Seawater source heat pump system
Advantages of the system

* 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 ;

Article 24 The state treasury establishes special funds for the development of renewable energy, which are used to support scientific and technological research, standard development and demonstration projects for the development and utilization of renewable energy.
Suitable applications
Various types of buildings in coastal areas, e.g. Dalian, Qingdao.
System principle

Discharge indoor heat in summer and use seawater to dissipate heat; draw heat from seawater to heat the room in winter.
1. Connected by plate heat exchanger: the heat exchanger adopts titanium plate detachable plate heat exchanger, which can be anti-corrosion and anti-biological adhesion, without being able to achieve good heat transfer effect and solve the corrosion problem of seawater to the equipment, and it is clear or easy to replace.
2. Seawater directly into the unit: the Mammoth water source heat pump unit, evaporator and condenser use copper-nickel alloy, good corrosion resistance, seawater can directly into the unit, because of the omission of plate exchange, for the unit into the water working conditions better.
