November 2009 Meeting
Topic
Energy Efficient Heating of Sanitary Hot Water
Heat pumps can harvest the abundant energy provided by the sun to produce the most energy efficient water heating available. Heat pumps utilize the vapor compression cycle to transfer energy from a low quality heat source to a high quality hot water supply. Heat pump water heaters have zero emissions and further reduce your carbon footprint by maximizing efficiency and minimizing electricity consumed.
The heat pump gathers heat from the surrounding air or water, and deposits the heat into water at a useable temperature. This principle of moving heat with a heat pump, rather than generating it by burning fossil fuel (i.e. natural gas), or electric resistance, makes water heating with heat pumps the best choice for conserving energy. Depending on the temperature of the air or water supplied to the heat pump, water can be heated using as little as one tenth the energy required by electric resistance, or gas.
Heat Pump Water Heating Technology provides commercial and industrial hot water fully compliant for sanitary hot water systems… with no requirement for additional boilers. The need to burn fossil fuels (oil/gas/solid fuel) with associated costs and emissions is eliminated. The dual energy concentrations - sanitary water heating and simultaneous air conditioning - of the heat pump water heater act to put normally wasted energy to work for you heating sanitary water to instant full discharge temperature. Highest energy savings are achieved in the process with proven long durability and trouble-free reliability.
Speaker
Bruce I. Nelson, President of Colmac Coil Manufacturing, Colville, WA
A registered Professional Engineer (P.E.) in the state of Washington, he has been active in ASHRAE at both the local and national levels. Nelson received an Engineering degree in 1980, graduating Cum Laude from Washington State University.
Nelson joined Colmac Coil Manufacturing in 1981. As R&D Engineer he developed the company’s first computerized heat exchanger selection program and accurate computerized heat exchanger cost estimation/quote software. In addition, he created industrial air cooler and air-cooled condenser product lines for Freon and glycol. He also developed the world’s first commercial heat pump product line using R134a refrigerant and introduced stainless steel tube/aluminum fin heat exchangers for industrial ammonia refrigeration systems.
Nelson is a member of ASHRAE/American Society of Heating, Refrigerating, and Air Conditioning Engineers, IIAR/International Institute of Ammonia Refrigeration, IIAR Research Committee, ASHRAE Technical Committee TC1.3 “Heat Transfer and Fluid Flow”, President of Inland Empire Chapter ASHRAE 1993-1994, and was named “Engineer of the Year” for the local Inland Empire ASHRAE Chapter.
