Abstract
The invention relates to a mildew proof control method for air condition room evaporator that includes the following steps: sending shut up instruction, judging whether starting mildew proof mode, taking mildew proof process, ending mildew proof process and shutting up compressor. In the mildew proof process, it has processes of shutting up indoor machine fan and reversing four-way valve, and opening indoor machine air deflector to maximum. In the ending mildew proof process, it has the processes of shutting up indoor machine air deflector and stopping compressor, and reversing four-way valve. After shutting up, the indoor fan stops working, but system still running. By reversing exchanging of secondary refrigerant, the temperature of evaporator rising, and the water would be vaporized, opening deflector, the vapor would be dispersed into air. Thus, evaporator would avoid mildew, and air indoor would be clean.
Description
Technical field
The present invention relates to a kind of indoor apparatus of air conditioner.Particularly relate to a kind of evaporimeter that can suppress in the indoor apparatus of air conditioner and produce the mildew-proof control method for evaporator of air-conditioner indoor unit that goes mouldy.
Background technology
Air-conditioner is to carry out cooling-heating room or air cleaning is that purpose is provided with cold-room machine, house heater, pure and fresh machine etc. indoor generally speaking, possessed in order to build comfortable indoor environment to the user carry out heat exchange after can sucking indoor air or purify after be discharged to air-supply arrangement and the cooling-heating room device and the air cleaning unit of indoor mandatory mobile room air once more.
Air-conditioner is according to application target and the position is set can be divided into multiple class, and its indoor set ordinary circumstance includes on-wall type, cabinet type, ceiling type.Whatsoever the indoor set of style all is provided with evaporimeter, indoor machine fan in it, is formed with air inlet and air outlet on its housing, and also is provided with the wind-guiding baffle plate at the air outlet place.
Fig. 1 is the internal structure schematic diagram of the ceiling-mounted air conditioner indoor set of prior art.
As shown in Figure 1, the internal structure of the indoor set part of the ceiling-mounted air conditioner of prior art includes, 4 rotations of motor drives fan produce air-flow, airflow passes is positioned at the evaporimeter 2 around the fan 4, after evaporimeter 2 makes air-flow cooling or heating, air-flow flows out along the air outlet 7 of the upper end of housing 1, and air-out direction is by 6 controls of air outlet guide plate.
But, for the cold-warm type air-conditioning indoor set, after carrying out refrigerating operaton, have condensed water on the indoor machine evaporation, if shutdown at once, condensed water can not be removed, time has been grown and can go mouldy on evaporimeter, when moving air-conditioning once more, the wind that blows out can have the taste that goes mouldy, and indoor air has been caused pollution.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of evaporimeter that can suppress in the indoor apparatus of air conditioner to produce the mildew-proof control method for evaporator of air-conditioner indoor unit that goes mouldy.
The technical solution adopted in the present invention is: a kind of mildew-proof control method for evaporator of air-conditioner indoor unit is by finishing as the next stage: the stage of sending shutdown command; Judge whether to open the stage of mildew-resistant pattern; Carry out the stage that mildew-resistant is handled; Finish mildew-resistant and handle the stage of close compressor.
In the stage of carrying out the mildew-resistant processing, include and close the step that indoor machine fan commutates cross valve and indoor set wind-guiding baffle plate reached maximum.
Handle finishing mildew-resistant, close in the stage of air-conditioner, include and close indoor set wind-guiding baffle plate and stop the drive compression machine, and with the step of cross valve commutation.
Mildew-proof control method for evaporator of air-conditioner indoor unit of the present invention, after shutdown, indoor fan quits work, system is not out of service, by the back exchange of refrigerant, the temperature of evaporimeter rises, and quickens the evaporation of moisture, open baffle plate simultaneously, vaporized steam is dispersed in the air, removes the condensed water on the evaporimeter, guaranteed the dry and comfortable of evaporimeter, avoided producing on the evaporimeter and gone mouldy, kept the pure and fresh of room air.
Description of drawings
Fig. 1 is the internal structure schematic diagram of air conditioner room unit;
Fig. 2 is the flow chart of mildew-proof control method for evaporator of air-conditioner indoor unit of the present invention.
The specific embodiment
Below, be described with reference to the accompanying drawings mildew-proof control method for evaporator of air-conditioner indoor unit of the present invention.
Mildew-proof control method for evaporator of air-conditioner indoor unit of the present invention is by finishing as the next stage: the stage S1 that sends shutdown command; Judge whether to open the stage S2 of mildew-resistant pattern; Carry out stage S3, S4 that mildew-resistant is handled; Finish mildew-resistant and handle stage S5, the S6 of close compressor.
Judging whether to open among the stage S2 of mildew-resistant pattern, when not needing to carry out the mildew-resistant processing, directly shutdown when needs carry out the mildew-resistant processing, then enters and carries out stage S3, the S4 that mildew-resistant is handled.
In carrying out stage S3, the S4 that mildew-resistant handles, include and close indoor machine fan commutate S3 and indoor set wind-guiding baffle plate is reached the step of maximum S4 of cross valve.Wherein, the cross valve commutation is meant the direction that changes the refrigerant circulation, the refrigerant of heat is flow in the indoor set housing, the indoor machine evaporation temperature rises, quicken the condensation evaporation of water above it, owing to indoor machine fan is not worked, so can not carry out the cold and hot exchange of room air, just open the wind-guiding baffle plate at utmost, steam is dispersed in the air.Stage S3, the S4 that mildew-resistant is handled got final product in lasting 2 minutes.
Handle finishing mildew-resistant, among stage S5, the S6 of close compressor, include close indoor set wind-guiding baffle plate S5 and stop the drive compression machine, with the commutate step of S6 of cross valve.Wherein, stop the drive compression machine, and, be that compressor is no longer worked the cross valve S6 that commutates, and in front S3 changed in the step to cross valve commutate once more and turn back to former direction.
The present invention is after shutdown, and system is not out of service, and the fan of indoor set is closed and no longer works, so can not carry out the cold and hot exchange of room air again.With the cross valve commutation of off-premises station, compressor still continues operation, makes the refrigerant of heat flow to indoor set, and the temperature of indoor machine evaporation rises, and quickens the evaporation of moisture, owing to simultaneously the wind-guiding baffle plate is reached maximum, the moisture that evaporates can be dispersed in the air.After continuing 2 minutes under this state, the condensed water on the indoor machine evaporation has been evaporated totally, closes wind-guiding baffle plate machine again, and four energy thresholds are commutated gets back to previous status and get final product.
