Lithium bromide absorption type refrigerator health hot water production energy conserving device when cooling

Abstract

An energy saving device of producing the hot water when the refrigerator of lithium bromide absorption refrigerates belongs to the field of direct burning, steam lithium bromide absorption refrigerator. It includes the high temperature generator and the low temperature generator / condenser. The clean hot water heat exchanger in the high temperature generator is connected with the water inlet and outlet out of the high temperature generator. The character is in that the below of hot water exchanger is set with the condensate recovery device which transform the condensate from the exchanger to the low temperature generator / condenser through the conduit and the adjusting valve. So the invention can not only make cold but make the clean hot water. It can be used in the hotel, cabaret, chemical engineering, food and medicine widely.

Description

technical field [0001] The invention relates to the field of direct combustion and steam lithium bromide absorption refrigerators, in particular to an energy-saving device for producing sanitary hot water when the lithium bromide absorption refrigerators are cooling. Background technique [0002] The lithium bromide absorption refrigerator originated in the United States in the 1940s, was successfully developed by Dr. Carrier, and has been promoted and used around the world. In the 1960s, the first lithium bromide unit was successfully trial-produced in Shanghai 704. Due to its unique energy-saving advantages, it was widely used in my country from the early 1980s to the 21st century. With the advancement of science and technology and the investment of scientific research funds, lithium bromide Refrigeration technology is subject to rapid changes and technological improvements. [0003] Although after years of technical improvement, the original lithium bromide absorption ref...

Problems solved by technology

[0003] Although after years of technical improvement, the original lithium bromide absorption refrigerator still has many defects in terms of energy saving, such as: the direct-fired lithium bromide absorption refrigerator in use now produces sanitary hot water during refrigeration, and the natural gas is burned by the burner to directly heat the high temperature The dilute lithium bromide solution outside the heat transfer tube of the generator, the dilute solution is heated and concentrated to generate high-temperature refrigerant steam, and the high-temperature refrigerant steam heats the sanitary hot water to the rated set temperature. After the sanitary hot water absorbs the heat of the refrigerant steam, the refrigerant The steam condenses into steam condensate, which is directly mixed with the concentrated solution, and the concentration and temperature of the solution are reduced

The energy consumption of sanitary hot water production during cooling increases, the efficiency decreases, and the end user directly increases the operating cost, and the cycle repeats, resulting in energy waste
