HVAC Damper Actuator for Economizer Free Cooling - This damper actuator controls a free cooling damper for an economizer. It is part of an economizer damper system which allows free outside air cooling when the outside air temperature and humidity are ideal. In the Fall and the Spring when the outside air temperatures are mild it is unnecessary to run the air conditioning system to cool the building if the system is set up for free cooling. (more…)
Plate Heat Exchanger and Free Cooling - This plate heat exchanger is used in a data center for a chilled water system and is a chilled water economizer. Heat exchangers are used in marine applications, industrial processes including chemical processing systems, food processing, and many HVAC applications including chilled water applications, hot water applications, and economizer applications.

Free Cooling Air Conditioning - I’m looking for a residential high-performance system that uses an air intake damper or a multistage (multi-zone) heating and a cooling system similar to what I found at Economizer Systems and HVAC Control?
HVAC Tip - A thermocouple is commonly used in standing pilot gas furnaces and water heaters are technically referred to as a copple element and produces millivolts when heat is applied to the tip. This millivoltage is necessary to keep the pilot valve inside the gas valve open. If the pilot flame goes out, the thermocouple stops generating millivolts. Without the millivolts, the valve closes thus preventing gas from escaping when there is no flame. Thermocouples fail because of oxidation. It is recommended that you keep the pilot lit throughout the year to prevent excess oxidation. The thermocouple can be found in many different types of gas furnaces, gas logs, and gas water heaters.
