In one embodiment, the heat exchanger is a plate heat exchanger, but is not so limited.
In one embodiment, a refrigerant flow adjusting device is arranged in a system pipeline from the heat exchanger to the indoor unit.
Preferably, the refrigerant flow rate adjusting device is an electronic expansion valve, but is not limited thereto.
The apparatus for transferring a cool source of the present invention may further include a control unit. The control unit is used for controlling the effective operation of the whole refrigeration system.
The beneficial technical effects of the invention comprise:
(1) the separated gravity heat pipe technology is adopted for conveying the outdoor cold source to the indoor, no mechanical power is used, zero energy consumption is realized, and more energy is saved.
(2) The outdoor unit and the indoor unit can be arranged in long distance, and can exceed 200 meters in engineering and even have longer distance.
(3) The overall energy efficiency ratio is high.
Drawings
FIG. 1 is a schematic diagram of an apparatus for transferring a cooling source according to the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings. It should be understood that the embodiments of the present invention described in the drawings are illustrative of the invention and are not to be construed as limiting the invention.
