Abstract
The present study is a review of the literature on heat pipes. The aim is to determine the feasibility of using this type of heat exchanger in air-conditioning (AC) systems. This paper deals with the principle of operation and design of the heat pipe, provides various ways to return condensate, and describes in detail its thermodynamic cycle. Considerable attention is paid to wick structures and working fluids. The restrictions on the heat transfer of heat pipes that affect heat exchanger performance are noted. Design recommendations found in scientific literature and on the websites of manufacturing companies are also described. The diagrams of the heat pipe designs used in central air conditioners and AC systems are given. An example of an installation using heat pipes as a waste air heat exchanger in a central air conditioner is given. Further, the efficiency and thermal power of various methods of heat recovery are compared with the same initial parameters of the flow rate and temperatures of outdoor/exhaust air. A conclusion is reached regarding the advantages of using heat pipes in AC systems for heat recovery. The reason for the rare use of this heat exchanger is also explained. Different methods of heat recovery are compared, and the prospects of using a heat pipe in AC systems are assessed. Recommendations are given on the direction of further research on this topic.
