A direct-condensing air source heat pump floor heating system capable of supplying hot water

Abstract

The invention discloses a direct-condensing air source heat pump floor heating system capable of supplying hot water, which comprises a pipeline circuit equipped with a working fluid, an evaporator, a compressor, a hot water tank, a condensing and a throttle valve, the hot water tank and the throttle valve are connected through a pipeline equipped with working fluid, and a first electromagnetic valve is arranged on the connecting pipeline, and the connection between the condenser and the hot water tank A second solenoid valve is provided on the connecting pipeline, and the condenser is a geothermal heating pipe directly connected to the pipeline circuit. The invention not only saves heat exchangers and water pumps, avoids heat exchange loss, improves the system efficiency of floor heating, but also has the function of supplying hot water, greatly improving the utilization rate of the floor heating system.

Description

technical field [0001] The invention relates to the technical field of floor heating, in particular to a direct-condensing air source heat pump floor heating system capable of supplying hot water. Background technique [0002] Due to environmental pollution, serious energy waste and other reasons, the disadvantages of the central heating method using coal as the basic energy in my country are prominent, and it is bound to change to the heating method based on floor heating. Current floor heating systems are generally water heating systems powered by gas, oil or electricity. Compared with the heat pump method, there are the following main disadvantages: (1) In terms of energy consumption, the energy efficiency ratio of the direct method is always less than 1, while the energy efficiency ratio of the heat pump method can reach 3.0; (2) In terms of safety, the water and electricity of the heat pump method are separated, There will be no leaks, but there may be leaks in the dir...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing heat pump floor heating device, a heat exchanger is installed on the outside of the refrigerant in the floor heating pipeline, and a water pump is equipped for circulation. This structure has a large heat exchange loss, which affects the system efficiency of the floor heating; and this This structural form of floor heating cannot supply hot water to people while working in the winter heating season, nor can it supply hot water to people in summer when floor heating is not used, which greatly reduces the utilization rate of the floor heating system.
