Abstract

The invention relates to operation methods of heat pump heating devices, in particular to an operation method of a closed-loop self-source heat pump unit, wherein the operation method is designed anewaccording to the invention patent (ZL201110061250.2). The closed-loop self-source heat pump unit has the characteristics that the heating capacity is high, the closed-loop self-source heat pump unitis not affected by external environments such as the water and air temperature conditions, the weight of the unit is reduced, and the manufacturing cost is reduced. In order to solve the problems thatin the winter of extremely cold areas of north and south latitudes of 40 degrees or over, the temperatures of groundwater and air are very low, thus the heating capacity of a water source and air source heat pump unit is weakened, and the water source and air source heat pump unit cannot operate and be used, the closed-loop self-source heat pump unit and the operation method are designed and canbe widely used for heating in the winter of the extremely cold areas of north and south latitudes of 40 degrees or over.

Description

technical field [0001] The invention relates to an operating method of a heat pump heating device, in particular to an operating method of a closed-loop self-source heat pump unit. Background technique [0002] Water source and air source heat pump units have high thermal energy utilization rate and high heat generation coefficient (coefficient of performance), so using water source and air source heat pump units for heating can save electricity and fuel. However, in winter in extremely cold regions above 40 degrees north and south latitudes, due to the very low temperature of groundwater and air, the heating capacity of water source and air source heat pump units is weakened and cannot be used. In order to solve this problem, the operation method of a closed-loop self-source heat pump unit designed by the present invention is newly designed according to the invention patent (ZL 2011 1 0061250.2), which has strong heating capacity and is not affected by external water, air t...
