Diesel engines, especially for trucks and buses, cause many economical and ecological problems. Diesel exhaust emissions are a major source of pollution in most urban centers around the world. Furthermore, the price of crude oil continues to increase rapidly. The use of alternative fuels...

In common air conditioning methods, both sensible and latent loads are handled by cooling systems. Utilizing desiccant, individual cooling and dehumidification processes are possible. In this paper, desiccant wheel operation has been investigated by experimental study. Experimental conditions...

This paper proposes a new method of ice production using a simple insulation lid and a self-contained ice production. Results of experiments in a freezer showed that ice could be produced with three proposed containers. It was possible to produce ice using a flat-plate-type simple insulation lid...

In this study, a beta-type 300-W Stirling engine is developed and tested, and a non-ideal adiabatic model is built and applied to predict performance of the engine. Engine torque, engine speed and shaft power output are measured under various operating conditions. The experiments are conducted...

This paper presents experimental studies on a solar-assisted ground coupled heat pump (SAGCHP) system for space heating. The system was installed at the Hebei Academy of Sciences in Shijiazhuang (lat. N38°03′, long. E114°26′), China. Solar collectors are in series connection with the...

The long-term thermal storage by absorption process studied in this paper is devoted to building heating. A demonstrative prototype that can store 8 kWh of heat and produce a heating power of 1 kW has been designed and built. It has been tested in static and dynamic operating conditions, which...

This paper describes the thermodynamic analyses of a DAR (diffusion absorption refrigeration) cycle. The experimental apparatus is set up to an ammonia–water DAR cycle with helium as the auxiliary inert gas. A thermodynamic model including mass, energy and exergy balance equations are...

In this study, heating and cooling performances of counter-flow Ranque–Hilsch vortex tubes (RHVT) were experimentally investigated and modeled with a RBMTF (Rule-Based Mamdani-Type Fuzzy) modeling technique. Input parameters (ξ, L/D) and output parameters ΔTh, ΔTc were described by RBMTF...
