Problems solved by technology

In addition, most of the current air-conditioning ends are fan-coil systems, which consume a lot of energy, and the fan noise is loud, occupying indoor space and affecting interior decoration. In winter, when heating, it is easy to cause indoor air to be dry, and it is easy to cause cross-infection of bacteria in the air. Poor air quality and low comfort in the room

On the one hand, the temperature of the inlet and outlet water on the use side is 12-7°C during traditional cooling, and the temperature of the inlet and outlet water on the use side is 40-45°C during heating, the evaporation temperature is low, the condensation temperature is high, and the power consumption is large
