\textbf{176.} If the coefficient of performance of refrigerator (1) is 1.5 times the coefficient of performance of refrigerator (2), and both have equal time periods, while both refrigerators are running simultaneously, the heat that refrigerator (1) releases to the outside is how many times the heat that refrigerator (2) releases to the outside?
