Condenser 124 and heat exchanger 130 ensure the temperature difference between the leaving water temperature of water and the inflow temperature of secondary water so that primary
The temperature of water outflow absorption heat exchange unit flows into the temperature of absorption heat exchange unit less than secondary water, while also so that generator
The flow velocity of a lateral line 141 in 121 and the secondary lateral line 142 in evaporator 122 increases, and then improves generator 121
With the coefficient of heat transfer of evaporator 122, heat cost is reduced, reduces the volume of absorption installation.
Further, bypass line is provided on generator 121, bypass line passes through with a lateral line 141.It is inhaling
In receipts formula heat pump 120, since a water is only by generator 121, when the absorption heat exchange unit of the present invention is in anti-caking
Brilliant, anti-hypertonia is when guard modes need to shut down, in order to which the absorption heat exchange unit for ensureing the present invention still ensures that have
Certain heat capacity a, it is thus only necessary to water of generator 121 be set into bypass line, bypass line passes through a lateral line
141 so that a water is by bypass line by a lateral line 141 around generator 121 and the secondary water in heat exchanger 130
