Common classification of air-energy heat pump heating system

By structural form: integral type, split typeIntegral type: All the fluorine system components of the unit are concentrated in one chassis. For some special models, the water tank will also be required to be built-in.

• Split type: The fluorine system of the unit needs to be composed of at least 2 boxes.
• By heating method: fluorine circulation type, water circulation type, one-time heating type
• Fluorine circulation: During the heating process, the heated medium (water) is in a natural convection state, and only fluorine circulates in the system.
The fluorine cycle can be divided into: inner coil and outer coil
Features of the inner coil: Water and fluorine can directly exchange heat through the copper tube, and the heat exchange efficiency is relatively high, but because the copper tube is immersed in water, the life is greatly affected by the water quality.
Features of the outer coil: The heat exchange between water and fluorine needs to pass through the water tank wall and copper tube, and the heat exchange efficiency is relatively low, but the protection of the system is better.
• Water circulation: During the heating process, the heated medium (water) and the heating medium (fluorine) use counter-current heat exchange in the heat exchanger, and reach the set temperature after multiple cycles, that is, water circulation.
• One-time heating: During the heating process, the heated medium (water) and the heating medium (fluorine) use counter-current heat exchange in the heat exchanger, and reach the set temperature directly at one time, that is, direct heating.

According to the form of heat source: air source, water/ground source, dual source (air/ground)
Air source is divided into: normal temperature air source, low temperature air source Water/ground source is divided into: water source heat pump, water ring heat pump, soil source (ground source) heat pump, waste heat source heat pump, etc.
According to the application method: heat pump water heater, heating heat pump, high temperature heat pump, trigeneration heat pump
Others: variable frequency heat pump, drying heat pump, etc.
