The VRV/VRF system is a multi-split type air conditioner for VRV VRF FINALcommercial buildings that uses variable refrigerant flow control to provide customers with the ability to maintain individual zone control in each room and floor of a building.

System types VRV/VRF systems can be used for cooling only, heat pumping and heat recovery. On heat pump models indoor units can be in either mode but all must be in the same mode if served by the same outdoor unit. The cooling only and heat pump models are basically large, sophisticated, efficient multi-splits. The heat recovery or simultaneous mode systems provide both heating and cooling from the same outdoor unit and thus exploit this technology most effectively. They offer considerable potential for energy savings in many applications. (Read More)

exhaust_ventilationFresh air to enter homes without causing uncomfortable drafts and to prevent indoor pressurization. Kitchens should have separate, manually operated, exhaust fans. The advantages of exhaust ventilation are control and consistency. Moisture, odors, and pollutants are removed continuously, regardless of weather conditions. High indoor air quality is maintained due to the constant infiltration of outdoor air. Exhaust ventilation systems are most suitable for moderate climates. Care must be taken during design and installation to prevent these systems from “back drafting” dangerous combustion gases from fireplaces and gas appliances into homes.

Improved indoor air quality. Exhaust ventilation systems continuously remove moisture, odors, and pollutants. This proactive approach to ventilation can result in improved indoor air quality. Improved comfort. ENERGY STAR labeled homes with tight construction and exhaust ventilation systems can have fewer drafts and a constant supply of outdoor air, resulting in improved comfort. Improved health. Stale air can cause health problems. (Read more)
