Heat-pump-technology-based energy-saving type shower system under outdoor low-temperature environment

Abstract

The present invention relates to a heat-pump-technology-based energy-saving type shower system under an outdoor low-temperature environment. The system comprises an undressing room, a shower room, a dressing room and a power room, wherein the shower room is provided with a plurality of shower nozzles, with a water accumulation pool being disposed on the ground of the shower room; the power room is provided with a main power supply petrol generating set, a car battery, a PLC industrial control machine, an air-source heat pump heat extraction subsystem, an electromagnetic heating subsystem, a water-water heat exchanger, a heat storage water tank, a cold water tank and an air-water heat exchanger; the main power supply petrol generating set is connected individually with the air-source heat pump heat extraction subsystem and the air-water heat exchanger; the electromagnetic heating subsystem is connected with the heat storage water tank; the water-water heat exchanger is connected with a shower waste water collection tank, the cold water tank and the heat storage water tank; the shower nozzles are connected with the heat storage water tank and the cold water tank; the water accumulation pool is connected with the shower waste water collection tank; the heat storage water tank is connected with the air-water heat exchanger; and the assemblies are all connected with the PLC industrial control machine. With adoption of the system provided by the present invention, outdoor shower requirements can be achieved, and energy conservation and environment protection aims are also achieved.

Description

technical field [0001] The invention relates to a shower system, in particular to an energy-saving shower system in an outdoor low-temperature environment based on heat pump technology. Background technique [0002] In the 21st century, environmental protection and energy issues have attracted the attention of countries all over the world. Heat pump technology began to move from the laboratory to the market in the United States and other developed countries in the 1990s. It has been widely used in China and has developed into a fully mature, advanced, energy-saving and environmentally friendly HVAC product. It uses air, water, etc. as the heat source, adopts the reverse Carnot principle, absorbs the heat in the external air and water source through the evaporation of the refrigerant, and transfers the absorbed heat to the water on the user side through the refrigerant cycle, so that the water temperature on the user side The energy efficiency ratio (cop) is generally 2~8. ...

Problems solved by technology

At the same time, due to the sharp decrease in refrigerant evaporation, the possibility of liquid shock caused by excessive liquid return is greatly increased, which will cause unstable operation of the unit, resulting in a reduction in the heating capacity of the heat pump system

[0005] The second is the problem of evaporator frosting
