Water system energy-saving control
Control system of UWL-B5 series units can intelligently output the control signals of air conditioning chilled
water pump, cooling water pump and cooling tower, and can control start and stop of the cooling tower based
on the temperature of the cooling water. After compressors of all units deloading, the unit will automatically
shut down the cooling water pump, and can effectively decrease energy consumption of the system during
transitions season or running at low load. The unit has two-way valve interlocking function, when all fan coils
are shut down, the unit will shut down the pumps and cooling tower and then enter standby status.
Low carbon and environment friendly
Cooling and heating function can be realized through different system design schemes with reusable energy
as the heat exchange system, the unit can be more efficient and energy-saving. R410A environmental
friendly refrigerant is adopted without limit on use term, which does not destroy the ozone layer.
Double backup operation makes double improvement of reliability
There are 3 or 4 sets of compressors in every single unit; failure of a single compressor does not affect
operation of theunit; failure of unit module does not affect operation of the combination system. During use
through combination it doesn't need another one master unit for standby, so that the air conditioning system
is safer and more economic in investment. Double backup operation can make double increase in reliability
of the air conditioning system; the air conditioning system may continue to run before maintenance personnel
arrive, which can make maintenance and repair easy in remote areas.
High efciency shell and tube heat exchanger for condenser and evaporator
Shell and tube heat exchanger with large pipe diameter is adopted for evaporator and condenser, which has
high tolerance on water quality, while the unit has strong ability to resist lth blockage. Internal thread nned
copper tubes are adopted inside the shell and tube heat exchanger, which can increase the effective heat
transfer surface; turbulent ow type water ow process design can delay internal scale and increase thermal
efciency. Using multiple sets of electronic expansion valve for precision throttling can make precise dynamic
throttling when water temperature condition changes,and it can stably control target superheat of the unit, so
as to keep safe and efcient operation of the unit.
Double balance operation extends service life of the overall unit
Compressors in single unit have balance operation time function; and the operation time among modules can
be balanced during multiple module combination; double balance operation design can reduce the rate of
failure, which can extend the service life of the overall unit.
Self-protection and self-diagnosis function
The unit has water over-temperature protection, low water ow protection, protection for compressor frequent
start-stop, refrigerant high/low pressure protection, etc.; when the water temperature is too low in winter, the
unit enter anti-freezing operation protection automatic by starting up water pump. When failure occurs, self-
diagnosis function can rapidly and accurately show the cause of the problem; acousto-optic code display can
assist rapid troubleshooting.
Compact and exible air conditioning solution
The compact modular body can be moved via good elevator without large hoisting equipment, so that it can
be easily moved into the existing water cooling machine room, and can enter the basement for replacement
of old machine without dismantling the existing construction during reform of some old projects.
Features

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 exible collocation, units in different areas and different oors can be control start/
stop seperately, people can use air conditioning in rental ofce 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
efciency 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 ow 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
exible, 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 ow design
After all compressors of the single modular of combination system are unloaded, the unit can output control
signal, and the water ow of the corresponding unit will be shut down; the requirement of the total water ow of
the system is reduced; automatic adjustment is made through the frequency conversion pump, so as to easily
realize primary pump variable ow, which can make the air conditioning system with 15% energy saving.
Higher efciency 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 efciency for cooling in summer, and the air cooled heat pump is mainly for heating. This air
conditioning system has high efciency 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 efcient.
