Abstract
The utility model relates to a heat pump type air conditioner defroster. A compressor, an indoor heat exchanger, a decompressor and an outdoor heat exchanger are connected through a pipeline to form a heating circuit, in which a first bypass circuit and a second bypass circuit are arranged as well; a first electromagnetic valve is arranged between the decompressor and the outdoor heat exchanger, and is connected in parallel with the first bypass circuit, on which a heater is arranged; and a decompressing capillary and a second electromagnetic valve are arranged in the second bypass circuit, one end of which is connected between the exhaust outlet of the compressor and the indoor heat exchanger and the other end of which is connected between the first electromagnetic valve and the outdoor heat exchanger. The utility model has the advantages that: (1) during defrosting, the indoor unit still operates to heat, so that the indoor temperature is not notably fluctuated, and thereby a user can feel more comfortable; (2), during defrosting, two routes of high-temperature refrigerant converges and then enters the heat exchanger of the outdoor unit to thaw frost, the flow velocity and flow rate of the refrigerant are increased, and the defrosting time is shortened.
Description
Technical field
The utility model relates to a kind of air-conditioner with heat-production functions, particularly a kind of heat pump air conditioner defroster.
Background technology
At present, the general cross valve that adopts switches, makes the cold-producing medium reverse flow in the freezing loop to defrost thereby heat pump air conditioner defrosts.In when defrosting, the flow direction of cold-producing medium is identical when freezing, machine heat exchanger outside the exhaust inlet chamber of the HTHP that comes out from compressor, thus the frost that is attached on the off-premises station heat exchanger is melted.In this defrost process, because indoor heat exchanger has become evaporimeter, can siphon away indoor heat, indoor temperature is descended, it is uncomfortable that the user can feel.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, operation convenience, when heating, realize defrost, with stablizing of user's room temperature during the assurance defrost, improve the heat pump air conditioner defroster of user's comfortableness, to overcome weak point of the prior art.
A kind of heat pump air conditioner defroster by this purpose design, comprise by compressor, indoor heat exchanger, pressure reducer and outdoor heat exchanger heating the loop by what pipeline was connected, its architectural feature is to heat also to be provided with first bypass circulation and second bypass circulation in the loop; Be provided with first magnetic valve between pressure reducer and the outdoor heat exchanger, first magnetic valve is in parallel with first bypass circulation, and first bypass circulation is provided with heater; Be provided with the step-down capillary and second magnetic valve in second bypass circulation, the one end is connected between exhaust outlet of compressor and the indoor heat exchanger, and the other end is connected between first magnetic valve and the outdoor heat exchanger.
Described first magnetic valve is a normal-open electromagnetic valve, and second magnetic valve is the closed type magnetic valve.
The suction inlet of described compressor is connected with indoor heat exchanger with outdoor heat exchanger respectively by cross valve with exhaust outlet.
The described first bypass circulation middle spiral winding, spiral winding or snakelike winding on heater, flow through time of heater, be able to sufficient heating thereby prolonged the refrigerant medium.
The utlity model has following advantage:
1, indoor set is still pressed heating operation during defrost, makes the indoor temperature not have obvious fluctuation, thereby has improved user's comfortableness.
2, during defrost, converge the outer machine heat exchanger of back inlet chamber by the two-way high temperature refrigerant and carry out defrosting, accelerated refrigerant flow rate and flow, shortened the defrost time.
3, the improvement of this system pipeline is little, can reach the purpose that heats defrost simultaneously in simple, reliable mode.
4, this structure can be fit to have the air-conditioner of single heat-production functions, also is applicable to the cold-warm type air-conditioning device.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, this heat pump air conditioner defroster, comprise by compressor 1, indoor heat exchanger 3, pressure reducer 4 and outdoor heat exchanger 5 heating the loop by what pipeline was connected, the suction inlet of compressor 1 is connected with indoor heat exchanger 3 with outdoor heat exchanger 5 by cross valve 2 with exhaust outlet.Heat and also be provided with first bypass circulation 12 and second bypass circulation 13 in the loop; It is in parallel with first bypass circulation 12 to be provided with first magnetic valve, 6, the first magnetic valves between pressure reducer 4 and the outdoor heat exchanger 5, and first bypass circulation is provided with heater 7; Be provided with the step-down capillary 9 and second magnetic valve 8 in second bypass circulation 13, the one end is connected between cross valve 2 and the indoor heat exchanger 3, and the other end is connected between first magnetic valve 6 and the outdoor heat exchanger 5.First magnetic valve 6 is a normal-open electromagnetic valve, and second magnetic valve 8 is the closed type magnetic valve.The 12 middle spiral windings of first bypass circulation are on heater 7.
Its operation principle is: when normal heating operation, first magnetic valve 6 is often opened, and second magnetic valve 8 is normally closed, when outdoor heat exchanger 5 frostings to a certain degree, automatically controlled detect reach the defrost condition after, complete machine enters the defrost state.When system's defrost, cross valve 2 does not commutate, and first magnetic valve 6 cuts out, and second magnetic valve 8 is opened, and heater 7 is opened state when cross valve 2 still is in heating operation.The high-temperature gas refrigerant of discharging from compressor is divided into two-way (seeing refrigerant flow arrow the figure) after by cross valve 2, machine heat exchanger 3 heats in one road inlet chamber, become liquid refrigerants after heating and after pressure reducer 4 carries out throttling, flow into first bypass circulation 12, in first bypass circulation, be heated into the high-temperature gas refrigerant by heater 7; Another road high-temperature gas refrigerant that flows out from cross valve 2 flows into second bypass circulation 13, carries out converging with the high-temperature gas refrigerant that flows out from heater 7 after the step-down through step-down capillary 9, flows into outdoor heat exchanger 5 together and carries out defrost.During defrost, indoor fan 10 is with low wind operation, and outdoor fan 11 shuts down.After defrost finished, first magnetic valve 6 was opened, and second magnetic valve 8 cuts out, and heater 7 cuts out, and set condition turned round before indoor fan 10 and outdoor fan 11 returned to defrost.
Above-mentioned indoor set heat exchanger 3 and indoor fan 10 constitute indoor set 14, and compressor 1, cross valve 2, pressure reducer 4, outdoor heat exchanger 5, first magnetic valve 6, heater 7, second magnetic valve 8, step-down capillary 9, outdoor fan 11, first bypass circulation 12 and second bypass circulation 13 constitute off-premises station 15.
