With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model is wherein described.Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with each figure and embodiment, many-sided description is carried out to the technical solution of the utility model.
In the utility model, " first ", " second " etc. are distinguished on describing, not other special implication.
Fig. 1 is the structure principle chart of an embodiment according to air-conditioning of the present utility model, as shown in Figure 1, a kind of air-conditioning with regenerative apparatus is provided, comprises: compressor 1, outdoor heat exchange device 7, indoor heat-exchanger rig 14, hydraulic pressure stop valve 5, tracheae stop valve 4 and regenerative apparatus 9.
The first pipeline 22 between outdoor heat exchange device 7 and indoor heat-exchanger rig 14 arranges hydraulic stop valve 5, the second pipeline 23 between indoor heat-exchanger rig 14 and compressor 1 arranges tracheae stop valve 4.The refrigerant exit of compressor 1 is connected with the first pipeline 22 and the second pipeline 23 respectively with import, forms refrigeration, heats circulation.
First working port of regenerative apparatus 9 is connected with the first pipeline 22 between outdoor heat exchange device 7 and hydraulic stop valve 5 by the 5th pipeline 28, and the second working port of regenerative apparatus 9 is connected with the second pipeline 23 between indoor heat-exchanger rig 14 and tracheae stop valve 4 by the 6th pipeline 29.When air-conditioning carries out heating mode work, regenerative apparatus 9 can carry out accumulation of energy, and can carry out providing heat energy when defrost runs at air-conditioning.
Air-conditioning in above-described embodiment, regenerative apparatus is increased at gas, liquid stop valve place, go for multiple air-conditioning, regenerative apparatus has the function such as accumulation of energy, defrost, and in outward appearance, in form consistent with an interior machine, store heat in heating operations, adopt the heat in regenerative apparatus to carry out defrost when system needs defrost, during can realizing defrost, indoor do not lower the temperature, by the Air-conditioner design of electrically heated control realization continuous heating, improve air-conditioning and heat comfortableness in the winter time, and structure is simple, the negligible amounts of by-pass valve control.
Fig. 2 is the structure of another embodiment according to air-conditioning of the present utility model, as shown in Figure 2, indoor heat-exchanger rig 14, hydraulic stop valve 5, outdoor heat exchange device 7 and cross valve 3 are in turn connected to form the first pipeline 22, and indoor heat-exchanger rig 14, tracheae stop valve 4 and cross valve 3 are in turn connected to form the second pipeline 23.Cross valve 3 is connected respectively by the refrigerant output of the 3rd pipeline 25, the 4th pipeline 26 and compressor 1 and refrigerant input.The flow direction of cold-producing medium or refrigerant can be switched by cross valve 11, make system can realize heating and the switching of the function such as refrigeration.
First electric expansion valve 10 is arranged on the 5th pipeline 28.Magnetic valve 11 is arranged on the 6th pipeline 29, and check valve 12 and magnetic valve 11 are arranged in parallel, and the entrance and exit of check valve 12 is connected with the 6th pipeline 29 respectively.Second electric expansion valve 6; Second electric expansion valve 6 is arranged on the first pipeline 22, and at outdoor heat exchange device 7 with between the 5th pipeline 28 and the tie point of the first pipeline 22.Vapour liquid separator 8 is arranged on the 4th pipeline 26.Oil eliminator 2 is arranged on the 3rd pipeline 25.Can according to the type of air-conditioning, such as, central air-conditioning, window machine etc., each pipeline arranges different parts.
By controlling the first electric expansion valve 10 be arranged on pipeline, its effect has 2 points:
1, judge accumulation of heat degree by accumulation of heat into and out of the pipe warming thermometer bulb temperature difference during accumulation of heat: when inlet/outlet pipe temperature close to time illustrate that accumulation of heat terminates, electronic expansion valve opening is beaten little, reduce cold medium flux; When inlet/outlet pipe pipe temperature difference is comparatively large, illustrate in accumulation of heat, electronic expansion valve opening can be increased and increase cold medium flux, improve accumulation of heat speed.
2, when defrost, if the inlet/outlet pipe temperature temperature difference is close, illustrate that refrigerant does not evaporate completely at storage heater, have back liquid risk, control flow by beating little electronic expansion valve opening, otherwise then beat large.
The check valve 12 that 6th pipeline 29 is arranged in parallel and magnetic valve 11, closed electromagnetic valve when complete machine running refrigerating or when not having accumulation of heat demand, when there being accumulation of heat demand, magnetic valve 11 is opened, and HTHP refrigerant enters regenerative apparatus 9 accumulation of heat through magnetic valve 11.And during defrost, the refrigerant after throttling absorbs through regenerative apparatus 9 gas becoming low-temp low-pressure after heat and completes refrigerant circulation through magnetic valve 11 and check valve 12 system of getting back to, the now effect of check valve 12 reduces low pressure crushing, improves complete machine efficiency.
