Rain proof body avoids investment in machine rooms
The rain proof shell can meet the requirement of outdoor installation, which can make investment in machine
rooms unnecessary. The closed body can effectively reduce the operation noise of the unit, and the minimum
noise is only 56dB(A) without noise hazard.
Easily realize partitioned management
Cooling capacity is under flexible collocation, units in different areas and different floors can be control start/
stop seperately, people can use air conditioning in rental office when they work overtime.
Multiple cold and heat sources
Heat pump application can be realized through switch of external water lines; the system has higher
efficiency with utilization of waste heat and renewable energy, which realize energy saving and low carbon
operation. The entering water temperature has wide range, which can adopt different cold and heat sources.
Large capacity unit reduces installation
DAIKIN new modular water cooled chiller (heat pump) unit increases 40RT large capacity single module; the
number of unit can be reduced with large refrigeration capacity requirment; there is little installation, which
can greatly save the occupation area; it can realize the amount of 16 modular combination in the industry,
and there will be no waste for cooling capacity selection.
Convenient for capacity increase of the system
With increase of vistors flow rate and climate warming, the cold capacity of the existing central air-conditioning
of the building is not enough, UWL can be moved easily and the capacity increase of the cold capacity is
flexible, which has outstanding performance for the small scale capacity increase in the existing system.
Trinity function (optional)
UWL030B5 unit can choose heat recovery function with hot water generator built in; the unit has the trinity
function, which can realize heating and hot water simultaneously.
Primary pump variable flow design
After all compressors of the single modular of combination system are unloaded, the unit can output control
signal, and the water flow of the corresponding unit will be shut down; the requirement of the total water flow of
the system is reduced; automatic adjustment is made through the frequency conversion pump, so as to easily
realize primary pump variable flow, which can make the air conditioning system with 15% energy saving.
Higher efficiency of combining operation
In the area where it is hot in summer while cold in water, the cooling is long in summer while requirement for
heating is few in winter. UWL can be combined with air cooled heat pump; UWL water cooled modular heat
pump has high efficiency for cooling in summer, and the air cooled heat pump is mainly for heating. This air
conditioning system has high efficiency with economic investment.
Living hot water is made throughout the year
The highest hot water temprature of the condensor of UWL standard unit can reach 55 ºC, which can be used
to make domestic hot water throughout the year. Cooperated with the centralized machine, heat recovery or
cool recovery of the water system can be realized; domestic hot water can be made in transistion season;
the system is more stable and more efficient.
