Abstract

The invention discloses a heat pump air conditioner and a control method thereof, belongs to field of air conditioners and control methods thereof and aims at solving the problem that existing heat pump systems which are provided with radiation tail ends and heat convection tail ends simultaneously are low in energy efficiency. The heat pump air conditioner comprises a first compressor, a four-way valve, a draft fan heat convection tail end component and a first heat exchanger, the end A of the four-way valve is communicated with the outlet end of the first compressor, the end B of the four-way valve is communicated with the first end of the first heat exchanger, the end C of the four-way valve is communicated with the inlet end of the first compressor, and the end D of the four-way valve is communicated with the first end of the draft fan heat convection tail end component; the second end of the draft fan heat convection tail end component is communicated with the second end of the first heat exchanger; the heat pump air conditioner further comprises a second compressor and a radiation tail end component which are communicated with each other. By means of the heat pump air conditioner and the control method thereof, the different requirements for heating temperatures of a radiation tail end and a heat convection tail end are satisfied.

Description

technical field [0001] The invention relates to the field of refrigeration and heating equipment, in particular to a heat pump air conditioner and a control method for the heat pump air conditioner. Background technique [0002] The heating end of the heat pump is mainly divided into the radiation end (such as floor heating) and the fan convection heat exchange end. The radiant end has high comfort, but the radiant end used for heating is usually not suitable as the cooling end; the fan convection end can provide both heating and cooling, but the comfort is poor. In order to meet the cooling demand in summer, homes that use radiant end heating usually need to be equipped with fan convection heat exchange ends. Therefore, the convection end of the fan can be used as a supplement to the heating of the radiant end while heating the room. [0003] However, the heating temperature requirements of the radiant end and the convective heat exchange end are not consistent. Existing...
