Floor heating system with variable-frequency air source heat pump

Abstract

The invention discloses a floor heating system with a variable-frequency air source heat pump. The floor heating system is characterized by comprising a variable-frequency air source heat pump host machine, a variable-frequency internal machine and a radiant floor heating system arranged below indoor floor, wherein the variable-frequency air source heat pump host machine internally comprises a variable-frequency compressor and variable-frequency electric control equipment, and a refrigerant backflow connector and a refrigerant output connector are arranged on the variable-frequency air source heat pump host machine; the radiant floor heating system comprises a water pipe, the water pipe is arranged at the bottom of the floor and arranged into an S shape, a water inlet of the S-shaped water pipe is connected with a floor heating water supply pipe, and a water outlet of the S-shaped water pipe is connected with a floor heating water return pipe; a plate heat exchanger, a water pump and indoor electric control equipment are arranged on the variable-frequency internal machine. The floor heating system with the air source heat pump has the advantages of super-high energy efficiency, good environment friendliness, high safety, comfort, the capability of realizing intelligent control and the like.

Description

technical field [0001] The invention relates to the field of heat pumps, in particular to a frequency conversion air source heat pump floor heating system. Background technique [0002] In recent years, environmental pollution has become increasingly serious. In order to protect the environment, the use of coal stoves for heating has been restricted in cold areas. The use of fuel oil or gas is not only expensive, but also has harmful gas emissions. At the same time, there are certain safety issues. Direct heating with electricity It can meet the cleaning requirements, but the price is high and it is not energy-saving. [0003] Floor heating is a new heating method developed in recent years. Floor heating mainly uses ground radiation. It heats evenly, which is a heating requirement with high comfort and energy saving. Due to the requirements of human hygiene, the surface temperature of the heating device should not be higher than 24°C. Therefore, it is more appropriate t...

Problems solved by technology

This year, the use of low-temperature hot water for bottom radiant heating has developed rapidly. Most of the heating sources are water source heat pumps. Although they meet the requirements of environmental protection and energy saving, they need to use underground resources and are limited.

At present, air source heat pump units are also used for floor heating, but fixed frequency compressors are commonly used, which are prone to overheating or insufficient temperature
