The solution to rise of room temperature caused by water chiller

During operation, water chiller will take some heat away through exhaust outlet. But when indoor space is small, room temperature will rise. Is there any solution to this problem?
Mr. Luo from a university of Singapore that S&A met last week encountered this problem. S&A recommended that Mr. Luo may install a ventilating duct extending to the outside (the diameter of the duct shall be larger than that of exhaust outlet of the water chiller) at the exhaust outlet of the water chiller. This can effectively solve the problem of room temperature rise caused by water chiller.
Mr. Luo would like to use an S&A Water Chiller to cool the 5KW fiber laser independently researched & developed by Mr. Luo. On the official website of S&A, Mr. Luo viewed the types of water chiller and thought CW-7800 water chiller suitable. S&A CW-7800ET dual-temperature dual-pump water chiller with 19KW cooling capacity has two independent temperature control systems, including high-temperature end and low-temperature end. The low-temperature end mainly cools fiber body, and high-temperature end cools QBH connector or lens.
