Paper No 979 – An Experimental Study on the Chemisorption Heat Pump for Low Temperature Heat Source – 14th IEA Heat Pump Conference, Chicago, USA
Global interest in carbon neutrality is increasing for a sustainable society in response to the climate crisis. Various studies are being conducted for carbon neutrality, and among them, many studies related to unused energy are being conducted. Many studies focused on the waste heat recovery system regarding the use of unused energy. Recently, interest in a chemisorption heat pump capable of performing a cooling based on lowtemperature thermal energy has increased. This research conducted an experimental study to understand the performance characteristics of a chemisorption heat pump consisting of a condenser, an evaporator, and two reactors based on a low-temperature heat source (40°C). Experiments were conducted for cases where the adsorption/desorption operation time was 20, 30, and 50 minutes, and the average cooling capacity, COP, and SCP were presented for each condition when performing six alternating operations. As adsorption/desorption operation time went up, average cooling capacity, SCP were reduced and COP was increased.
