Throw pipe type river/river/lake water source heat pump system
Advantages of the system

* Environmental protection: using lake water as the cooling and heating source for energy conversion, reducing the emission of CO2 and other atmospheric pollutants, avoiding cooling tower noise and mould pollution;
* Energy saving: cooling and heating source temperature conditions are better than 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 pumps, there is no need for an outdoor unit, which ensures the aesthetics of the building facade;

Standard or code reference
Design Standard for Energy Efficiency of Public Buildings" GB50189-2005, p18, "Air conditioning and heating sources of heat and cold", Article 5; When natural water resources or geothermal heat are available, it is appropriate to use water (ground) source heat pump cooling and heating technology.
Suitable applications
Areas with abundant surface water bodies.
System principle

Closed cycle, river/river/lake water does not enter the unit directly, no special requirements for water quality.
