Problems solved by technology

[0002] At present, the throttling device of the heating and cooling air conditioner is generally composed of a capillary tube, or a capillary tube and another capillary tube connected in parallel with a check valve in series. Capillary throttling, so that the air conditioner cannot achieve the best working conditions under both working conditions; although the latter can be adjusted by the check valve to make the air conditioner use different lengths in cooling and heating conditions. However, since the two capillaries have the same diameter, the secondary throt

Embodiment approach 1

[0039] Embodiment 1 is provided with the circulation system of the heating and cooling air conditioner of specific throttling device, as attached figure 1 And attached figure 2 . Compressor 1, four-way reversing valve 2, outdoor heat exchanger 3, throttling device 4, indoor heat exchanger 5, heating and cooling switch 6, one-way valve 7, capillary 8, capillary 9, connecting pipeline and auxiliary equipment A cooling or heating cycle. When the heating and cooling switch 6 selects the cooling mode, the refrigerant flowing out of the compressor 1 flows through the four-way reversing valve 2 to the outdoor heat exchanger 3 to condense, and then flows through the capillary 8 and the one-way valve 7 to enter the indoor heat exchanger 5 , the refrigerant returns to the compressor 1 through the four-way reversing valve 2 after being evaporated and refrigerated in the indoor heat exchanger 5 . When the cooling and heating switch 6 selects the heating mode, the one-way valve 7 is no...

Embodiment approach 2

[0041] Embodiment 2 is provided with the circulation system of the heating and cooling air conditioner of specific throttling device, as attached figure 1 And attached image 3. Compressor 1, four-way reversing valve 2, outdoor heat exchanger 3, throttling device 4, indoor heat exchanger 5, heating and cooling switch 6, one-way valve 7, capillary 8, capillary 9, connecting pipeline and auxiliary equipment A cooling or heating cycle. When the heating and cooling switch 6 selects the cooling mode, the refrigerant flowing out of the compressor 1 flows to the outdoor heat exchanger 3 through the four-way reversing valve 2 to condense, and then flows through the one-way valve 7 and the capillary tube 8 to enter the indoor heat exchanger 5 , the refrigerant returns to the compressor 1 through the four-way reversing valve 2 after being evaporated and refrigerated in the indoor heat exchanger 5 . When the cooling and heating switch 6 selects the heating mode, the one-way valve 7 is...

Embodiment approach 3

[0043] Embodiment 3 is provided with the circulation system of the heating and cooling air conditioner of specific throttling device, as attached figure 1 And attached Figure 4 . Compressor 1, four-way reversing valve 2, outdoor heat exchanger 3, throttling device 4, indoor heat exchanger 5, heating and cooling switch 6, one-way valve 7, expansion valve 10, expansion valve 11, connecting pipeline and auxiliary The devices form a cooling or heating cycle. When the heating and cooling switch 6 selects the cooling mode, the refrigerant flowing out of the compressor 1 flows to the outdoor heat exchanger 3 through the four-way reversing valve 2 to condense, and then flows through the expansion valve 10 and the one-way valve 7 to enter the indoor heat exchanger 5. After the refrigerant evaporates and cools in the indoor heat exchanger 5, it returns to the compressor 1 through the four-way reversing valve 2. When the cooling and heating switch 6 selects the heating mode, the one-...

Abstract

The refrigerating and warming air conditioner incldues compressor, four-way selector valve, indoor and outdoot heat exchangers, refrigerating and warming switch and special throttling device, said throttling device includes non-return valve, capillary and/or expansion valve. It possesses several schemes to implement, and can be connected with indoor and outdoor heat exchanger respectively.

Description

technical field [0001] The invention relates to a heating and cooling air conditioner, in particular to a heating and cooling air conditioner with a throttling device with a new structure. technical background [0002] At present, the throttling device of the heating and cooling air conditioner is generally composed of a capillary tube, or a capillary tube and another capillary tube connected in parallel with a check valve in series. Capillary throttling, so that the air conditioner cannot achieve the best working conditions under both working conditions; although the latter can be adjusted by the check valve to make the air conditioner use different lengths in cooling and heating conditions. However, since the two capillaries have the same diameter, the secondary throttling cannot be better achieved during heating, and since the capillary connected in parallel with the check valve is directly connected to the indoor heat exchanger, the Under hot working conditions, the ref...
