“…An internal combustion gas engine is used to drive the compressor instead of an electric motor [12]. Many investigators have focused on GEHPs used for air conditioning, operational control, and few of them have considered water cooling or heating applications [13][14][15][16][17][18].…”

“…Another important research subject of GEHP is the evaluation method for the system performance. Up to now the two performance evaluation methods mostly used by many researchers are primary energy ratio (PER) [14,15,17,18] and seasonal primary energy ratio (SPER) [19]. It is possible to use SPER method for the evaluation of the gas engine heat pump systems utilized for water heating.…”

“…It is possible to use SPER method for the evaluation of the gas engine heat pump systems utilized for water heating. However, SPER method is very complex in procedure to use [19]. As a result, Zhang et al [19] presented a new and better evaluation method called integrated primary energy ratio (IPER) based on the PER and SPER methods.…”

An eQUEST model was developed to conduct a study of a natural gas engine driven heat pump (GEHP) for an office building in Woodstock, Ontario. The results were also compared with a roof-top unit to investigate annual potential energy saving using GEHP. The models were also calibrated with regression analysis which was obtained from measured data and validated with respect to ASHRAE Guideline 14-2002. The developed ad validated models were used to predict the performance of these system in different regions of Ontario; Toronto, Ottawa, Windsor and Thunder Bay. The results for five cities were compared in terms of annual energy, GHG and energy cost savings. It was concluded that Thunder Bay has the highest annual energy and GHG saving, while Toronto has the highest annual energy cost saving.

We consider the possibility of improving the existing heat-suppling system in Chelyabinsk through the introduction of heat pump technology for the disposal of waste low-grade heat. Sources of information concerning the ways of utilization of waste thermal energy, the principles of work of heat pumps, classification of city sources of waste heat are analyzed. The technique directed to assess the effectiveness of applying heat pumps for each category of city sources of waste thermal energy is designed. The calculated assessment showed that the utilization of waste heat in the conditions of Chelyabinsk will reduce the annual energy of fuel consumption by 2.2 million tons of conventional fuel (24.9%). At the same time, thermal pollution will decrease by 1.5 million tons of equivalent fuel. This effect is possible with the use of heat pumps with a total heat output of 1,145 MW.
