Heating/air-conditioning system has fan below heat exchangers so cold heat exchanger end face subjected to air flow is at at least 90, preferably between 150, 180 degrees, to air flow from fan spiral

摘要

The system has an air guide housing, a fan, a cold heat exchanger, a hot heat exchanger, air outlets, an external air inlet channel and a fan outlet channel close to and with an opposed flow direction to the external inlet channel. The fan is below the heat exchangers so the cold heat exchanger end face subjected to air flow is at an angle of at least 90, preferably between 150 and 180 degrees, to the direction of air flow from the fan spiral. The system has an air guide housing (1), a fan (2), a cold heat exchanger (6), a hot heat exchanger (7), air outlets (10-13), an external air inlet channel (8) and a fan outlet channel (9) close to and with an opposed flow direction to the external inlet channel. The fan is below the heat exchangers so that the end face (14) of the cold heat exchanger subjected to the air flow is at an angle of at least 90, preferably between 150 and 180 degrees, to the direction of air flow emanating from the fan spiral.
