Abstract

The invention discloses a full-indoor air conditioner for introducing fresh air in a cold region. The full-indoor air conditioner comprises a fresh air opening, an air inlet, an air supply fan, a first exhaust opening, a first exhaust fan, a ceiling air pipe, an indoor heat exchanger, a compressor, a four-way reversing valve, a throttling device, an in-pipe heat exchanger and a second exhaust opening. The in-pipe heat exchanger, the throttling device, the indoor heat exchanger and the four-way reversing valve are sequentially connected to constitute a heat pump circulating system. The compressor is further connected with the four-way reversing valve. The ceiling air pipe is arranged in an air conditioner room, and the two ends of the ceiling air pipe are correspondingly connected with theair inlet and the second exhaust opening which are formed outside the air conditioner room. The air inlet is internally provided with the air supply fan. The compressor, the four-way reversing valve and the in-pipe heat exchanger are arranged in a heat exchange pipe section of the ceiling air pipe. Compared with the prior art, the full-indoor air conditioner can be simple in structure, still operates efficiently in the cold region at the temperature of minus 15 DEG C, and is not liable to frost and low in cost.

Description

【Technical field】 [0001] The invention relates to the technical field of heating, ventilating and air-conditioning, in particular to an all-indoor air conditioner suitable for introducing fresh air in cold regions. 【Background technique】 [0002] According to meteorological data, air source heat pumps must operate efficiently and reliably for a long time in an atmospheric environment of -15°C in order to meet the winter heating needs of cold regions in my country. At present, the common air source heat pump hot water units in the southern market cannot be applied in the cold regions of my country. decline. A system with the same number of horses, working in a low temperature environment, exhibits a smaller heating capacity. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a whole indoor air conditioner for introducing fresh air in cold areas, which can be simple in structure, can still operate effi...
