaporator fan (being indoor fan) that plays exsiccation is periodically started and closes.When indoor fan is closed, the reduction of indoor temperature will be suppressed; And owing to do not provide hot-air to evaporimeter, thereby the temperature of evaporimeter just becomes lower, and serious decline can't appear in moisture removal.This point can be clear that from following formula:
Moisture removal=air quantity * when indoor fan is closed, air quantity will reduce (air themperature-evaporator surface temperature), but the evaporator surface temperature that contacts with hot-air reduces equally, and therefore, big difference can't appear in moisture removal.
Like this, utilize the periodicity startup of indoor fan and close the reduction that can delay indoor temperature, compare with traditional dehumanization method, compressor turned on and off cycle stretch-out, thereby can be more fully the relative humidity of room air be reduced in the required scope.Also promptly as shown in Figure 2, prolong the working time that indoor temperature drops to compressor before-1 ℃, also prolonged the dehumidifying time of evaporimeter thereupon, thereby had more time to reduce indoor relative humidity more fully.
In sum as can be known, the present invention can delay the reduction of indoor temperature, thereby can fully dehumidify by periodically starting and closing evaporator fan.
