Description
Technical field
The present invention relates to technical field of air conditioner, particularly relate to a kind of air-conditioner temperature dehumidification control method.
Background technology
We are mixed by dry air and water vapour by the air of contact, and under certain temperature conditions, the water vapour that 1kg dry air can hold is limited, and when reaching ultimate attainment, we are called saturation state.The dry-bulb temperature of air under this state, wet-bulb temperature, dew-point temperature are identical.Dew-point temperature, when namely cooling air to this temperature, the water vapour in air can condense precipitation, and air reaches capacity state.
The principle of air conditioner dehumidification is, when the high-temperature air with steam flows through the evaporator fin of low temperature, because the effect of cooling of evaporimeter makes the temperature of air reach with below dew-point temperature, go out so the part water vapour in air can condense into elutriation, thus reach the object of dehumidifying.
General air-conditioner dehumidifier work allows the very fast fin by evaporimeter of air unlike refrigeration, because like that steam has little time condensation and just runs out and get back to indoor, so during dehumidifier work, indoor fan operating rate is general comparatively slow, allows the moisture in air obtain sufficient condensation.
That is, because air-conditioner dehumidifier equally can reduce air themperature, dehumidifier can cause the reduction of indoor temperature equally.Under dehumidifier state, the compressor being responsible for refrigeration is not continuous firing, but interrupted carries out dehumidifier, makes indoor temperature reduce directly refrigeration so so severe.
Existing room air conditioner, when dehumidifying running, adopts above-mentioned dehumidification mode, more single.Above-mentioned dehumidification mode controls not make personalized selection for multiple climatic environment, user namely can not be provided better more to select, can't meet the high request of user for amenity.
Summary of the invention
The object of the present invention is to provide a kind of air-conditioner temperature dehumidification control method, have multiple dehumidification mode, user can make personalized selection for multiple climatic environment, meets the high request of user for amenity.
The present invention is achieved through the following technical solutions:
Air-conditioner temperature dehumidification control method, wherein, includes multiple dehumidification mode, that is: cool-down dehumidification pattern, constant temperature dehumidification pattern and intensification dehumidification mode; Dehumidifying runs and starts, after the control system of air-conditioner receives the selection instruction of dehumidification mode, the temperature and humidity condition of current indoor, external environment is judged, reach after service condition according to selected mode operation, when the control system of air-conditioner judges that the temperature of indoor environment is or/and when damp condition meets termination condition, air-conditioner terminates to run.
Beneficial effect of the present invention is as follows:
Air-conditioner temperature dehumidification control method of the present invention, owing to including multiple dehumidification mode, that is: cool-down dehumidification pattern, constant temperature dehumidification pattern and intensification dehumidification mode; Dehumidifying runs and starts, after the control system of air-conditioner receives the selection instruction of dehumidification mode, the temperature and humidity condition of current indoor, external environment is judged, reach after service condition according to selected mode operation, when the control system of air-conditioner judges that the temperature of indoor environment is or/and when damp condition meets termination condition, air-conditioner terminates to run.Air-conditioner arranges three kinds of dehumidification modes according to temperature requirements, i.e. cool-down dehumidification, constant temperature dehumidification, intensification dehumidifying, unit runs according to target temperature value, solve and carry out different dehumidification modes selectively under different temperatures environment, damp condition: under hot and humid condition, apply cool-down dehumidification pattern, dehumidify while air-conditioner refrigeration; Apply constant temperature dehumidification pattern under middle temperature super-humid conditions, dehumidify while temperature constant; Apply intensification dehumidification mode under low temperature and high relative humidity condition, after first heating intensification, constant temperature dehumidifies again.
The present invention is better relative to existing control method, and when hot and humid environment needs dehumidifying, dehumidify while refrigeration cool-down, temperature and humidity declines simultaneously fast.Refrigerating capacity under this pattern is relatively large, and the speed of cooling is fast; In the middle of warm high humidity environment when needing dehumidifying, slightly cooling or simultaneously dehumidify under keeping temperature constant state again after heating up, can keep on the basis of temperature constant, humidity declines; Running when first opening heating mode under low temperature and high relative humidity environment, after raising indoor temperature, then carrying out constant temperature dehumidification.Temperature steady temperature again after first significantly raising, humidity declines simultaneously, and the heating capacity under this pattern is comparatively large, can raised temperature fast, meets the high request of user for amenity.
