Title: OUTDOOR UNIT FOR REFRIGERATING HEAT PUMP TYPE FROST-FREE AIR CONDITIONER
Abstract:
An outdoor unit for a refrigerating heat pump type frost-free air conditioner comprises an outdoor unit housing (4), an evaporator (12), a fan (11), a middle partition plate (9), a compressor (6), a frequency conversion electric control box (5), and a compressor and frequency conversion electric control module space. An air inlet of an induced air way is disposed at an air outlet of the fan (11), and a plane formed by the air outlet of the fan (11) serves as a projection plane. A projection of a plane formed by the air inlet of the induced air way on the projection plane and a projection of the plane formed by the air outlet of the fan (11) on the projection plane form an overlapped surface. The induced air way penetrates through the middle partition plate (9) to communicate with the compressor and frequency conversion electric control module space. An air collection hood (3) is disposed on the outdoor unit housing (4) of the compressor and frequency conversion electric control module space. The air collection hood (3) is connected to a heating air supply air-pipe (1). Air discharged by the fan (11) enters the compressor and frequency conversion electric control module space through the induced air way, flows through the compressor (6) and the frequency conversion electric control box (5), then enters the air collection hood (3) and is conveyed to an air inlet side of the evaporator (12) through the heating air supply air-pipe (1), and flows out. The outdoor unit has the characteristics: frost-free heating is implemented, heat dissipation and temperature reduction are performed on the compressor (6) and a frequency conversion electric control module, the heating capacity is great and the energy efficiency of the air conditioner is high.
