How to use Air Source Heat Pump for Underfloor Heating

Air source heat pump with underfloor heating is an advanced way to use heat energy in the air for heating. It converts low-grade heat energy in the air into high-temperature heat energy through air source heat pump technology, and then heats the ground through hot water circulation, thereby achieving indoor heating.

The working principle of air source heat pump with underfloor heating is as follows:

1. Heat energy conversion

The air source heat pump is mainly composed of compressor, evaporator, condenser and expansion valve. The compressor inhales low-temperature and low-pressure refrigerant, compresses it into high-temperature and high-pressure gas, and then dissipates heat through the condenser to become low-temperature and low-pressure liquid. In this process, the low-temperature and low-pressure liquid absorbs heat from the air in the evaporator and evaporates into high-temperature and high-pressure gas, and enters the compressor cycle again.

2. Heat transfer

The high-temperature and high-pressure gas releases heat in the condenser, heats the water in the water tank, and the water temperature continues to rise and is transported to the underfloor heating system through pipes. Hot water circulates in the underfloor heating pipes, heats the floor decoration layer, and heats the ground through ground radiation and convection heat transfer.

Advantages of air source heat pump with underfloor heating

1. Comfort and energy saving

Air source heat pump with underfloor heating is characterized by comfortable feeling, energy saving and high efficiency. It heats the entire floor evenly, avoiding the dryness caused by strong convection, and does not raise indoor dust, keeping the room clean. At the same time, because the heat is concentrated in the height of human body benefit, it saves 75% energy compared with traditional heating methods.

2. Installation and maintenance

There are two installation methods for air source heat pump with underfloor heating: dry and wet. The dry installation method uses a special plastic template to fix the water heating pipe, which is simple to install and has fast heat dissipation; the wet installation method is the traditional water heating type underfloor heating installation process, which is low in price and is the main process in the domestic market. During use, it is necessary to avoid high temperature work, drilling and nailing, etc., so as not to damage the underfloor heating pipe.

Air source heat pump with underfloor heating can not only provide comfortable heating effect, but also has the advantages of energy saving, environmental protection, and long service life. It is an ideal modern home heating solution.
