Fresh Air Handling Unit With Plate Type Aluminum Core Heat Exchanger

Product Overview

Description

Fresh Air Handling Unit With Plate Type Aluminum Core Heat Exchanger

 

Features:

1.  HAX series air handling units with heat recovery are with heat pump built in, world famous hermetic scroll compressor(Hitachi, copeland);

2.  HAX series air handling units with heat recovery can supply high air quality: introduce fresh air from outside and discharge polluted air to the outside;

3.  HAX series air handling units with heat recovery all are total heat recovery: the low temperature and humidity discharged air is used to cool the condenser, recover more than 87% of energy;

4. HAX series air handling units with heat recovery do not need cooling tower and outside units;

5.  HAX series air handling units with heat recovery is energy saving: in transition season, the fresh air can be used to cool the indoor air, just need to operate the ventilation fan, don't have to start the compressor.

6. Air volume:1500~35000m3/h.

 

High-grade configuration, reliable running

 

Global famous hermetic scroll compressor is used; external balance thermostatic expansion valve, solenoid valve and other refrigerating parts of renowned brands are adopted.

 

Fully fresh air, high air quality

 

Fresh air coming from outside can be directly treated by the unit, and polluted indoor air due to human activities and building materials can be exhausted; fresh air, exhaust air channel heat exchange not only meet air conditioning requirements, but also ensures the absolute fresh air, fundamentally prohibiting cross contamination of air, and ozone disinfection UV germicidal lamp and high static pressure dust removal device are also optional.

 

 Independent fresh air refrigerating system

 

Compared to conventional chilled water systems, the evaporative temperature of the unit is 8~10℃ higher, and a second heat exchange for the transfer of chilled water is not needed, improving refrigerating efficiency by at least 30%.

 

Total heat recovery technology, with heat recovery efficiency for at least 85% and evaporative condenser units up to 92%

 

Low-temperature low-humidity indoor exhaust air is used as the cooling air of the evaporative condenser, which not only uses the sensible heat (temperature difference) of the indoor air exhaust heat, but uses the latent heat (humidity difference), ensuring condensation effect is greatly better than that of the direct using outdoor air for cooling, preventing the energy loss due to air displacement and ventilation. Likewise, during heating of the unit, the high or low-temperature air exhausted from indoors can be used as the heat exchange source at the side of the evaporator. Compared with traditional central air conditioning systems, it saves energy for about 50%.

 

 No condensed water drain system (unique for evaporative condenser)

 

The condensed water coming from fresh air evaporation and to be treated can be directly introduced into the air exhaust condensation system of the unit as the cooling water, without the use of a condensed water discharge system. Because lower condensed water temperature, not only the cooling capacity can be recovered, but the advanced film-type water cooling method can be utilized, enabling the cooling water to sufficiently wet the condensing fins, reinforce the heat exchange of condensing plate, and effectively overcome the scale phenomenon due to the water film on the fin liable to “dry point”

 

Advanced control, safe and reliable

 

English LCD interface and microcomputer intelligent controller are adopted, have advanced control and complete functions; mechanical and electrical integrated design achieves unit start/ shutdown program management, timing control, failure warning and fault self-diagnosis and other functions; the controller boasts optimal automatic control and powerful anti-interference capacity; multiple protections for e.g. lack of phase, phase sequence and unbalance, compressor overload, start delay, and abnormal air suction and discharge pressure, and so on, ensuring running safety.

 

This unit is mainly used in places where refrigeration and introduction of fresh air are required at the same time, such as hotels, factory workshops, underground civil air defense projects.
