Title: REFRIGERATING HEAT PUMP TYPE FROST-FREE AIR CONDITIONER
Abstract:
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 and frequency conversion electric control module space, a frequency conversion electric control box (5), and a compressor (6). An induced air way (10) is disposed at an air outlet of the fan (11). The induced air way (10) 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 enters the compressor and frequency conversion electric control module space through the induced air way (10), 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 air conditioner has the characteristics: frost-free heating is implemented, heat dissipation and temperature reduction are performed on the compressor and a frequency conversion electric control module, the heating capacity is great, and the energy efficiency of the air conditioner is high.
