  • Maximizing Chiller Efficiency | ACHR News

    Nov 24, 2004 · Maximum efficiency occurs with most chillers running at approximately 70-75 percent load and the lowest entering condenser water temperature (ECWT), based on design. Knowing a chiller's efficiency and the effects of load and ECWT will help the facility determine the most efficient chiller configurations, saving the maximum on energy costs.

    Nov 13, 2018 · The numbers for chilled water (44 out 54 in) and condenser water (85 out 95 in) are industry-standard values at full load conditions. Most chillers, regardless of manufacturer, will have a 10°F delta T on the cond and evap. Machines that operate outside of those ranges are chillers that were ordered specifically to provide a lower temp or

    Using this equation and the above design conditions, the temperature change in the evaporator is found to be 10 o F. The water temperature entering the evaporator is then 54 o F.. Most air conditioning design conditions are based on 75 o F and 50% relative humidity (RH) in the occupied space. The dewpoint for air at this condition is 55.08 o F. Most HVAC designs are based on cooling the air to

    Sep 26, 2016 · Since 1 kcal is sufficient energy to raise the temperature of one liter of water 1°C, the impact of this heat release depends on the wastewater strength. For example, a typical domestic wastewater requires only one gram of oxygen for each 10 liters treated, therefore the temperature rise would be only 0.35°C, a negligible amount.

  • Getting into Hot Water: A Practical Guide to Hot-Water

    2 days ago · The rate of heat transfer to the load (for instance, from radiators to the air inside a greenhouse) is greatly reduced as the temperature of the heated incoming water approaches the load air temperature. For that reason it is desirable to maintain the lower water storage temperature at least 35°F above the desired load temperature.

    The life of the water heater is expected to be about 10 years. Use an appropriate cost for electricity and compare the operating expenses. Heat required (BTU) = m x C p x (Temperature Difference) Where C p is the heat capacity of water (1 BTU/lb/F) and m is the mass of the water (Assume 1 gal has 8.3 lb of water and the 3,412 BTU = 1 kWh) Solution

  • How does the temperature of ocean water vary? : Ocean

    This results in less warming of the water. Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
