Gas Engine Heat Pump System and Component Efficiency and Reliability Improvement. Phase 1 Report June 1985-January 1987

摘要

The Gas Research Institute is directing several research projects to develop gas fired heat pumps for residential and light commercial use. The project work discussed in the report identifies and evaluates potential improvements in the cycle and key components of these heat pumps and provides short- and long-term inputs for the heat pump product development efforts. Principal results of Phase I studies under the project are: test procedures for gas fired heat pumps (GFHP), a cycle analysis model for GFHPs, an assessment of appropriate compressor technology for GFHPs, specification of fan operating strategies, a review of emission standards for GFHPs, identification of low-temperature capacity enhancement issues, a guide on the sizing of field tests, current assessments of foreign technology valuable to GFHPs, and an assessment of the health and safety attributes of methylene chloride.
