Working Principle of HISURP Rooftop Unit

*Cooling mode*

The outdoor finned heat exchanger acts as the condenser, and the indoor finned heat exchanger acts as the evaporator. The high-temperature refrigerant gas discharged from the compressor is condensed into liquid in the outdoor finned heat exchanger. After being throttled and depressurized by the expansion valve, it becomes a low-temperature gas-liquid mixture and flows into the indoor finned heat exchanger. After absorbing heat and evaporating, it returns to the compressor, completing one refrigeration cycle. At the same time, the return air (or fresh air) from the room is cooled down after passing through the indoor finned heat exchanger (which acts as the evaporator). The cooled air is then sent back into the room by the indoor fan.

Advantages of Rooftop Unit

HISURP rooftop units are all-air systems with an integrated design, eliminating the need for water pumps, cooling towers, fan coil units, and condensate drain pipes, making installation and use extremely convenient.

With no moving machinery or water pipes inside the system, users are free from noise and leakage concerns, and maintenance is easy.

The unit is placed on the roof or in open outdoor space, eliminating the need for a machine room and saving on initial investment.

The unit requires no secondary refrigerant, resulting in high system efficiency.

The unit is multifunctional, easily providing air purification, dehumidification, humidification, cooling, heating, and fresh air volume adjustment.

Components of HISURP Rooftop Unit

*DAIKIN or COPELAND scroll compressor*

The highly efficient and energy-saving scroll compressor is located outside the airflow path, allowing maintenance personnel to perform necessary repairs on the refrigeration cycle without shutting down the unit. The compressor is mounted on a rubber vibration-damping base to reduce noise and vibration.

*Indoor Fan & Motor*

The fan adopts a forward-curved multi-blade centrifugal double-suction impeller. The impeller has been dynamically balanced and has no noise or vibration during long-term operation to ensure a high air delivery effect. The belt pulley drive can flexibly change parameters such as unit air volume and external static pressure to match the actual project. The fan comes with a motor adjustment plate, which can easily adjust the belt tension.

*Heater*

Air electric heaters have a wide range of applications: they can heat any gas, and the hot air produced is dry, non-conductive, non-flammable, non-explosive, non-chemically corrosive, pollution-free, safe and reliable, and the heated space heats up quickly.

*Axial Fan*

It has excellent controllability, is extremely durable, and has a precise structure. It is highly efficient, low-noise, reliable, consumes little power, and can be used in high-temperature environments.

*Coil*

The evaporator coil uses high-purity seamless internally threaded copper tubing and aluminum fins for airflow regulation. Mechanical expansion ensures a tight bond between the copper tubing and aluminum fins, maximizing heat transfer efficiency.

The aluminum fins undergo a hydrophilic treatment, effectively reducing the thickness of the condensate film during refrigeration, lowering the water film thermal resistance, and improving the coil's heat transfer efficiency.
