Abstract

The invention discloses a lithium bromide flashing absorption type refrigerating machine which comprises an evaporator (1), an absorber (2), a compressor (3), an evaporator pump (4) and an absorber reflux pump (5). A membrane separation filter (6) is arranged outside the absorber (2), the membrane separation filter is provided with a liquid inlet, a liquid outlet and a water outlet, and the liquid inlet, the liquid outlet and the water outlet are connected with a dilute solution outlet of the absorber (2), a strong solution inlet of the absorber (2) and a water inlet of the evaporator (1) respectively. The lithium bromide flashing absorption type refrigerating machine further comprises a flash evaporator (10), a liquid inlet pipe of the flash evaporator (10) stretches into the position below the liquid level of the evaporator (1), and a gas outlet pipe of the flash evaporator (10) is connected to the position below the liquid level of the absorber (2) through a four-way part (14). One of the two remaining ports of the four-way part (14) is communicated with an interface active agent generator (12), and the other port is communicated with a negative pressure pump (13). According to the lithium bromide flashing absorption type refrigerating machine, daily operation cost is reduced, the cooling water amount is reduced, and electric energy consumed by the pump is lowered.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, in particular to a lithium bromide flash absorption refrigerator. Background technique [0002] At present, direct-fired lithium bromide absorption type hot and cold water units are generally used. The exhaust gas temperature of the direct-fired high-pressure generator is about 170°C in the cooling condition, and 155°C in the heating condition. At the same time, the flue gas contains part of water vapor, and the saturation temperature of water vapor is about 57°C. The sensible heat of this part of flue gas and the latent heat of condensation of water vapor can account for 10% of the calorific value of fuel combustion. At present, direct emission cannot be used , resulting in a large waste of flue gas waste heat, while generating heat pollution emissions. [0003] Lithium bromide absorption chillers have the advantages of not needing to consume a lot of electricity, and are widely used in c...
