This unit is that a kind of compression combines cold-storage refrigerating integrated unit in the process of absorption refrigeration work with absorption Dual-energy source, its absorption cold-storage flow process such as Fig. 5 shows, heat source system startup, cold water and cooling water system start, cooling water triple valve 2 10 flows vertically to, and flows on the left of cooling water triple valve 4 29.Absorption refrigeration part starts, the absorbent pump 11 of absorption refrigeration parts starts, triple valve 3 14 forward to horizontal flow to, absorbent flows to by absorbent pump 11 after fluid reservoir 15 after heat-exchangers of the plate type 13 on the left of three-way solenoid valve 1, rare absorbent spray-absorption formula generator tray 21 is inherent, be evenly distributed on absorption generator heating surface bank 2 afterwards, additional driving heat source in absorption generator heating surface bank 2, as the thermal source such as used heat or solar energy, rare absorbent is because by heat source, so absorbent is separated with cold-producing medium, and cold-producing medium becomes gaseous state through pervaporation, absorption chiller heating surface bank 28 carries out condensation, because absorption chiller heating surface bank 28 inside is cooling water, so refrigerant vapor is passed through and absorption chiller heating surface bank 28 heat exchange liquefy cold-producing medium, thicken through concentrated absorbent, dense absorbent carries out heat exchange through piping and heat-exchangers of the plate type 13 with rare absorption refrigeration agent, entering afterwards on the absorber tray 24 in absorber 12 is evenly sprayed on absorption heating surface bank 20, dense absorbent enters absorber and is stored in the absorber 12 of absorption refrigeration with in fluid reservoir 15, simultaneously cold-producing medium enter in absorption evaporimeter 16 absorption evaporimeter tray 22 through piping in evenly spray restrain on 19 at absorption evaporator heat transfer, drop in absorption evaporimeter cool-storing box 18 afterwards, complete being separated of cold-producing medium and absorbent, complete absorption process of cool.
Duty six:
Fig. 6 is absorption released cold quantity process schematic.
This unit is that a kind of compression combines cold-storage refrigerating integrated unit in the process of absorption released cold quantity work with absorption Dual-energy source, its absorption released cold quantity flow process such as Fig. 6 shows, cold water and cooling water system start, cooling water triple valve 2 10 horizontal flow to, and cooling water triple valve 4 29 flows vertically to.Absorption refrigeration part starts, the absorbent pump 11 of absorption refrigeration parts starts, triple valve 3 14 forward to horizontal flow to, absorbent flows to by absorbent pump 11 after fluid reservoir 15 after heat-exchangers of the plate type 13 on the left of three-way solenoid valve 1, by inherent for the dense absorbent spray-absorption formula generator tray 21 after concentrated, be evenly distributed on absorption generator heating surface bank 2 afterwards, enter in absorber tray 24 to be evenly sprayed on absorber heating surface bank 20 through heat-exchangers of the plate type 13 afterwards and cool, because absorber heating surface bank 20 inside is cooling water, so concentrated absorbent temperature reduces make ability enhancement, simultaneously because absorption evaporator heat transfer restrains 19 inside for being used for the cold water freezed, cold-producing medium is under certain vacuum degree, absorption evaporator heat transfer is restrained the heat of 19 and evaporates, because this reducing the temperature of refrigeration cold water, thus reach refrigeration object, the cold-producing medium evaporated is not had to drop in absorption evaporimeter cool-storing box 18, again be transported in absorption evaporimeter tray 22 through cryogenic fluid pump 17 and carry out further circularly cooling.Because dense absorbent temperature reduction and cold-producing medium are through heat absorption evaporation, dense absorbent is by the refrigerant suction of evaporation in absorber, and dense absorbent becomes rare absorbent through absorption refrigeration agent, completes released cold quantity and circulates.
