Numerical Analysis of dew point Indirect Evaporative Cooler

Dew-point hygrometry system for measurement of evaporative water loss in infants.

Evaporation of water from the skin is an important mechanism in thermal homeostasis. Resistance hygrometry, in which the water vapor pressure gradient above the skin surface is calculated, has been the measurement method of choice in the majority of pediatric investigations. However, resistance hygrometry is influenced by changes in ambient conditions such as relative humidity, surface temperat...

Advanced Analysis of Dew Point Control Unit of Hybrid Refrigeration Systems in Gas Refineries

In this paper, an advanced analysis of a novel hybrid compression-absorption refrigeration system (HCARS) for natural gas dew point control unit in a gas refinery is presented. This unit separates the heavy hydrocarbon molecules in the natural gas, which is traditionally carried out by natural gas cooling in a compression refrigeration cycle (CRS). The power input required for the refrigeration...

Dew point measurement using a sensitive circuit type of dew point sensor

Received: 13 Mar. 2012; Revised 25 Jul. 2012; Accepted 04 Aug. 2012 Received: April 8, 2012; Revised May 4, 2012; Accepted June 6, 2012 Abstract: Aiming at the problem of atmospheric humidity measurement, this paper proposes a method to measure dew point based on sensitive circuit for the first time. We use the quartz crystal in the Colpitts circuit as the humidity sensitive element. Since the ...
