  • Disadvantages Of Variable Speed Motors

    Variable Speed Motors | Air Conditioning Repair Dallas When you hear the term “variable speed”, it is in reference to the fan motor inside the indoor air handler. This component moves the heated or air conditioned air though the ductwork in your home. Garland Heating and Air Conditioning offersHVAC systems with variable speed motors for installation. In addition, it is possible that your existing system is compatible with the motor. Contact us for further information, or ask your HVAC technician if your system is compatible. A convenient time is when you are scheduling your fall maintenance or air conditioning repair in Dallas. Unlike conventional single-speed motors, a variable speed motor is capable of operating at a broad range of speeds precisely controlling the delivery of conditioned air throughout the home. Precise air control delivers the required amount of air when it is needed, and offers a number of benefits: The Benefits of a Variable Speed Furnace • Improved Air Quality: Variable-speed motors with humidistats control humidity levels in the home. The ideal relative humidity is between 30 and 50 percent, for optimal comfort. The consistent airflow provides improved air filtration and improved air quality. • Energy Efficiency: Variable-speed motors consume less energy than conventional motors. For example, the variable speed motor uses approximately one-eighth the amount of electricity used for a conventional single-speed fan motor when it operates at half speed.…

  • Heat Stress: A Case Study

    Introduction Bernabucci et al., 2009 described a reduction in feed intake by finishing lambs as a result of heat stress conditions. Dávila-Ramírez et al., 2014 hypothesized that the use of β-adrenergic agonists as a feeding management strategy to improve carcass characteristics in reduced feed intake lambs. Zilpaterol hydrochloride (ZH) use in steers resulted in the mobilization of tissue from visceral organs and directed these nutrients to carcass tissues during periods of ZH supplementation…

  • Heat And Mass Transfer Properties Of Cooling Tower

    Since is unknown at the bottom of the tower (at H=0), an initial guess for at the bottom of the tower is used. An iterative procedure is performed until the difference between the calculated value and the value obtained by experiments for inlet water flow rate is within the defined tolerance. The solution procedure is shown in fig 5. Figure 5- flowchart of the solution procedure Exergy calculations Specific exergy in cooling tower process, like other psychrometric processes, comprises two…
