Abstract
The utility model discloses a heat pump air conditioner, which comprises a compressor, a cross reversing valve, a condenser, an evaporimeter, and a throttling component which are connected through refrigerant pipelines, wherein the condenser and the evaporimeter are selectively communicated with the compressor through the cross reversing valve; and the air conditioner further comprises a bothway stop valve, and the bothway stop valve is connected in parallel with the throttling component. In the utility model, the bothway stop valve can quickly balance the pressure in refrigerant pipelines, and can realize the quick restarting of the heat pump air conditioner.
Description
Technical field
The utility model relates to the domestic air conditioner field, particularly a kind of heat pump air conditioner.
Background technology
Heat pump air conditioner is in normal course of operation, if after receiving halt instruction, indoor control panel carries out direct power down process to compressor of outdoor unit and four-way change-over valve.Because pressure in the existence of the throttle part between heat pump air conditioner condenser and the evaporimeter, heat pump air conditioner condenser and the pressure in the evaporimeter are difficult to reach balance at short notice.If this moment start can cause phenomenons such as the excessive or compressor start failure of starting current, thereby can not guarantee the operation that air-conditioner is safe and reliable.Usually, air-conditioning producer can require the air-conditioning shutdown just can restart after three minutes, but has following drawback:
1, air-conditioner can not restart fast.When the user starts shooting, by a remote controller, then must wait three parts of clocks could open air-conditioning again afterwards as many; The user is badly in need of regulating air-conditioner temperature as this moment, then must wait three minutes again and afterwards could open air-conditioning once more; Because of not restarting fast, certainly will reduce the comfortableness of air-conditioner, cause user's complaint.
2, resolution system pressure balance problem fundamentally.When capillary was longer, the system pressure equilibration time increased, in addition may be after three minutes pressure lack of equilibrium also; Start this moment, might cause the big or startup failure phenomenon of system's starting current, to causing great influence the service life of air-conditioner.
The utility model content
The utility model purpose is, a kind of heat pump air conditioner is provided, and can restart fast.
At above-mentioned technical problem, the heat pump air conditioner that the utility model provides, its technical scheme is: comprise the compressor, four-way change-over valve, condenser, evaporimeter and the orifice union that connect by the refrigerant pipeline, described condenser and described evaporimeter are communicated with described compressor by described four-way change-over valve selectivity; Also comprise two-way shut-off valve, be in parallel with described orifice union.
Described orifice union comprises choke valve.
Described orifice union comprises capillary.
Described orifice union comprises electric expansion valve.
Be respectively arranged with stop valve on the refrigerant pipeline at described evaporimeter two ends.
Compared with prior art, the two-way shut-off valve of the utility model increase and orifice union parallel connection can make air-conditioner thus after shutdown, and the pressure of heat pump air conditioner is balance fast, makes air-conditioning be in normal wait open state constantly.After air-conditioning receives start-up command, can start fast freeze, heating operation, the comfortableness and the service life thereof of improving air-conditioning thus greatly.
Description of drawings
Fig. 1 is the schematic diagram of the utility model heat pump air conditioner, and among the figure, refrigerant flowed to when dotted line line arrow was represented to freeze, and refrigerant flowed to when solid arrow was represented to heat.
Relevant Reference numeral is:
1, compressor; 2, four-way change-over valve; 3, condenser; 4, two-way shut-off valve; 5, orifice union; 6, first stop valve; 7, evaporimeter; 8, second stop valve.
The specific embodiment
Basic design of the present utility model is, increases and the two-way shut-off valve of orifice union parallel connection, makes the pressure balance fast of heat pump air conditioner, thus the quick startup of realization heat pump air conditioner.
Describe below in conjunction with accompanying drawing and embodiment.
Referring to Fig. 1, this figure is the schematic diagram of the utility model heat pump air conditioner.This heat pump air conditioner is made up of critical pieces such as compressor 1, four-way change-over valve 2, condenser 3, two-way shut-off valve 4, orifice union 5, first stop valve 6, evaporimeter 7 and second stop valves 8, wherein:
Four-way change-over valve 2 is used to switch the positive and negative flow direction of refrigerant;
Orifice union 5 is arranged on the refrigerant pipeline; Orifice union 5 is capillary or electric expansion valve, in order to regulate the flow of refrigerant in the refrigerant pipeline; Regulate orifice union 5 and also can be choke valve, regulate the flow of refrigerant by the aperture of adjusting choke valve;
First stop valve, 6, the second stop valves 8 are arranged on the refrigerant pipeline at evaporimeter 7 two ends, in order to increase pipeline section pressure, and then the whole refrigerant pipeline of balance.
Two-way shut-off valve 4, in parallel with orifice union 5, with the pressure balance of refrigerant pipeline in the quick realization heat pump air conditioner.
In the air conditioner refrigerating running, refrigerant glide path is as follows: compressor 1 → four-way change-over valve 2 → condenser 3 → orifice union 5 → the first stop valves 6 → evaporimeter 7 → the second stop valves 8 → four-way change-over valve 2 → compressor 1, finish kind of refrigeration cycle.At this moment, two-way shut-off valve 4 not conductings, air-conditioning normally moves, and it is high that the pressure in the pressure ratio evaporimeter 7 in the condenser 3 is wanted; When air-conditioning is shut down, two-way shut-off valve 4 conductings, the high pressure refrigerant in the condenser 3 flows in evaporimeter 7 rapidly, thereby makes the rapid balance of heat pump air conditioner pressure.
In the air-conditioning heating process, heat pump air conditioner refrigerant glide path is as follows: compressor 1 → four-way change-over valve 2 → the second stop valves 8 → evaporimeter 7 → orifice union 5 → the first stop valves 6 → condenser 3 → four-way change-over valve 2 → compressor 1 is finished and is heated circulation.At this moment, not conducting of two-way shut-off valve, air-conditioning normally moves, and it is high that the pressure in the pressure ratio condenser 3 in the evaporimeter 7 is wanted; When air-conditioning is shut down, two-way shut-off valve 4 conductings, the high pressure refrigerant in the evaporimeter 7 flows in condenser 3 rapidly, thereby makes the rapid balance of heat pump air conditioner pressure.
Usually, adopt the heat pump heat pump air conditioner of two-way shut-off valve, after the shutdown, heat pump air conditioner pressure can reach balance in 10 seconds.Compare with the system pressure equilibration time that existing common heat pump air conditioner is about 3 minutes; the heat pump air conditioner pressure balance time shortens dramatically; and then the normal open state of waiting for was prepared greatly to shift to an earlier date after air-conditioning was shut down, and effectively raised the comfortableness and the service life thereof of air-conditioning.
The method for restarting of this heat pump air conditioner is: after shutdown, make air-conditioner be in holding state; When receiving start-up command, air-conditioner is started shooting again.Preferably, the minimum stand-by time of air-conditioner is 10S, realizes the quickest restarting.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
