Technical field:
The utility model relates to a kind of second lithium bromide absorption type heat pump unit.Be specifically related to the air cooled second lithium bromide absorption type heat pump unit of a kind of employing.Belong to technical field of refrigeration equipment.
Background technology:
The second lithium bromide absorption type heat pump unit in the past as shown in Figure 1.Unit shown in Figure 1 is the second lithium bromide absorption type heat pump unit of standard, and second lithium bromide absorption type heat pump as driving heat source, obtains the thermal source of higher temperature with waste thermal energy under the condition of using cooling, is a kind of equipment of the energy effectively reclaiming waste heat energy.This equipment mainly contains generator 4, condenser 5, evaporimeter 1, absorber 2, solution heat exchanger 3 compositions, and heating flow process is that the waste heat source adds the lithium-bromide solution in the heater, makes it produce water vapour concentration rising simultaneously.The water vapour that the produces water condensation that is cooled in condenser becomes water as refrigerant, cooling water is taken the heat of refrigerant vapour outside the machine out of from condenser, water as refrigerant enters evaporimeter water as refrigerant liquid capsule by condenser cryogenic fluid pump 7, squeeze into the heat-transfer pipe of evaporator surface by evaporimeter refrigerant cycle pump 6 again, draw the heat in waste heat source and evaporate, the concentrated solution in the generator enters absorber by concentrated solution pump 8 through solution heat exchanger and absorbs the refrigerant vapour that evaporimeter is come.Fluid in the heat heating absorber tube that absorption process produces raises the tube fluid temperature, for using with thermal field.
Two class heat pumps when operation the condenser cooling water heat of taking unit out of account for and always add more than 52% of heat, heat is bigger, need expend a large amount of cooling waters, cooling water generally adopts the cooling tower cooling, need cooling water pump and cooling tower and pipe-line system, if cooling water system is distant apart from main frame, and output investment ratio is bigger.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can save the investment of cooling water system, the air cooled second lithium bromide absorption type heat pump unit of employing of saving great lot of water resources.
The purpose of this utility model can be realized by following two kinds of schemes:
Scheme one: the air cooled second lithium bromide absorption type heat pump unit of a kind of employing, this unit comprises evaporimeter, absorber, generator, condenser, solution heat exchanger, control system and connect the pipeline of each parts, pump, valve, it is characterized in that: described condenser adopts air-cooled condenser, it comprises the condenser cylindrical shell, the condenser heat-exchanging tube bundle, blower fan, refrigerant vapour inlet pipe and condenser water as refrigerant liquid capsule, the condenser heat-exchanging tube bundle is arranged at outside the condenser cylindrical shell, be connected with the condenser cylindrical shell by the refrigerant vapour inlet pipe and communicate, condenser water as refrigerant liquid capsule places condenser cylindrical shell bottom, and blower fan places condenser heat-exchanging tube bundle side.The refrigerant vapour that generator comes out enters in the air-cooled condenser heat exchanger tube, and the blower fan of running makes outside the horizontal pipe of plunderring the condenser heat-exchanging tube bundle of air.Make refrigerant vapour condense into water as refrigerant, enter evaporimeter.Adopt air-cooled condenser to replace former water-cooled condenser, do not use cooling water, saved the investment of cooling water system, and save great amount of water resources, for the environment of lack of water, very big advantage and using value are arranged especially.
Scheme two: on the basis of scheme one, above the air-cooled condenser heat exchanger tube of air-cooled condenser, a spray water system is set, when the air cooling second lithium bromide absorption type heat pump unit moves throughout the year, because of environment temperature too high, influence the condensation effect of condenser, by spray water system to air-cooled condenser heat-exchanging tube bundle shower water, improve condensation effect, when environment temperature is low, air cooling separately just can satisfy the condensation requirement, and spray water system is in closed condition, has improved the air cooling second lithium bromide absorption type heat pump unit adaptability of environment to external world, reduce the volume of air-cooled condenser, reduce initial cost.
Description of drawings:
Fig. 1 is the second lithium bromide absorption type heat pump unit schematic diagram in the past.
Fig. 2 is the air cooled second lithium bromide absorption type heat pump unit scheme, one structural representation for the utility model adopts.
Fig. 3 is the air cooled second lithium bromide absorption type heat pump unit scheme, two structural representations for the utility model adopts.
The specific embodiment:
Scheme one: unit as shown in Figure 2, this unit are by evaporimeter 1, absorber 2, generator 4, air-cooled condenser 5, solution heat exchanger 3, evaporimeter refrigerant cycle pump 6, condenser cryogenic fluid pump 7, concentrated solution pump 8, control system (not shown) and connect the air cooled second lithium bromide absorption type heat pump unit of the employing that pipeline, valve constituted of each parts.Air-cooled condenser 5 is made up of condenser cylindrical shell 13, condenser heat-exchanging tube bundle 9, blower fan 10, refrigerant vapour inlet pipe 12 and condenser water as refrigerant liquid capsule 11 etc.Condenser heat-exchanging tube bundle 9 is arranged at outside the condenser cylindrical shell 13, is connected with condenser cylindrical shell 13 by refrigerant vapour inlet pipe 12 to communicate, and condenser water as refrigerant liquid capsule 11 places condenser cylindrical shell 13 bottoms, and blower fan 10 places condenser heat-exchanging tube bundle 9 sides.The condenser heat-exchanging tube bundle can be finned cast, also can be other cast.During the second lithium bromide absorption type heat pump unit operation, the generator bromize lithium dilute solution is by the heating of the waste heat source in managing, bromize lithium dilute solution is condensed to concentrated solution, produce refrigerant vapour, refrigerant vapour enters in the pipe of condenser heat-exchanging tube bundle 9 by refrigerant vapour inlet pipe 12, the blower fan 10 of running makes outside the horizontal pipe of plunderring condenser heat-exchanging tube bundle 9 of air, with the refrigerant vapour heat exchange in the pipe, make refrigerant vapour be condensed into water as refrigerant and get back in the condenser liquid capsule 11, the device cryogenic fluid pump 7 that is condensed is transported in the evaporimeter 1.
