Abstract
PERFORMANCE OF AN R410A FILLED C-SHAPE HEAT PIPE
Highlights
In a typical air conditioning system, the supply air would be chilled to below the dew point temperature in the refrigeration machine in order to remove moisture and reduce its humidity
He concluded that there was no significant difference between the performance of the R134A- and R410A-filled thermosyphon and that the mean evaporator and condenser heat transfer coefficients were independent of fill ratio and inclination
The results showed that the temperature distribution along the evaporator section was quite uniform at the power inputs applied from 40-100W
Summary
In a typical air conditioning system, the supply air would be chilled to below the dew point temperature in the refrigeration machine in order to remove moisture and reduce its humidity. The heat exchange before and after the cooling coil can be performed by using a heat exchanger In this case, energy needs to be supplied to power the recirculating pump. HPHEs are popular due to the fact that they are efficient and function passively They are used in various applications such as waste heat recovery from hot exhaust flue gas or to replace the wrap around coil in an air conditioning system. It consists of two banks of single or multiple rows of thermosyphons with each set of pipes bent into a C-shape. The slope angle of the CST is defined as the angle θ measured from the horizontal of the plane containing the thermosyphon, Fig. 1
