AC Variable Speed Drives For HVAC Applications

The IMO Jaguar VXH range can make a significant reduction in global energy usage Up to 50% of energy consumption in schools, hospitals, shopping centres, hotels and office buildings is related to air conditioning. The IMO Jaguar VXH series is a dedicated inverter for HVAC applications that offers functions and features designed to create the optimal environment for the people using the building whilst keeping the energy consumption in AHUs, water pumps, compressors, condensers, and others to a minimum. Equally at home as part of a BMS system or as a standalone solution the IMO Jaguar VXH range...

Optimum Control for HVAC Applications Air Handling Unit (AHU) Supply fan / Return fan The speed of supply and return fans can be adjusted to optimise performance according to pressure, discharge temperatures, room temperature, or other environmental conditions. The highest level of energy efficiency can be achieved by controlling the air flow based on the carbon dioxide level in the room. Chilled water pump The chilled water pump circulates the chilled water generated by the freezing machine to the air conditioner and fan coil. The pump speed is adjusted to optimum performance according to the...

Specific HVAC Functions Linearization function This function estimates the target pressure using the flow rate, which allows the estimated terminal pressure to be controlled. For an air-conditioning heat source system, the quantity of the cooling or heating water required fluctuates due to outside temperature or day/night requirements. Therefore, maintaining a constant water pressure may lead to unnecessarily high pressures on terminals at a low operating state and wasted energy at the pump. By controlling the pump, using a correlation of required pressure and the estimated terminal pressure,...

Wet-bulb temperature estimation control This function is used for controlling cooling tower and fans. The wet-bulb temperature could be higher than the set temperature if the external air temperature is too high. In this case the water temperature would not be able to reach the set temperature so the fan keeps rotating at high speed and fails to deliver energy savings. Jaguar-VXH automatically estimates the wet-bulb temperature and controls the fan so that the cooling water is interlocked with the air temperature so as not to Filter clogging prevention function This function detects clogging...
