A high seasonal performance factor gas heat pump for the north central United States Abstract The High Seasonal Performance Factor (HSPF) gas heat pump development and demonstration program is described.
The heating performance of unitary air-source heat pumps is typically represented by the Heating Seasonal Performance Factor (HSPF). The HSPF is a single value that is intended to represent the overall efficiency of the heat pump for the entire heating season, and is the ratio of output capacity in BTU/hr (Btuh) to power input in Size: KB.
The Seasonal Performance Factor (SPF) High Seasonal Performance Factor Gas Heat Pump for the North Central United States book applies to heat pumps. It is a measure of how efficiently your heat pump is operating. Put simply, the higher your SPF value the more energy efficient your system is.
SPF is a measure of the operating performance of an electric heat pump heating. The Seasonal performance Factor (SPF) is the average Coefficient of Performance (CoP) of a heat pump over the full heating season.
The CoP is the ratio of heat output (in kilowatts) over the electrical input (in kilowatts) at any one time. The CoP will fall if the input temperature available to the heat pump falls. SEasonal PErformance factor and MOnitoring for heat pump systems in the building sector SEPEMO-BUILD The project aimed at overcoming market barriers to a wider application of heat pumps, namely the lack of robust data on the conditions "in real installations" inﬂuencing reliability and seasonal eﬃciency, i.e.
the seasonal performance factor. The seasonal performance factor takes into account how well the pump works at both low and high temperatures, and is a far better reflector of how efficient your pump will be than the CoP.
It allows you to make calculations between different ground, air and even water source heat pumps, which is pretty fundamental since the variation in costs between the different units.
field test, monitoring, seasonal performance factor 1 INTRODUCTION Heat pump models can be used during planning processes to predict the performance of heat pumps with electrically driven compressors 1, or in research and development to analyse the component behaviour, for example a heat pump integrated in different system layouts.
The seasonal performance factor (SPF) of a heat pump is the pump's average output of heat over a full heating season. The SPF is the figure which department of energy and climate change (DECC) will use to calculate whether you are eligible for renewable heat incentive (RHI) payments when the domestic scheme High Seasonal Performance Factor Gas Heat Pump for the North Central United States book in spring Default values of Seasonal Performance Factor for heat pumps Reference no.

Heating Seasonal Performance Factor (HSPF) - (Heating) A representation of the total heating output of a central air-conditioning heat pump in Btus during its normal usage period for heating, divided by the total electrical energy input in watt-hours during the same period, as determined using the test procedure specified in the California Code.
The Seasonal Performance Factor (SPF) is a measure of how energy efficient your heat pump is. Read a full explanation and download a calculation template to use in your application for the Domestic Renewable Heat Incentive.
Climatic impacts on heating seasonal performance factor (HSPF) and seasonal energy efficiency ratio (SEER) for air-source heat pumps Article in ASHRAE Transactions January with. Heating seasonal performance factor (HSPF) is a term used in the heating and cooling industry.
HSPF is specifically used to measure the efficiency of air source heat pumps. HSPF is defined as the ratio of heat output (measured in BTUs) over the heating season to electricity used (measured in. Heating Seasonal Performance Factor (HSPF) Heating Seasonal Performance Factor (HSPF) is a heating efficiency rating for heat pumps.
The higher the rating, the more efficient the heat pump. A more efficient heat pump will result in less energy use and increased energy savings over the life of the system, compared to a less efficient heat pump. 2 Factors affcting air source heat pump performance 12 Principles of the heat pump cycle 12 Practical heat pumps 14 Improvements to the basic practical heat pump cycle 16 Defrost cycles 17 Heating systems and seasonal performance factor 19 3 Literature review 24 4 Methodology 28 IDEAS methodology 28File Size: 1MB.

Delivery date: Authors: R. Nordman, P. Rivere. Work Package 2/3File Size: 1MB. By JIS B , which states the evaluation method for the rated performance for package air conditioners, APF (Annual performance factor) is adopted.
Thus, improvements for the real annual performance are needed. As for this APF, we wanted to calculate the CSPF (Cooling seasonal performance factor), COP of low load intermittent driving is. Ground source heat pump systems are ideally matched to modern warm temperature underfloor heating because a heat pump transfers heat at a higher coefficient of performance if it delivers to a large warm water circuit (like underfloor heating) rather than a small high.
The energy simulation results were compared to three baseline cases: % electric resistance heating, a Btu/Wh ( W/W) heating seasonal performance factor (HSPF) single-speed air-source heat pump unit, and 90% AFUE gas heating system.
The heat pump model can be coupled with a building model in order to calculate a seasonal energy efficiency ratio SEER and a seasonal coefficient of performance SCOP. These results are used to choose efficient components and technical options to maximize the Cited by: Dynamic Test Method for the Determination of the Global Seasonal Performance Factor of Heat Pumps Used for Heating, Cooling and Domestic Hot Water Preparation scenario for geothermal heat pumps is the high inertia of the “real” performance data of the heat pump; The approach is illustrated in Figure 5 for the whole testing period.
The gas engine-driven heat pump (GEHP) technology relies on gas engines to generate the mechanical energy required to operate the heat pump. Generating the desired mechanical power for the HP system on site avoids a two-stage penalty, i.e., first the generation losses at the power station and second, the transmission and distribution by: ISO also specifies the seasonal performance test conditions and the corresponding test procedures for determining the seasonal performance factor of equipment, as specified above, under mandatory test conditions and is intended for use only in marking, comparison, and certification ry: p.

Seasonal Performance. Because air source heat pumps move the outside air to heat the internal space of the home, they are dependent on the seasonal fluctuations of the outside temperature. To reflect that dependence, the performance of heat pumps is rated with a Seasonal Performance Factor (SPF).
