The invention belongs to the technical field of low-temperature air energy heat pumps, and particularly relates to an ultralow-temperature air energy heat pump unit. In allusion to the problem that an air inlet in the unit is easy to freeze quickly due to abnormal cold outside air in a low-temperature area, the invention proposes the following scheme: the ultralow-temperature air energy heat pump unit comprises a unit shell and a heat preservation water tank, a circulating water pipe is arranged between the unit shell and the heat preservation water tank, a circulating pump is arranged in the circulating water pipe, a temperature sensing line is wound on the circumferential inner wall of the heat preservation water tank, a controller is arranged at the end, which is away from the heat preservation water tank, of the temperature sensing line, a control line is connected between the control end of the controller and the unit shell, water level warning devices distributed at equal intervals are arranged on the front surface of the heat preservation water tank, the top end of the heat preservation water tank is communicated with a water inlet pipe, and the middle of the water inlet pipe is communicated with a water mixing valve. According to the invention, related heating components in the unit shell can be adjusted according to the arrangement of the temperature sensing line to adjust the temperature, so that the response speed and the accuracy of temperature control are improved.
Description
technical field [0001] The invention relates to the technical field of low-temperature air energy heat pumps, in particular to an ultra-low temperature air energy heat pump unit. Background technique [0002] With the support and encouragement of various policies, air source heat pumps have achieved rapid development and ushered in a new period of development opportunities. The operating environment temperature of ordinary air source heat pump units is generally above 0°C. In areas with cold climates, ordinary air source heat pumps cannot operate normally. Moreover, under the working conditions of heating and hot water production, since the outdoor side heat exchanger is placed outdoors, when the outdoor ambient temperature is low and the air contains a certain humidity, the outdoor heat exchanger is prone to frost, which will Seriously affect the performance of the unit, or even shut down. In order to solve the problem of frosting, some heat pumps are equipped with specia...
