Abstract

The invention discloses a heat pump unit and a control method thereof. The heat pump unit comprises a compressor, underfloor heating devices, radiators, a first water pump and a second water pump, wherein a water outlet of the first water pump is connected with water inlets of the radiators and a water inlet of the second water pump; a water outlet of the second water pump is connected with water inlets of the underfloor heating devices; the radiators and the underfloor heating devices are arranged in N rooms respectively. The control method comprises the following steps: acquiring a current outdoor ambient temperature, and acquiring working states of the underfloor heating devices and the radiators; according to the current outdoor ambient temperature, and the working states of the underfloor heating devices and the radiators, acquiring a set outlet water temperature of the heat pump unit; according to the set outlet water temperature of the heat pump unit, and the working states of the underfloor heating devices and the radiators, controlling the compressor, the first water pump and the second water pump so as to achieve an energy-saving purpose.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method of a heat pump unit and a heat pump unit. Background technique [0002] At present, the hot and cold water machines are all started and stopped according to the outlet water temperature. In actual use, floor heating and radiators may be included at the same time, but floor heating and radiators require different cooling or heating water temperatures. If they are set to the same outlet water temperature, resources may be wasted. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a control method of a heat pump unit, by determining the outlet water set temperature of the heat pump unit according to different ambient temperatures, floor heating and radiator working conditions, so as to co...
