The control method of the control device of air-conditioner dehumidification mode
Technical field
The present invention relates to air-conditioner, specifically is a kind of control method of control device of air-conditioner dehumidification mode.
Background technology
The air-conditioning that has special dehumidification function in the prior art can be accomplished isothermal dehumidifying, and temperature indoor during operation approximately descends 2 ℃, and comfortableness is good, has overcome the shortcoming of conventional air-conditioning device refrigerating, dehumidifying.Its equipment needs an outdoor heat exchanger and two indoor heat exchangers, or each one of outdoor heat exchanger and indoor heat exchanger add powerful electric heater.
The former refrigerant system is as shown in Figure 1.During the dehumidifying operation, compressor 1 is discharged high temperature and high pressure gas, flows to outdoor heat exchanger 3 through cross valve 2; The 4th valve body 13 is closed at this moment, the 3rd valve body 12 is opened, first valve body 6 is closed, second valve body 11 is closed; Because the 4th valve body 13 is closed; High temperature and high pressure gas is folded to and flows through the 3rd valve body 12; Because first valve body 6 is closed, make high temperature and high pressure gas again, make in the high pressure geothermal liquid through second throttling arrangement 10 because second valve body 11 is closed again through indoor first heat exchanger 9 and become geothermal liquid in the high pressure; After 10 throttlings of second throttling arrangement, former high temperature and high pressure gas becomes the low-pressure low-temperature gas liquid mixture, is evaporated to low-temp low-pressure liquid and is compressed the machine suction at indoor second heat exchanger 8 at last.The room air circulatory system then is that first second heat exchanger 8 with low temperature carried out heat exchange after room air was inhaled into; Air themperature reduces and removes the water in air branch; Carried out heat exchange with indoor first heat exchanger 9 of high temperature again by the air of being lowered the temperature, air themperature rises and reaches the purpose of constant temperature dehumidification.Freeze normally or when heating, first valve body 6 of system, the 3rd valve body 12 are closed, and second valve body 11, the 4th valve body 13 are opened, the purpose that reaches refrigeration or heat through the switching-over of four-way.
This system has had more a heat exchanger, throttling arrangement, several valve bodies and a plurality of pipelines than conventional air-conditioning system, has increased cost greatly, and control method is complicated a lot, breaks down easily.
The latter's refrigerant system is as shown in Figure 2.During the dehumidifying operation, in order to reach good effect on moisture extraction, the evaporating temperature of evaporimeter 14 is lower than the evaporating temperature of common refrigeration during dehumidifying, and is lower through the indoor air temperature of evaporator 14; Because the indoor temperature that requires of comfort level can not be low excessively, thus use 15 pairs of room airs of electric heater to carry out heat temperature raising through evaporator 14, to reach the requirement of comfort level.This system and the big variation of conventional air-conditioning system nothing, cost can not increase, and control method is also simple, but because the use of electric heater 15 makes energy consumption rise greatly, is unfavorable for energy-conservation.
Publication number is the dehumidifying job control method that the patent of CN1727770 discloses a kind of air-conditioning; The described dehumanization method logic of the above-mentioned latter of dehumanization method logical AND of the air-conditioning in this patent is similar, and Fig. 3 is the block diagram of the dehumidifying job control method of the said air-conditioning of this patent.From figure, be not difficult to find out that this dehumidification control method is to judge by imposing a condition, and control stopping of compressor and stopping of electric heater, the purpose of realization constant temperature dehumidification.But it not only uses electric heater to increase energy consumption; Also possible unreasonable setting owing to logical AND parameter in the control method, and cause compressor and electric heater to be stopped frequently, reduce the service life of equipment.
Summary of the invention
To above-mentioned problem, the present invention provides a kind of control method of control device of air-conditioner dehumidification mode, with solve the control method that exists in the above-mentioned prior art complicated, break down and problem such as energy consumption is big easily.
