Book excerpt: Heat Pump Centered-Integrated Community Energy Systems (HP-ICES) show the promise of utilizing low-grade thermal energy for low-quality energy requirements such as space heating and cooling. The Heat Pump - Wastewater Heat Recovery (HP-WHR) scheme is one approach to an HP-ICES that proposes to reclaim low-grade thermal energy from a community's wastewater effluent. The concept of an HP-WHR system is developed, the potential performance and economics of such a system is evaluated and the potential for application is examined. A thermodynamic performance analysis of a hypothetical system projects an overall system coefficient of performance (C.O.P.) of from 2.181 to 2.264 for wastewater temperatures varying from 50°F to 80°F. Primary energy source savings from the implementation of this system is projected to be 5.014 QUADS, or the energy equivalent of 687 millions tons of coal, from 1980 to the year 2000. Economic analysis shows the HP-WHR scheme to be cost-competitive, on the basis of a net present value life cycle cost comparison, with conventional residential and light commercial HVAC systems.

Book excerpt: Heat-pump-centered integrated community energy systems are energy systems for communities that provide heating, cooling, and/or other thermal energy services through the use of heat pumps. Since heat pumps primarily transfer energy from existing and otherwise probably unused sources, rather than convert it from electrical or chemical to thermal form, HP-ICES offer a significant potential for energy savings. Results of the System Development Phase of the HP-ICES Project are given. The heat-actuated (gas) heat-pump incorporated into this HP-ICES concept is under current development and demonstration. The concurrent program was redirected in September 1977 toward large-tonnage applications; it is currently focusing on 60- to 400-ton built-up systems for multi-zone applications. This study evaluates the performance of a HAHP-ICES as applied to a community of residential and commercial buildings. To permit a general assessment of the concept in non-site-specific terms, the sensitivity of the system's performance and economics to climate, community size, utility rate structures, and economic assumptions is explored.

Available in PDF, EPUB and Kindle. Book excerpt: A Heat Pump Centered-Integrated Community Energy System (HP-ICES) concept was explored and developed that is based on use of privately owned ice-making heat pumps in each building or complex within a community. These heat pumps will provide all of the space heating, space cooling and domestic hot water needs. All of the community input energy required is provided by electrical power, thereby eliminating a community's dependence on gas or oil supplies. The heat pumps will operate in both air and water source modes, deriving performance advantages of both. The possible forms of an HP-ICES system, the technical and economic limitations, environmental impacts and other factors are discussed from a general viewpoint. The concept is applied to a specific planned community and its performance and economic features are examined in detail. It is concluded that the HP-ICES concept is technically viable, but that its economic desirability as compared with conventional heat pump systems is hampered by much higher initial costs, and that the economic feasibility of HP-ICES systems will depend on future fuel source costs and supply and on electric power rates.

Book excerpt: The concept of a heat pump centered integrated community energy system (HP-ICES) was explored based on a reference community located in the Northeast with a population of 10,000. Engineering and economic analyses were performed for the HP-ICES and for conventional heating/cooling systems. Sensitivity analyses were used to determine variations in results from changes in: community size; community energy density; waste heat utilization; energy cost escalation; maintenance and operating personnel; and central HP-ICES ownership. The effect of each of the critical parameters on the economic viability of HP-ICES is shown. Conditions of equal 20-year life cycle costs for HP-ICES and for conventional systems are given. If little or no waste heat is available from nearby industrial installations, high community energy density rates (corresponding to urban conditions) are required for economic viability of HP-ICES. If large amounts of waste heat are available, even relatively loosely built-up communities look promising provided the system is owned by the municipality. If the system is owned and operated by a shareholder-owned public utility, either the community energy density must be high, or large quantities of waste heat must be available, or electricity and oil costs must escalate rapidly during the life of the system to assure economic competitiveness with conventional systems. All HP-ICES use significantly less resource energy than conventional systems. For the baseline system analyzed, HP-ICES use 26% to 40% less resource energy than conventional systems during the heating season and 19% less energy during the peak cooling period. The annual resource energy saving for the HP-ICES is 22% to 34%. It is estimated that the HP-ICES concept is applicable to an average of 500 new communities to be constructed during the 1985--2000 period. The probable resource energy saving during that time period is 1.25 x 1015 Btu.

Book excerpt: Heat Pump Centered-Integrated Community Energy Systems (HP-ICES) show the promise of utilizing low-grade thermal energy for low-quality energy requirements such as space heating and cooling. The Heat Pump - Wastewater Heat Recovery (HP-WHR) scheme is one approach to an HP-ICES that proposes to reclaim low-grade thermal energy from a community's wastewater effluent. This report develops the concept of an HP-WHR system, evaluates the potential performance and economics of such a system, and examines the potential for application. A thermodynamic performance analysis of a hypothetical system projects an overall system Coefficient of Performance (C.O.P.) of from 2.181 to 2.264 for waste-water temperatures varying from 50°F to 80°F. Primary energy source savings from the nationwide implementation of this system is projected to be 6.0 QUADS-fuel oil, or 8.5 QUADS - natural gas, or 29.7 QUADS - coal for the period 1980 to 2000, depending upon the type and mix of conventional space conditioning systems which could be displaced with the HP-WHR system. Site-specific HP-WHR system designs are presented for two application communities in Georgia. Performance analyses for these systems project annual cycle system C.O.P.'s of 2.049 and 2.519. Economic analysis on the basis of a life cycle cost comparison shows one site-specific system design to be cost competitive in the immediate market with conventional residential and light commercial HVAC systems. The second site-specific system design is shown through a similar economic analysis to be more costly than conventional systems due mainly to the current low energy costs for natural gas. It is anticipated that, as energy costs escalate, this HP-WHR system will also approach the threshold of economic viability.
