Abstract
The invention discloses a snow cover prevention control method for a fan of an outdoor unit of an air conditioner. The method comprises the following steps: judging whether the function of snow cover prevention is opened or not when the snow falls; if the function of snow cover prevention is not opened, stopping the function of snow cover prevention; if the function of snow cover prevention is opened, judging whether the outdoor temperature is lower than the set snow removing temperature or not; if the outdoor temperature is higher than the set snow removing temperature, stopping the function of snow cover prevention; if the outdoor temperature is lower than the set temperature removing temperature, judging whether the outdoor unit is in the stop state or not; if the outdoor unit is in the running state, stopping the function of snow cover prevention; and if the outdoor unit is in the stop state, carrying out the function of snow cover prevention. The control logic of applying the function of snow cover prevention is added on the outdoor unit of the air conditioner, therefore, an outdoor switch used for snow cover prevention is added, and the snow is removed by the fan which automatically runs for two minutes in every 30 minutes when the outdoor unit stops and the function of snow cover prevention is opened during snowing.
Description
Technical field
The present invention relates to air-conditioner outdoor unit, especially the snow cover prevention control method of fan of outdoor unit of air conditioner.
Background technology
Usually, air-conditioning be divided into off-premises station and indoor set be arranged on one in the casing package AC plant and compressor and condenser be arranged in the outdoor casing as off-premises station, evaporimeter is arranged on indoor detachable air conditioner as indoor set.
Recently,, therefore in large-scale air-conditioner, on off-premises station, be equipped with several compressors, satisfied various refrigeration requirements effectively because market is more and more higher to the requirement of the refrigerating capacity of detachable air conditioner.
As shown in Figure 1, the off-premises station 100 of the air-conditioner of prior art comprises: the inner spatial accommodation that forms, and the side is provided with the right angle hexahedron casing 110 of hatch frame; Be arranged on the shared gas-liquid separator 120 and the several compressors 130 of casing 110 inside; The outdoor heat converter that carries out the cold-producing medium heat exchange 140 along casing 110 interior periphery settings.
Casing 110 comprises: adopt tetragonal structure, be arranged on the bottom, support the chassis 111 of shared gas-liquid separator 120, compressor 130 and heat exchanger 140 etc.; Adopt tetragonal structure, maintain a certain distance, be arranged on the top board 115 of the top on chassis 111; Be arranged at several munnions 114 between chassis 111 and the top board 115 on the above-below direction.
On top board 115, run through the plate face and be provided with hatch frame, and in each open area, be provided with respectively, promote several Air Blast fans 150 of outdoor heat converter 140 heat exchange by send air to the outside.
Periphery along each side and back on chassis 111 is provided with a plurality of outdoor heat converters 140, and the shared gas-liquid separator 120 of a pair of compressor 130 being installed and gaseous refrigerant being provided to each compressor 130 in the inside of outdoor heat converter 140.
Being provided with by extrusion forming along the side of outdoor heat converter 140 is the drainage channel 112 of groove, and running through drainage channel 112 bottom surfaces has several osculums 113.When defrosting running, drainage channel 112 is discharged to the outside by osculum 113 with dissolving the defrost water of back drippage or the snow-broth and the rainwater of inflow casing 110 inside on the outdoor heat converter.
When the air-conditioner of the prior art of above-mentioned formation heats running, heat the high-temperature high-pressure refrigerant of back outflow behind outdoor expansion valve (not expression among the figure) at indoor set (not having expression among the figure) by off-premises station 100, decompression is also expanded, the inside of inlet chamber outer heat-exchanger 140, and the low temperature liquid cold-producing medium of inflow outdoor heat exchanger 140 inside is under the effect of Air Blast fan, carry out heat exchange and absorb heat with the outdoor air that flows into the low-temperature condition in the casing, become the cryogenic gaseous cold-producing medium.Then, the cryogenic gaseous cold-producing medium carries out gas-liquid separation in shared gas-liquid separator 120 after, flow into each compressor 130 inside with the state of pure gas and be compressed, high-temperature gas cold-producing medium (not expression among the figure) circulation repeatedly in indoor set thus.
Above-mentioned air-conditioner is in heating the process of running, moisture in the outdoor air will be in the surperficial frosting of outdoor heat converter 140, reduce the heat exchange efficiency of heat exchanger, therefore carry out the defrosting running of a period of time usually, need to remove the frost on heat exchanger 140 surfaces.
The defrost water that outdoor heat converter 140 surfaces produce can flow in the recessed drainage channel 112 of outdoor heat converter 140 sides setting, and is discharged to the outside of off-premises station 100 by the osculum 113 that runs through drainage channel 112 bottom surfaces.
But above-mentioned off-premises station is at the weather that snows, and snow can be deposited in above the outdoor fan by the protecting wire net on the fan, when snow drift is long-pending too much, if use air-conditioning may cause fan to start, influences air-conditioning and uses.
Summary of the invention
Technical problem to be solved by this invention is that a kind of snow cover prevention control method that prevents the fan of outdoor unit of air conditioner of outdoor fan accumulated snow is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of snow cover prevention control method of fan of outdoor unit of air conditioner may further comprise the steps:
(1) when outdoor snowing, judges whether to open anti-accumulated snow function;
(2), finish anti-accumulated snow function operation if do not open anti-accumulated snow function; If open anti-accumulated snow function, judge whether outdoor temperature is being set below the snow removing temperature;
(3) if outdoor temperature is being set more than the snow removing temperature, finish anti-accumulated snow function operation; If outdoor temperature judges that setting below the snow removing temperature whether off-premises station is in halted state;
(4) if off-premises station, finishes anti-accumulated snow function operation in running status; If off-premises station is in halted state, the anti-accumulated snow function of operation.
Described setting snow removing temperature is 3 degree.
The anti-accumulated snow function of the operation of described step (4) is meant that outdoor fan was every operation in 30 minutes 2 minutes.
Described fan of outdoor unit of air conditioner aims at the top.
Described air-conditioning is the frequency conversion business air conditioner.
The gauge tap of described anti-accumulated snow function is arranged on the outdoor control box.
The gauge tap of described anti-accumulated snow function is arranged on the house remote control.
The invention has the beneficial effects as follows: be increased in the control logic that air-conditioner outdoor unit is used anti-accumulated snow function, increase anti-accumulated snow switch, when snowing, open anti-accumulated snow function, when off-premises station is when stopping,, remove accumulated snow every the operation two minutes automatically of 30 minutes fans.
