Four dimensions to measure environmental comfort
Temperature: More stable temperature (small temperature difference, small wind temperature difference, wind temperature closer to the set temperature)
2. Humidity: Not dry, not damp, water-nourished (no dry mouth in summer, no stuffy in winter)
3. Airflow Organization: Compliant with air operation principles to enhance comfort
(For summer air conditioning cooling, cool air sinks; for winter ground heating, warm air rises;)
(quieter: Air conditioning cooling is quiet and gentle, underfloor heating heating is peaceful and noiseless)
4. Cleanliness: Healthier (no dust in winter with radiant heating).

First-Generation Air Conditioner: Window Type
Cannot heat; only cools.
2. No distinction between indoor and outdoor units.
3. Inefficient single-pass heat exchange system, poor comfort level.
4. Airflow enters and exits at the same point, poor ventilation method, resulting in low comfort.
5. High operating noise.

Second-Generation Air Conditioners: Wall-Mounted Units, Split Systems, Ducted Units
Cooling, heating.
2. Separate outdoor and indoor units for installation, one-to-one configuration.
3. Multiple outdoor locations available
4. Wall-mounted and cabinet air conditioners take up indoor space.
5. Indoor single heat exchange system lacks comfort.

Third-Generation Air Conditioner: Fluorine Machine Central Air Conditioning
Cooling and heating
2. Multi-split outdoor units
3. Poor comfort in one-time heat exchange system indoors;
The principles of the above three generations of air conditioners are the same; they all involve the refrigerant entering the indoor unit directly to undergo a single heat exchange with the indoor air, achieving indoor heating and cooling with relatively poor comfort: significant impact on humidity (drying), and a single function (cannot be used for direct ground heating).

4th Generation Air Conditioner: Air Source Heat Pump Central Heating and Air Conditioning System

Reasons for Choosing an Air-Source Heat Pump

Boiler heating is not needed; it's superior to boiler heating.
There is rarely centralized heating in the Yangtze River Delta region; traditional wall-hung boilers and underfloor heating are constrained by gas purchase restrictions or tiered gas pricing. Utilizing an air-source heat pump, install an extremely comfortable underfloor heating system for a more comfortable heating experience.The advantages of radiant heating are detailed in the radiant heating system introduction).
2. Delivers a gentle breeze with non-dry air:
The air-source heat pump air conditioner overcomes the drawbacks of refrigeration with central air conditioning using Freon, providing a more gentle and comfortable airflow that doesn't make the indoor air feel dry.
4. More cost-effective investment, more energy-efficient operation
Initial investment saves the cost of the wall-hung boiler and subsequent maintenance expenses.
The two-in-one air-source heat pump system offers significant cost savings compared to using a separate fluorine machine central air conditioning unit for cooling and a gas wall-mounted boiler for heating.
The return water temperature for heating is lower than the water temperature for wall-hung boilers, making it less prone to scaling and easier to clean.
4. Separate hot water heating systems, no interference
Independent Hot Water System; does not affect the quality of heating.
