* Environmentally friendly: using seawater as a source of heat and cold, energy conversion, reducing the emission of CO2 and other atmospheric pollutants, avoiding cooling tower noise and mould pollution;
* Energy saving: the temperature conditions of the heat and cold source are better than the ambient air, with high operating efficiency;
* Capital saving: integrating heating, air conditioning and domestic hot water, enhancing economy;
* Stable: Relatively stable water temperature conditions, with a much smaller fluctuation range than air temperature variations, which makes operation reliable and stable;
* Flexible: the unit is optional in various forms, and the decentralized water fan can be used for air conditioning, heating and four controls at the same time;
* Aesthetic: Compared with air-cooled heat pump, there is no need for outdoor units to ensure the beauty of the building facade ;
