1. Ground source heat pump technology system
The energy can be directly extracted from the shallow normal temperature soil by burying vertical pipe, horizontal pipe or throwing pipe to the surface water. In winter, the geothermal energy will be transferred to the buildings that need heating, and in summer, the heat in the buildings will be transferred to the surface shallow layer through the heat pump unit.
Compared with other forms of heating and cooling equipment, energy saving is very obvious; compared with the traditional air source heat pump, the ground source heat pump takes more energy, and solves the social problems such as the rapid depletion of fossil fuel and the environmental pollution caused by the consumption of fossil fuel, which is the real sense of energy conservation and environmental protection.
2. Radiant cooling and heating system of concrete ceiling
Through the evenly distributed water pipe embedded in the concrete floor, the normal temperature water is used as the cooling and heating medium for cooling and heating. In summer, the water supply temperature is about 20 ℃, and the return water temperature is about 26 ℃; in winter, the water supply temperature is about 28 ℃, and the return water temperature is about 20 ℃. The temperature difference heats or refrigerates the concrete floor, and then conducts heat transfer by radiation through the floor to adjust the indoor temperature.
The system has uniform temperature distribution, no mechanical rotating parts in the room, little difference between radiation temperature and air temperature, no sense of blowing, clean air, quiet and noiseless, and does not occupy the indoor space.
3. Healthy fresh air system
The fresh air after multistage treatment such as dedusting, disinfection and dehumidification shall be sent out from the ground skirting or under the window at a speed of less than 0.2 M / s and slightly lower than the indoor temperature, without noise and wind feeling.
Due to the low temperature and high density of the air supply layer, it will spread along the whole floor to form a "fresh air lake". It will be heated by human body and various other indoor heat sources, slowly rising together with the exhaust gas exhaled by the population, and discharged in an organized way through the upper exhaust outlet. The indoor air is fresh and pleasant with excellent quality.
