DUPLEX 500-1000 Multi recuperator for commercial use
A great new generation of adaptable compact HVAC units. These units can be 100% customized to various project requirements using professional S7 heat exchangers with regenerative efficiency up to 93%. DUPLEX Multi units can be additionally equipped with integrated or external accessories - water or electric heating, water or direct cooling, shut-off dampers, bypass, recirculation, etc. The units can be installed in various positions, including ceiling mounting, thus meeting all project requirements.
Restaurants
The standard air flow is 50 m3/h per person, an additional 10 m3/h if the person smokes; employees are also included (100 m3/h in smoking rooms). If the building frame surfaces are glass, warm air is usually blown into them in winter to prevent the feeling of cold (customer comfort), and in summer the excess heat is removed by cooling the glass. Part of the air flow is supplied to the space above the bar to ensure a supply of fresh air to employees.
Fitness clubs
HVAC systems ensure ventilation of sports facilities (supply of ventilated air to those exercising), removal of moisture and odors, prevent the formation of mold, and can ensure the supply of hot air to compensate for heat losses in the room.
Bore
The standard air flow is 50 m3/h per person, an additional 10 m3/h if the person smokes; employees are also included (70 m3/h in non-smoking rooms, 100 m3/h if smoking is allowed). If the building frame surfaces are glass, warm air is usually blown into them in winter to prevent the cold from being felt (customer comfort), and in summer the excess heat is removed by cooling the glass. Installing HVAC systems with heat recovery in such rooms can significantly reduce costs.
Offices
Apartment buildings
Equal pressure ventilation, the flow of ventilated air depends on the number of people; the economical ventilation mode is 25–30 m3/h per person, at night it can be reduced to 20 m3/h per person. Air heating is carried out centrally in the HVAC unit, each apartment has decentralized heating for comfort; cooling can also be installed. The control system connects individual apartments into a jointly controlled HVAC system. When an HVAC system with heat recovery is used to ventilate apartments, costs can be significantly reduced.
Konferencijų salės
Ventilation when people are seated, 30–60 m3/h per person or according to special requirements. When designing and selecting the HVAC unit, it is necessary to take into account the acoustic requirements of the room. Size: depending on the number of people or heat load. If noise parameters need to be met, a more powerful unit can be used, operating in a weaker mode. The air distribution pattern is different in each case. In large halls, the air supply is installed directly under the chairs.
Swimming pools
The size is usually determined by the amount of moisture (depending on the surface area of the water and evaporation), not the number of people. The air for ventilation is directed to the windows, removing condensation from them. The HVAC system not only provides ventilation, but also compensates for part of the heat loss of the pool area. Pool ventilation can be combined with ventilation of showers at the entrance to the pool. When an HVAC system with heat recovery is used for pool ventilation, costs can be significantly reduced.
Health Center
The amount of ventilated/recirculated air is designed based on the water surface area (evaporating water), the number of showers or people (60–70 m3/h per person). The higher room temperature and heating by the HVAC system must be taken into account. Due to the higher room temperature and higher relative humidity (up to 0 °C, 60% SD), we recommend directing the ventilation air to glass surfaces, thus removing moisture condensation and extracting warm air close to the ceiling.
Squash courts
The amount of ventilated/recirculated air depends on the ventilated area (N x room volume)/space heat loss.
