The refrigerating capacity of the second evaporator 7 about only has 0.84 times of the refrigerating capacity of the first evaporator 6.That is using the superposition type of this patent
, it is necessary to consume high temperature driven heat energy, the overall refrigerating effect freezed using suction-type lithium bromide single-action refrigeration principle after single-action unit
About there was only 1.84 times of the water at low temperature refrigerating capacity of the first evaporator 6, it will again be assumed that the COP of suction-type lithium bromide single-action refrigeration unit is
0.8, then the COP of this patent superposition type single-action unit can reach about 0.8 ÷ 1.84=0.435, with existing superposition type unit
0.364 compares, and improves about 19.4%.
