Available in PDF, EPUB and Kindle. Book excerpt: The heat pump water heater is a device that works much like a window air conditioner except that heat from the home is pumped into a water tank rather than to the outdoors. The objective established for the device is to operate with a Coefficient of Performance (COP) of 3 or, an input of one unit of electric energy would create three units of heat energy in the form of hot water. With such a COP, the device would use only one-third the energy and at one-third the cost of a standard resistance water heater. This Volume 2 contains the final reports of the three major tasks performed in Phase I. In Task 2, a market study identifies the future market and selects an initial target market and channel of distribution, all based on an analysis of the parameters affecting feasibility of the device and the factors that will affect its market acceptance. In the Task 3 report, the results of a design and test program to arrive at final designs of heat pumps for both new water heaters and for retrofitting existing water heaters are presented. In the Task 4 report, a plan for an extensive field demonstration involving use in actual homes is presented. Volume 1 contains a final summary report of the information in Volume 2.

Download or read book Research and Development of a Heat Pump Water Heater. Volume 1. Final Summary Report written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An electric heat pump water heater with an operating efficiency, E/sub R/, of 2.5 in average conditions of 70 to 75°F ambient air and 55 to 60°F supply water has been designed. With losses taken into account, the coefficient of performance (COP) is 2.8 or within 10% of the design objective. Separate heat pump designs are available for new water heaters and for retrofitting of existing ones. For both models, the compressor, evaporator, fan and controls are mounted in a round cabinet set on top of the water heater. The condenser is a dual tube direct immersion type which enters the tank through a special 4-in. hole in the top of new tanks. For retrofit units, the condenser is in the form of a helix and is screwed into the tank through the hole normally used by the lower resistance element. Early estimates for the cost of the device are between $200 to $250 more than for an electric resistance water heater. Using this estimate, the payback for many applications will be between one and two years with some being less than one year. The payback period is dependent on the amount of hot water consumption and the price of electricity. In warm climates, the benefit/cost ratio will be improved by higher efficiency from warmer ambient air and by the value of free air conditioning and dehumidification provided while the unit is operating. In colder climates, the improved efficiency from colder supply water and the higher operating savings from higher kilowatt-hour use because of the colder water tend to offset the effect of the less favorable climate. A field demonstration of one hundred water heater heat pumps is planned in which each of 20 utilities will purchase, install and service five units, and install, service and monitor instrumentation packages supplied by DOE. This project will deterine the annual COP of each unit and its impact on the heating and cooling load of the house.

This book was released on 2012-12-06 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: We must all hang together or surely we will all hang separately. Benjamin Franklin The significant apathy that characterized relationships between indus try and universities and the adversarial nature of relationships between industry and government have both faded rapidly in the 1980s as the realities of global competition have surfaced in the United States. Both industry and government leaders articulate a number of constructs for regaining our competitiveness in world markets. One of the more fre quent strategies prescribed in this new competitiveness era is cooperation. Different individuals or groups may espouse different definitions, inter pretations, or areas of emphasis, but the overall importance of this concept is substantial. Although examples of cooperative research have existed for several decades, the number and variety of relationships have expanded rapidly in the 1980s as corporations, universities, and governments have embraced this strategy. Joint ventures involving two or three firms increased from under 200 per year in the 1970s to over 400 per year by the mid-1980s. Multiple-firm cooperative arrangements are a more recent phenomenon, made possible by the National Cooperative Research Act of 1984. By mid- 1988,81 of these industry-level consortia had formed under the provisions of the 1984 Act. The rapid growth in cooperative research and development (R&D) is primarily a response to the pressures of international competition. As a corporate strategy, cooperative R&D meets short-term needs for assets to implement new approaches for coping with intensifying competition.
