Abstract
The utility model discloses a split air conditioner with a defrosting function. The split air conditioner comprises a compressor, a four-way valve, a condenser, an indoor side heat exchanger, an outdoor side heat exchanger and a capillary pipe, wherein a first valve port of the four-way valve is connected with an exhaust pipe of the compressor; a second valve port of the four-way valve is connected with the indoor side heat exchanger; a third valve port of the four-way valve is connected with a muffler of the compressor; a fourth valve port of the four-way valve is connected with the outdoor side heat exchanger; a defrosting switching pipeline and a flow direction control switch are arranged between the compressor and the first valve port of the four-way valve; the defrosting switching pipeline consists of a defrosting pipe and a run-through pipe which are connected with each other in parallel; and the flow direction control switch is used for connecting the defrosting pipe or the run-through pipe to the compressor and the first valve port of the four-way valve in an alternate mode. In the utility model, the defrosting pipe is additionally arranged on the base plate of the outdoor unit, even if the air conditioner heats under a low-temperature environment, a frost layer/ice layer on an air conditioner base plate can be quickly melted.
Description
Technical field
The utility model relates to the air-conditioning technique field, more particularly, relates to a kind of split-type air conditioner with the defrost function.
Background technology
In the prior art, pump type heat family expenses room air conditioner is to adopt air-cooled cold face temperature etc.When air was flowed through heat exchanger, if when the coil temperature of outdoor heat exchanger is lower than the dew-point temperature of air, airborne moisture will be separated out and be attached to coil surface and be formed the frost layer.The temperature difference between coil surface and the intake air is big more, and frosting speed is fast more, and frosting is also serious more.Along with the formation of frost layer, the heating capacity of air-conditioning descends.When air-conditioning reached the defrosting condition, the starting of air conditioner defrosting mode was with the white stratification Cheng Shui that condenses on the condenser.Water flows on the chassis along condenser, discharges from the osculum on chassis.When the air-conditioner defrosting pattern finished, the water on the chassis did not often drain only.When air-conditioning moved heating mode once more, when the frost of lowermost copper pipe of condenser or fin surface contacted with the water on the chassis, the water on the chassis will condense into ice sheet.The air-conditioning long-play will be tied the thick ice of one deck on the chassis.When air-conditioning reached the defrosting condition once more, the frost on the air-conditioning condenser changed into water and flows on the chassis, and it is clean that the ice sheet on the chassis is difficult to quiltization, and the ice cube of Rong Huaing can not blocked the chassis delivery port, makes that the water on the off-premises station chassis can not be got rid of.When air-conditioning during sub-zero environmental work, the water of failing to exclude will soon condense into ice cube and be attached to the condenser bottom.Water on the condenser can not be smoothly discharged towards the chassis, very fast up frosting rapidly under the condenser.The quick increase of the defrosting time of air-conditioning and defrosting number of times, heating capacity sharply descends, thereby can not guarantee the temperature that the room is indoor.
The utility model content
The utility model purpose is to provide a kind of split-type air conditioner with the defrost function, make air-conditioning when the low temperature environment startup heats, can melt the ice sheet on the chassis fast, thereby make that flowing on the chassis water can get rid of fast swimmingly, alleviated the frosting degree of condenser, reduce the defrosting time and defrosting number of times of air-conditioning, improve the heating capacity of air-conditioning.
The technical scheme that the utility model adopted is: a kind of split-type air conditioner with the defrost function, comprise compressor, cross valve, condenser, indoor heat exchanger, outdoor heat exchanger, capillary, first valve port of described cross valve connects the blast pipe of compressor, second valve port of cross valve connects indoor heat exchanger, the 3rd valve port of cross valve connects the muffler of compressor, the 4th valve port of cross valve connects outdoor heat exchanger, between first valve port of described compressor and cross valve, be provided with defrost conversion pipeline and flow to gauge tap, the defrost pipe of described defrost crossover connection route parallel connection and straight pipe constitute, and the described gauge tap that flows to makes defrost pipe or straight pipe connect first valve port of described compressor and cross valve in the mode of selecting.
In the split-type air conditioner of above-mentioned band defrost function, described defrost pipe is located at the below of outdoor heat exchanger.
In the split-type air conditioner of above-mentioned band defrost function, described defrost pipe is located on the chassis of off-premises station.
In the split-type air conditioner of above-mentioned band defrost function, be provided with auxilliary capillary between described indoor heat exchanger and the capillary, described auxilliary both sides capillaceous are provided with bypass line, and bypass line is provided with check valve.
In the split-type air conditioner of above-mentioned band defrost function, the described gauge tap that flows to is a three-way magnetic valve.
In the split-type air conditioner of above-mentioned band defrost function, the described gauge tap that flows to comprises the magnetic valve that is located at respectively on defrost pipe, the straight pipe.
The beneficial effects of the utility model are:
1) because the utility model has increased a defrost pipe on the off-premises station chassis.Even when air-conditioning heats under low temperature environment, also can melt the frost layer/ice sheet on the air-conditioning chassis apace, thus the feasible water that flows on the chassis can get rid of smoothly fast, alleviated the frosting degree of condenser, reduce defrosting time and defrosting number of times, improve the heating capacity of air-conditioning.
2) when opening the refrigeration mode of air-conditioning summer, the defrost pipe on the chassis can increase the degree of supercooling of air-conditioning system, can improve the heat exchange effect.
