Accelerated Thermal Cycling test for Heat Exchangers Used in Reversible Heat Pump
With increasing efficiency standards and higher energy costs, the demand for reversible air-conditioning/heat pump systems is increasing throughout the stationary market. The heat exchangers in such reversible systems must perform reliably as both evaporator and condenser. The outdoor coil, specifically, is subject to very large changes in both operational pressures and temperatures. With this ...
متن کاملThermal Performance of Borehole Heat Exchangers
An important issue in the design of systems using borehole heat exchangers is to find costeffective methods to construct the borehole heat exchanger so that heat can be injected or extracted from the ground without excessive temperature differences between the heat carrier fluid and the surrounding ground. This paper presents an overview of experiences and current activities in this field.
متن کاملStructural Behaviour of Concrete Energy Piles in Thermal Loadings
The thermo-mechanical behaviour of concrete energy pile foundations with different single and double U-tube shapes incorporated was analysed using the Comsol Multi-physics package. For the analysis, a 3D numerical model in real scale of the concrete pile and surrounding soil was simulated regarding actual operation of ground heat exchangers (GHE) and the surrounding ambient temperature. Based o...
متن کاملThermal behaviour of stirred yoghurt during cooling in plate heat exchangers
In this study, CFD calculations were made in order to analyse the thermal behaviour of yoghurt in a plate heat exchanger, the yoghurt viscosity being described by a Herschel–Bulkley model. The influence of Reynolds number on local Nusselt numbers was analysed as well as the influence of entry effects on average Nusselt number. Numerical runs considering and discarding the influence of temperatu...
متن کاملPerformance of heat exchangers used in whole body perfusion circuits.
The performance of some commonly used heat exchangers has been investigated with particular reference to the effect of varying the water flow. The results demonstrate that there is considerable variation in the performance of most units when the water flow is changed. It is suggested that more information should be provided by the manufacturers of heat exchangers and that there should be a supp...
