Heating and Cooling Central Air Conditioning Station for University
Brief introduction
Air source heat pump(ASHP)can achieve summer cooling and winter
heating through the “handling” of thermal energy. Heat pump heating
and cooling is the extension and development of air conditioning
technology, and compared with ordinary air conditioners, it adapts
to a wider range of ambient temperatures, and the effect of heating
and cooling is better.
It could be connected in parallel and become a air conditioning
central station, providing air conditioning for several buildings.
Features of ASHP
1. Energy efficient
The energy efficiency can reach 4 times of electric heating, saving
operating costs.
2. Multi-purpose machine
The multi-function unit is configured according to user
requirements for heating, cooling and hot water.
3. Flexible configuration
Flexible radiators, fan coils, floor heating and other terminals
can be flexibly configured according to customer needs, which is
convenient for customers.
4. Easy to install
The unit is quick and easy to install and is not subject to
installation restrictions.

Yushen ASHPs
- Jet Boost compressor, high efficient and environmental-friendly,
even in -25C can work in high COP
- Fan of heat exchanger is big diameter Jagged type, which increase
the air flow tangent length when air going through fans, reduce
noise; When the air volume is increased, the heat exchanger is more
evenly.
- Multi-throttle channel design is accurate.
Multiple energy-saving devices in a single system, precise control
of refrigerant flow, enabling the unit to maximize heat/cooling
capacity and maximum energy efficiency in various working
environments, reducing operating costs
- The water side shell and tube heat exchanger have high efficiency
and reliability.
The industry's leading refrigerant distribution technology can
effectively improve the uniformity of gas-liquid two-phase fluid
distribution into heat transfer tubes, improve the utilization of
heat exchange tubes, and achieve efficient heat transfer.
- Large-area hydrophilic aluminum heat exchangers increase the heat
production.
The four-row tube V-shaped arrangement has high heat exchange
efficiency and uniform wind speed distribution.
It adopts 9.52*0.35 internal thread high-efficiency heat exchange
copper tube and 3.1mm large-format hydrophilic aluminum fins with
better hydrophobicity; it improves the operating efficiency during
frosting and reduces the number of defrosting.
The optimized long flow path design and wide expansion of the
expansion throttle ensure uniform distribution of refrigerant in
low temperature environments. Ensure even frosting, complete
defrosting, strong heating and efficient operation
