Abstract
The utility model provides a throttle device for an air conditioner with a long pipe. The throttle device comprises an outdoor heat exchanger, an indoor heat exchanger, and a liquid line of the long pipe, wherein, the liquid line of the long pipe is connected between the outdoor heat exchanger and the indoor heat exchanger; the throttle device is characterized in that the throttle device further comprises a heating throttle valve core part, a stop valve and a cooling throttle valve core part; the heating throttle valve core part, the stop valve and the cooling throttle valve core part are sequentially connected in series on the pipeline of the liquid line of the long pipe; the heating throttle valve core part is connected with the outdoor heat exchanger; and the cooling throttle valve core part is connected with the indoor heat exchanger. As the throttle device adopts the structure that the heating throttle valve core part, the stop valve and the cooling throttle valve core part are sequentially connected in series on the pipeline of the liquid line of the long pipe, the heating throttle valve core part is connected with the outdoor heat exchanger, and the cooling throttle valve core part is connected with the indoor heat exchanger, throttling is conducted through the indoor heat exchanger during cooling, and through the outdoor heat exchanger during heating, heat loss of the system during cooling/heating is reduced, the capacity of the system is caused to be high, frost formation during heating is reduced, and safe and reliable operation is ensured.
Description
Technical field
The utility model relates to a kind of throttling arrangement of long pipe arrangement air-conditioning, belongs to the improvement technology of the throttling arrangement of long pipe arrangement air-conditioning.
Background technology
The throttle style of existing long pipe arrangement air-conditioning has two kinds, and the one, outer machine throttling, the 2nd, interior machine throttling, when outer machine throttling, the air conditioner refrigerating energy loss is big, and system's refrigerant is mobile weak, thereby the system capability deficiency, and pressure is higher; When interior machine throttling, it is big that air-conditioning heats energy loss, and system's refrigerant flows weak thereby the low easy frosting of system condensing device lateral pressure.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of and can avoid at refrigeration/system energy loss when hot that system capability is abundant, heats the throttling arrangement of frosting long pipe arrangement air-conditioning few and safe and reliable to operation.
The technical solution of the utility model is: a kind of throttling arrangement of long pipe arrangement air-conditioning, comprise outdoor heat exchanger, indoor heat exchanger, be connected the long pipe arrangement liquid pipe between outdoor heat exchanger and the indoor heat exchanger, it is characterized in that also including and heat throttling valve core parts, stop valve and refrigeration throttling valve core parts, heating throttling valve core parts, stop valve and refrigeration throttling valve core parts is serially connected on the pipeline of long pipe arrangement liquid pipe successively, heat the throttling valve core parts and be connected with outdoor heat exchanger, refrigeration throttling valve core parts are connected with indoor heat exchanger.
The utility model is because employing heats throttling valve core parts, stop valve and the throttling valve core parts that freeze are serially connected on the pipeline of long pipe arrangement liquid pipe successively, heating the throttling valve core parts is connected with outdoor heat exchanger, the structure that refrigeration throttling valve core parts are connected with indoor heat exchanger, during refrigeration by interior machine throttling, by outer machine throttling, therefore, it has reduced in refrigeration/loss of system capacity when hot when heating, make system capability abundant, heat few frosting and safe and reliable to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Structural representation of the present utility model as shown in Figure 1, comprise outdoor heat exchanger 1, heat throttling valve core parts 2, stop valve 3, refrigeration throttling valve core parts 5 and indoor heat exchanger 6, be connected the long pipe arrangement liquid pipe 4 between outdoor heat exchanger 1 and the indoor heat exchanger 6, heating throttling valve core parts 2, stop valve 3 and refrigeration throttling valve core parts 5 is serially connected on the pipeline of long pipe arrangement liquid pipe 4 successively, heat throttling valve core parts 2 and be connected with outdoor heat exchanger 1, refrigeration throttling valve core parts 5 are connected with indoor heat exchanger 6.
During the utility model refrigeration, the refrigerant of HTHP stream successively through external heat exchanger 1, heat throttling valve core parts 2, stop valve 3, refrigeration throttling valve core parts 5 and indoor heat exchanger 6 when realizing refrigeration in the machine throttling, when heating the refrigerant of HTHP flow through successively indoor heat exchanger 6, refrigeration throttling valve core parts 5, stop valve 3, heat throttling valve core parts 2 and external heat exchanger 1, outer machine throttling when realizing heating.
