PROBLEM TO BE SOLVED: To provide an exhaust heat input type single-double effective absorbing cold water heater for forming a hot water evaporator for dispensing with an expensive water heater, and easily switching cooling and heating. SOLUTION: This exhaust heat input type single-double effective absorbing cold water heater has an exhaust heat high temperature regenerator GH, an exhaust heat low temperature regenerator GR, a low temperature regenerator G, a condenser C, an absorber A, an evaporator E, a solution passage and a refrigerant passage for connecting these apparatuses, and is constituted so as to be capable of switching a cooling mode and a heating mode, and is provided with a pipe 22 having a valve V1 for operating at heating mode time for introducing refrigerant vapor to the E or the A from at least one apparatus in a pressure level apparatus of the E, and a pipe 17 having a valve V2 for operating at heating mode time for introducing a solution to the E from a circulating system of an absorbing solution. A pipe 20 for introducing the refrigerant vapor to the C via the heating side of the G is connected to the GH. A pipe having V3 for connecting a lower part of the E and the A or a pipe connected to the A can be arranged in the E. COPYRIGHT: (C)2004,JPO
