Available in PDF, EPUB and Kindle. Book excerpt: Energy Utilization Systems, Inc. (EUS), has developed an electric heat pump water heater for residential applications. A heat pump water heater is a device that works like a room air conditioner except that it pumps heat from a room, basement, garage, etc., into an attached water tank instead of rejecting this heat out-of-doors. The development of this device was the first phase of work sponsored by the U.S. Department of Energy through the Oak Ridge National Laboratory under contract number7321.The second phase of work involved the field demonstration of this device. Eighty-five heat pump water heaters were installed in single-family homes located in the service territories of 20 geographically and climatically dispersed electric utilities. The objective of this phase was to demonstrate the reliability and operating efficiency of the device. Utility personnel collected operating data and forwarded it to EUS on a monthly basis. These data were then analyzed and a monthly coefficient of performance(COP) was calculated for each unit. This report details the results obtained from this field demonstration project.

Book Synopsis Pumping Away and Other Really Cool Piping Options for Hydronic Systems by : Dan Holohan
Download or read book Pumping Away and Other Really Cool Piping Options for Hydronic Systems written by Dan Holohan and published by . This book was released on 1994 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: I wrote this book to describe the beautiful workings of hydronic heating systems and I tried to use words that made the subject spring to life in a visual way. It's been one of my best-selling books for years. I kept the drawings simple. Even if you've never worked with hydronics before, you'll be able to follow these drawings. The first part deals with boiler-room piping and explains how you can put the discoveries of the late, great Gil Carlson to work for you. If you pipe Gil's way, you'll save time, money and never again have to bleed radiators. Thousands of installers have reported great success by following the principles in the first part of this book. I wish I could take credit but the genius was Gil Carlson's. I just did my best to tell his story in plain English. The second half of the book takes the "Pumping Away" boiler-room piping design and applies it to a delicious menu of piping options. This is a book that you'll refer to again and again. It will save you time and money. And I guarantee that. - Dan Holohan
Book Synopsis Research and Development of a Heat Pump Water Heater. Volume 1. Final Summary Report by :
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.

Download or read book Research and Development of a Heat-pump Water Heater. Volume 2. R and D Task Reports written by and published by . This book was released on 1978 with total page pages. 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.

Book Synopsis Reliable, Economic, Efficient CO2 Heat Pump Water Heater for North America by : Young Park
Download or read book Reliable, Economic, Efficient CO2 Heat Pump Water Heater for North America written by Young Park and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Adoption of heat pump water heating technology for commercial hot water could save up to 0.4 quads of energy and 5 million metric tons of CO2 production annually in North America, but industry perception is that this technology does not offer adequate performance or reliability and comes at too high of a cost. Development and demonstration of a CO2 heat pump water heater is proposed to reduce these barriers to adoption. Three major themes are addressed: market analysis to understand barriers to adoption, use of advanced reliability models to design optimum qualification test plans, and field testing of two phases of water heater prototypes. Market experts claim that beyond good performance, market adoption requires 'drop and forget' system reliability and a six month payback of first costs. Performance, reliability and cost targets are determined and reliability models are developed to evaluate the minimum testing required to meet reliability targets. Three phase 1 prototypes are designed and installed in the field. Based on results from these trials a product specification is developed and a second phase of five field trial units are built and installed. These eight units accumulate 11 unit-years of service including 15,650 hours and 25,242 cycles of compressor operation. Performance targets can be met. An availability of 60% is achieved and the capability to achieve>90% is demonstrated, but overall reliability is below target, with an average of 3.6 failures/unit-year on the phase 2 demonstration. Most reliability issues are shown to be common to new HVAC products, giving high confidence in mature product reliability, but the need for further work to minimize leaks and ensure reliability of the electronic expansion valve is clear. First cost is projected to be above target, leading to an expectation of 8-24 month payback when substituted for an electric water heater. Despite not meeting all targets, arguments are made that an industry leader could sufficiently develop this technology to impact the water heater market in the near term.
