Embodiment Construction

[0031] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The invention provides an air-conditioning heat pump water heater and its antifreeze control method. When it is detected that the unit water system of the air-conditioning heat pump water heater is in the water circulation pipeline, the water temperature value at any component to be detected is lower than the corresponding set temperature value , start the auxiliary heating device at the corresponding component to increase the temperature of the component and the water temperature of the water system. Therefore, the present invention can solve the problem that the parts of the water system of the air-conditioning heat pump water heater freeze because of the low water temperature in the water system.

[0033] The present invention provides an air conditioner heat pump water heater 100, referring to figure 1 , t...

Abstract

The invention discloses an antifreezing control method for a hot water heater of an air conditioning heat pump. The method comprises the following steps of: collecting water temperature values of a water system of a unit of the hot water heater of the air conditioning heat pump at to-be-detected parts in a water circulating pipeline; and when the water temperature value at any one of the to-be-detected parts is smaller than a corresponding set temperature value, starting an auxiliary heating device at a corresponding part so as to raise the temperature of the part and the water temperature of the water system. The method disclosed by the invention can solve the problem that the hot water heater of the air conditioning heat pump is frozen as parts of the water system are frozen due to over-low water temperature in the water system.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner heat pump water heater and an antifreeze control method thereof. Background technique [0002] In Central China, North China and Northeast China, due to the low outdoor ambient temperature in winter, sometimes even below the freezing point of water. In such a low-temperature environment, if the unit of the air-conditioning heat pump water heater is not used for a long time in winter or the power is cut off for a short time due to various reasons, if the water in the water system of the unit is not discharged in time and the unit is on standby and the water system If the water does not flow, it will cause the internal parts of the water system of the unit (such as the water side heat exchanger, the water flow switch of the circulating water pump, the water supply system, the water pressure difference switch, etc.) to freeze and be damaged. [0003] In ...
