Problems solved by technology
[0003] When the air conditioner is heating, the refrigerant in the refrigerant circulation circuit exchanges heat with the outdoor heat exchanger, so that the surface temperature of the outdoor heat exchanger is low, and when the air is cold, condensation forms on the surface of the air conditioner outdoor unit. If the heater works in a low temperature environment for a long time, it will cause condensation and ice on the surface of the outdoor heat exchanger, which will reduce the performance of the outdoor heat exchanger

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0029] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0030] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses a refrigeration device and a control method thereof. The refrigeration device comprises a controller, a compressor, a four-way valve, an indoor heat exchanger and an outdoor heat exchanger, wherein the compressor, the four-way valve, the indoor heat exchanger and the outdoor heat exchanger are electrically connected with the controller; the compressor, the four-way valve, the indoor heat exchanger and the outdoor heat exchanger are communicated through a pipeline to form a refrigerant circulating loop, the indoor heat exchanger and the compressor are communicated through a pipeline to form a bypass branch which passes through the bottom of the outdoor heat exchanger, and the refrigeration device further comprises a throttling device electrically connected with the controller; the throttling device is mounted at the pipeline, between the indoor heat exchanger and the outdoor heat exchanger, of the bypass branch. Accordingly, the temperature of the bottom of the outdoor heat exchanger is higher than that of the top of the outdoor heat exchanger; due to the fact that the flowing speed of air on the top of the outdoor heat exchanger is high, frosting is avoided; due to the fact that the temperature of the bottom of the outdoor heat exchanger is high, condensation dropping to the bottom of the outdoor heat exchanger can be prevented from being frosted, and therefore the risk of bottom frosting of the outdoor heat exchanger is reduced.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration device and a control method thereof. Background technique [0002] Air conditioners are commonly used refrigeration equipment in daily life, including compressors, four-way valves, indoor heat exchangers and outdoor heat exchangers, compressors, four-way valves, indoor heat exchangers and outdoor heat exchangers The heater is connected through pipelines to form a refrigerant circulation loop for the refrigerant in the compressor to flow. [0003] When the air conditioner is heating, the refrigerant in the refrigerant circulation circuit exchanges heat with the outdoor heat exchanger, so that the surface temperature of the outdoor heat exchanger is low, and when the air is cold, condensation forms on the surface of the air conditioner outdoor unit. If the heater works in a low temperature environment for a long time, it will cause condensation and ice on the...
