Abstract

The invention discloses a second-class absorption heat pump system and a heating method of the second-class absorption heat pump system. The second-class absorption heat pump system comprises an evaporator, an absorber, a generator and a condenser, and further comprises a refrigerant heat exchanger, wherein a liquid refrigerant outlet of the condenser is communicated with a liquid refrigerant inlet of the evaporator through a first pipe, a liquid refrigerant outlet of the evaporator is communicated with a liquid refrigerant inlet of the condenser through a second pipe, the refrigerant heat exchanger comprises a first heat exchange tube and a second heat exchange tube, the first heat exchange tube and the second heat exchange tube can exchange heat with each other, the first heat exchange tube is connected to the first pipe in series, and the second heat exchange tube is connected to the second pipe in series. According to the structural design of the second-class absorption heat pump system, the problems that a second-class absorption heat pump system is low in energy utilization rate and temperature of a high-temperature heat source is low can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of absorption heat pumps, more specifically, to a second-type absorption heat pump system and a heating method thereof. Background technique [0002] The second type of absorption heat pump system refers to the use of a large number of medium-temperature heat sources to generate a small amount of high-temperature useful heat energy. It takes medium-temperature heat source and low-temperature cold source as input, and high-temperature heat source as output. [0003] Such as figure 1 As shown, the second type of absorption heat pump system in the prior art includes an evaporator 01, an absorber 02, a throttling device, a generator 04, and a condenser 03, wherein the refrigerant vapor outlet of the generator 04 is connected to the outlet of the condenser 03 The refrigerant vapor inlet is connected, the liquid refrigerant outlet of the condenser 03 is connected with the liquid refrigerant inlet of the ...
