Refrigeration systems are one of the main causes for huge emissions. However research on the marginal cost of reducing greenhouse gas emissions in refrigeration systems is still limited. This paper presents how to calculate the marginal cost of reducing greenhouse gas emissions when using absorption chillers instead of vapour compression refrigerators in the conditions in Vietnam. The study is calculated for a vapour compression refrigerator with a capacity of kW refrigerant R410A and an absorption chiller H2O LiBr with a capacity of kW using solar energy. The calculation results of the cycle life cost of the absorption chiller are 44 309 736 VND much higher than the vapour compression refrigerator of 19 878 028 VND. However CO2 emissions from absorption chiller are on average lower than that of vapour compression refrigerator. Since then the calculation of the marginal cost of reducing CO2 as VND kg CO2. Therefore the option of using absorption refrigeration has the potential to contribute to reducing greenhouse gas emissions in the refrigeration system. Keywords vapour compression refrigerator absorption chiller the marginal cost of reducing greenhouse gas emissions. 2022 University of Transport and Communications 461 Tạp chí Khoa học Giao thông vận tải Tập 75 Số 5 06 2022 461-469 Tạp chí Khoa học Giao thông vận tải NGHIÊN CỨU TÍNH TOÁN CHI PHÍ BIÊN GIẢM PHÁT THẢI KHÍ NHÀ KÍNH CỦA HỆ THỐNG MÁY LẠNH Phạm Văn Khá
