Problems solved by technology

[0010] But there is such a problem in the outdoor unit of the one-to-many air conditioner of prior art: when it is below a certain temperature outside the temperature, the temperature difference between the refrigerant and the outdoor air in the outdoor heat exchanger 104 will appear little or even When the temperature of the outdoor air is lower than the temperature of the refrigerant, the outdoor heat exchanger 104 cannot be defrosted sufficiently at this time, and the outdoor heat exchanger 104 is frozen and accumulated, so the heating efficiency will drop

Abstract

The present invention relates to an outdoor machine of heat pump type one-driving-many air conditioner. It includes machine box, compressor placed in the interior of machine box, outdoor heat exchanger which is placed in the interior of machine box and is used for making refrigerant be heat-exchanged with exterior air, and heater which is placed in the interior of machine box and is used for providing warm air fox interior of machine box wheen the indoor temperature is below defined temperature and defrosting the outdoor heat exchanger.

Description

technical field [0001] The invention relates to an outdoor unit of an air conditioner. In particular, it relates to an outdoor unit of a heat pump type one-to-multiple air conditioner in which a heater is arranged on the lower side of an outdoor heat exchanger and the heater is automatically operated when the outdoor temperature is below zero. Background technique [0002] figure 1 It is a schematic diagram of a one-to-many air conditioner in the prior art. [0003] The structure of the one-to-many air conditioner in the prior art is that one outdoor unit 100 is connected to a plurality of indoor units 110 through refrigerant pipes, which is a kind of provision for each indoor unit 110 provided with the indoor unit 110 along with the flow direction of the refrigerant. Air-conditioning or heating device. [0004] The outdoor unit 100 is composed of the following structure: a compressor 102 that compresses the refrigerant at high temperature and high pressure, an outdoor he...
