Abstract

The invention discloses a lithium bromide bromide refrigerating machine capable of recycling heat energy by utilizing a heat pump, which comprises a high pressure generator, a low pressure generator, an evaporator, an absorber, a condenser, a high temperature heat exchanger, a low temperature heat exchanger, a solution pump, a cryogenic fluid pump, a control system, and pipelines and valves for connecting the components. The invention is characterized in that the absorber and the condenser are designed into a heat pump evaporator; the evaporating pipes of the heat pump evaporator replaces the cooling pipes in the absorber and / or condenser; and the cooling pipes in the absorber and / or condenser are respectively connected in series with a compressor, a heat pump condenser and an expansion valve to form a heat pump set, so that the heat released from the absorber and the condenser in the lithium bromide refrigerating machine can be converted into high-grade heat by the heat pump set to be recycled. The invention has the advantage of high production efficiency and enhances the operation stability and adaptability of the refrigerating machine.

Description

technical field [0001] The invention relates to a lithium bromide absorption refrigerator. The cooling pipe in the absorber and / or the condensing pipe in the condenser, a compressor, a heat pump condenser and an expansion valve constitute a heat pump, and the low-temperature heat generated by the lithium bromide refrigerator is transferred through the heat pump. use. Background technique [0002] On the one hand, lithium bromide absorption refrigerators are widely used in the refrigeration industry. During the refrigeration process, lithium bromide absorption refrigerators generate a large amount of low-temperature waste heat. These low-temperature waste heat are not well utilized, resulting in serious waste of energy. [0003] On the other hand, water source heat pump units are mainly used in places where wastewater sources (such as industrial wastewater, production circulating water, bathing wastewater, and urban wastewater) are sufficient, the water temperature is relativ...
