Heat balance of horizontal ground heat exchangers
This work refers to the modelling of heat transfer in horizontal ground heat exchangers. For different conditions of collecting heat from the ground and different boundary condition profiles of temperature in the ground were found, and temporal variations of heat flux transferred between the ground surface and its interior were determined. It was taken

Study of Ground Heat Exchangers in the Form of Parallel Horizontal Pipes Embedded in the Ground
In order to predict long-term changes in the temperature of the ground in which a horizontal ground heat exchanger has been installed, it is beneficial to implement simplified mathematical models of heat transfer.

Heat transfer characteristics of in-ground heat exchangers
Most in-ground heat storage installations use a system of horizontal or vertical plastic pipes to carry heat exchanger fluid. In designing these systems it is generally assumed that the thermal effects of the plastic pipe can be neglected. This paper reports a laboratory study of the pattern of heat flow around fluid-carrying plastic pipe buried in ...

R32 Partial Condensation Inside A Brazed Plate Heat Exchanger [PDF]
It is well known that when a superheated gas reaches a cold surface, the condensation starts immediately only if the wall temperature is lower than the dew temperature of the refrigerant; in this case, the heat transfer phenomenon can be also affected by

Fouling of a double pipe heat exchanger [PDF]
Every single heat exchanger in operation in modern industries is exposed to fouling to a greater or lesser extent depending on the surface temperature, surface condition, material of construction, fluid velocity, flow geometry and fluid composition.

A derivative method for minimising total cost in heat exchanger networks through optimal area allocation [PDF]
This paper presents a novel Cost Derivative Method (CDM) for finding the optimal area allocation for a defined Heat Exchanger Network (HEN) structure and stream data, without any stream splits to achieve minimum total cost. Using the Pinch Design Method (
