Supply - 2EVOP condensing exhaust heat recovery type fresh air rooftop air conditioner

The series adopts the world's first high-efficiency elliptical tube heat exchanger. The air supply and exhaust are designed into an integrated structure, and the exhaust air heat is recovered while sending in fresh air. It has greatly improved and created a new realm of energy-saving fresh air air conditioners. Copy of condensation exhaust heat recovery type fresh air integrated air conditioner
With the increase in the number of buildings with high sealing performance that cannot open windows, the introduction of efficiently treated fresh air has been paid more attention than ever. The series is specially designed for places with strict energy saving requirements such as: offices, schools, hospitals, hotels, food industry, large commercial places, and airports. Outdoor fresh air treatment includes cooling, reheating, heating, humidification, filtration and other options.
Features of the unit
Characteristics
The high-efficiency elliptical tube heat exchanger uses an elliptical tube heat exchanger to increase the heat exchange efficiency and reduce the pressure on the supply side. While improving the performance of the equipment, the The equipment volume is greatly reduced and can be adapted to more demanding occasions.
High-efficiency heat recovery The condenser is designed in the exhaust channel to recover heat from the exhaust air, which greatly improves the equipment value. Similarly, this design will not cause overheating of the equipment in summer, greatly improving the reliability of the equipment.
Eliminate cross-contamination. Since the evaporator and condenser are completely separated, there is no cross-contamination of bacteria or odor, and it is very clean.
Easy to install. The indoor and outdoor units have an integrated structure. There is no need to connect refrigerant pipes. You only need to connect the air ducts to operate efficiently.
Precise supply air temperature and humidity control Since subcooling and condensation reheat options can be added to the system, precise control of supply air temperature and humidity is possible, greatly improving the quality of fresh air
Low noise design and double-layer The sheet metal structure design series has special structural designs for noise and vibration (for example, a centrifugal fan replaces an axial flow fan as an exhaust fan), and adopts a double-layer sheet metal structure, so even if it is installed indoors, no sound or vibration will be noticed.
Sealed - Smooth and flat inside, no dust, no air leakage
< Dry - No metal channels between double-layer sheets, no cold bridges Quiet - Better sound insulation than fiberglass Sturdy - Double The laminate metal is not easily deformed, and its high efficiency is twice that of glass fiber. The design and engineering are simplified and no complex supporting equipment such as water piping is required, which saves equipment costs and also makes the design simpler.
Year-round ventilation, regardless of season or time period, can carry out energy-saving operation comfortably and reasonably under set air conditions, and can also greatly save operating costs.
Convenient maintenance The condenser, evaporator and refrigeration circuit are designed as an extractable integrated structure, making daily maintenance very convenient.
