Abstract

The invention discloses a heat pump condensate water recycling system and a control method thereof. The heat pump condensate water recycling system comprises a heat pump system, a condensate water heat preservation water tank and a heat water heat preservation water tank; the heat pump system comprises a water receiving tray for collecting condensate water and a heat exchanger; the condensate water heat preservation water tank is connected with each of the water receiving tray and the heat water heat preservation water tank; the heat water heat preservation water tank is provided with a circulating water outlet, a circulating water inlet and a water replenishing pipe connector which is connected with a water replenishing pipe; the circulating water outlet is connected with a water inlet ofthe heat exchanger; and the circulating water inlet is connected with a water outlet of the heat exchanger. According to the heat pump condensate water recycling system disclosed by the invention, condensate water can be effectively recycled, and water resource is saved; and according to the control method for the heat pump condensate water recycling system disclosed by the invention, priority control of condensate water replenishing and tap water replenishing can be realized.

Description

technical field [0001] The invention relates to the field of heat pumps, in particular to a heat pump condensed water recycling system. In addition, the present invention also relates to a control method of the above-mentioned heat pump condensed water recycling system. Background technique [0002] During the heating process of the heat pump water heater, the finned heat exchanger will continuously generate condensed water. In the prior art, the condensed water is usually directly removed, resulting in waste of condensed water. If the condensed water is recycled and used as domestic water, water resources can be effectively saved. Therefore, it is necessary to design a heat pump condensed water recycling system to recycle the condensed water. Contents of the invention [0003] The present invention aims to provide a heat pump condensed water recycling system and its control method to solve the technical problem of energy waste caused by direct draining of condensed wate...
