The water-cooled packaged unit is a central air-conditioning unit that uses cooling water as the cold source and uses refrigerant to produce cold capacity. The structure integrates the compressor, evaporator, condenser, and throttle components to directly output cold air. Water-cooled cabinets ,water cooled packaged units are usually suitable for places where the summer is hot and the space requires a large amount of air; the water-cooled cabinets can be individually controlled or multiple centralized control methods can be selected according to customer needs. The water cooler has a wide range of applications, and can be applied to shopping malls, hotels, factories, villas, commercial housing, office buildings, shops, hospitals and other places.

Description:
1. Water source heat pump unit has higher efficiency than air cooled heat pump unit, reduce power consumption, new popular unit;
2. No need machine room, lower investment cost;
3. The heat pump unit can be connected to user's ammeter and the user will only responsible for own air conditioning and heating charges, charge as per family.
4. Copper tubes with aluminium fins evaporator, optional hydrophilic aluminium fins, copper fins.
5. Condenser: shell and tube type, high heat exchange efficiency, could be cleaned through mechanical or chemical method, more easier for maintainance.
6. Microcomputer controller: simple interface, adjust temperature automatically, convenient for operation and easy for maintainance.
7. Refrigerant available: R22,R407C, R410A.
Applications:
- Boiler/cooling tower water loop system, lower requirement of design and techniques, less investment and shortest construction period.
- Underground water open loop system, underground water will be directly used to provide cooling or heating source. The advantage is enjoying constant temperature, higher efficiency, mainly suitable for areas where near to water pools , etc.
- Surface water closed loop system, this system suitable for buildings adjacent to large area natural water source, like lake, river, etc.
- Ground source heat pump closed loop system. This system requires to drill holes under ground and bury plastic composite heat exchange pipes, require high technology of installation and higher investment, maintainance is more difficult.
