84 In addition to a maximum connection of 64 indoor units to 1 outdoor unit, large allowances for piping length and level difference provide a flexible layout. c. Flexible Layout 360° airflow improves temperature distribution and offers a comfortable interior environment d. Ceiling Mounted Cassette (Round Flow) Type VRV systems enable individual climate control settings for each zone to provide the utmost in comfort to commercial building settings. e. Individual Control Figure 3: Variable Refrigerant Volume HVAC System As per analysis, luminous efficacy of LED lights are at pardue to low power consumption in driver circuit& negligible loss of power in terms of heat generation. An occupancy sensor is an indoor motion detecting device used to detect the presence of a person to automatically control lights or temperature or ventilation systems. The sensors use infrared, ultrasonic, microwave or other technology. The term encompasses devices as different as PIR sensors, hotel room keycard locks and smart meters. Occupancy sensors are typically used to save energy, provide automatic control, and comply with Installation of LED lights Lights controlled by occupancy sensor building codes. Motion sensors are often used in indoor spaces to control electric lighting. If no motion is detected, it is assumed that the space is empty, and thus does not need to be lit. Turning off the lights in such circumstances can save substantial amounts of energy. In lighting practice occupancy sensors are sometime also called “presence sensors” or “vacancy sensors”.
