摘要： Provided is an outdoor unit of an air conditioner, including: an outdoor heat exchanger that has a height longer than a width; and an outdoor blowing fan that is disposed above the outdoor heat exchanger and blows air upward from below the outdoor heat exchanger, in which the outdoor heat exchanger includes: a plurality of radiating fins that contacts air; a gap that is formed between the radiating fins; a louver fin that is cut in the radiating fin and then bent; and a cut-out area that is formed in the radiating fin and formed at a position where the louver fin is cut, the radiating fin includes: a first zone that is disposed above the outdoor heat exchanger and disposed close to the outdoor blowing fan; and a second zone that is located below the first zone, and an area LA1 of the louver fin in the first zone is formed to be larger than an area LA2 of the louver fin in the second zone.
The present disclosure has the advantage of uniformly forming air volumes in each zone of the heat exchanger in the vertical height direction by making the areas of the louver fins arranged in each zone different, even when the outdoor blowing fan is disposed to be biased upward.

摘要： A refrigeration apparatus, including a main circuit for a loop circulation of a main flow of refrigerant, the main circuit including a compressor, a condenser, an expansion valve and an evaporator. The refrigeration apparatus comprises a lubrication branch, for deriving a lubrication flow from the main flow for feeding the compressor for lubrication. The main circuit includes a low-temperature part, consisting in the evaporator, the compressor inlet, and any part of the main circuit between the evaporator and the compressor inlet. The lubrication branch further includes a subcooling heat exchanger, which is configured for enabling an exchange of heat between the lubrication flow circulating through the lubrication branch and the main flow of refrigerant circulating through the low-temperature part, so that the lubrication flow may be cooled by the main flow of refrigerant circulating through the low-temperature part, within the subcooling heat exchanger.

摘要： A heat exchanger including: rows of heat exchanging units that are superposed with one another in an air flow direction of the heat exchanger; and flat multi-hole tubes that extend from a first end toward a second of the heat exchanging units in a first direction in the heat exchanging units and that include gas-side flat multi-hole tubes. A refrigerant flows in the heat exchanging unit in the first direction. A number of the gas-side flat multi-hole tubes that are included in a front-most row heat exchanging unit on an airflow upstream side of the heat exchanger is less than a number of the gas-side flat multi-hole tubes included in a rear-most row heat exchanging unit on an airflow downstream side of the heat exchanger.

摘要： A flat tube for a heat exchanger has a tube body with an outer top and an outer bottom surface arranged opposite one another at a thickness of the tube body and two outer side surfaces arranged opposite one another at a width of the tube body and connecting the outer top and bottom surfaces. The tube body has a heat exchange portion extending along an extension direction, an angled portion extending along an transverse direction inclined relative to the extension direction, and a bent portion connecting the heat exchange portion to the angled portion. The angled portion is arranged at a distance from the heat exchange portion in an offset direction. The bent portion has a first end region facing the heat exchange portion with a first bend counter to the offset direction and a second end region facing the angled portion with a second bend in the offset direction.

摘要： An HVAC system includes an evaporator, a first sensor coupled to the evaporator at a first position, and a second sensor operably coupled to the evaporator at a second position. The first sensor monitors a first temperature of the refrigerant flowing in the evaporator at the first position, which is adjacent to the evaporator inlet. The second sensor monitors a second temperature of the refrigerant flowing in the evaporator at the second position, which is downstream from the first position. The system includes a controller, which receives a first signal corresponding to the first temperature and a second signal corresponding to the second temperature. The controller determines, based on the received signals, a temperature difference between the second temperature and the first temperature. In response to determining that the temperature difference is greater than a predefined threshold value, the controller determines that a loss of charge has occurred.
