Description
Technical field:
The utility model relates to a kind of lithium bromide absorption type heat pump unit, particularly relates to a kind of with the self-regulating second lithium bromide absorption type heat pump unit of water as refrigerant flow.Belong to the heating equipment technical field.
Background technology:
The second lithium bromide absorption type heat pump unit in the past as shown in Figure 2.Unit shown in Figure 2 is the second lithium bromide absorption type heat pump unit of standard.Second lithium bromide absorption type heat pump obtains the thermal source of higher temperature with waste thermal energy effect driving heat source under the condition of using cooling water, be a kind of equipment of the energy effectively reclaiming waste heat energy.This equipment mainly is made up of absorber 1, evaporimeter 2, solution heat exchanger 3, concentrated solution pump 4, generator 5, condenser 6, condenser water as refrigerant liquid capsule 7, condenser cryogenic fluid pump 8, evaporimeter refrigerant cycle pump 9.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 the condenser cryogenic fluid pump, squeeze into the heat-transfer pipe of evaporator surface by evaporimeter refrigerant cycle pump again, draw the heat in waste heat source and evaporate, the concentrated solution in the generator enters absorber by the concentrated solution pump 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.
The condenser water as refrigerant enters evaporimeter water as refrigerant liquid capsule by the condenser cryogenic fluid pump, because the load that heats of the cryogen water yield that condenser produces and the second lithium bromide absorption type heat pump unit is directly proportional, so in source pump between 0～100% during variable parameter operation, the cryogen water yield that condenser produces changes 0～100%, the cryogen water yield that the condenser cryogenic fluid pump is discharged such as constant, pump will be inhaled the empty life-span that influences for a long time.Therefore, how to solve the empty problem of suction of condenser cryogenic fluid pump, can not cause the frequent start-stop of pump again, shorten the life-span of condenser cryogenic fluid pump, reduce the reliability of unit, become the difficult problem of the second lithium bromide absorption type heat pump unit.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of self-regulating second lithium bromide absorption type heat pump unit of usefulness water as refrigerant flow that can make the condenser cryogenic fluid pump be in steady operational status is provided.
The purpose of this utility model is achieved in that a kind of with the self-regulating second lithium bromide absorption type heat pump unit of water as refrigerant flow, comprise absorber, evaporimeter, generator, condenser, solution heat exchanger, concentrated solution pump, condenser cryogenic fluid pump, evaporimeter refrigerant cycle pump, reach the pipeline, the valve that connect each parts, it is characterized in that: on condenser cryogenic fluid pump export pipeline, increase by a water as refrigerant bypass and advance condenser tube, advance the automatic regulating valve door that is provided with on the condenser tube by the control of condenser water as refrigerant liquid level in the water as refrigerant bypass again.
The automatic regulating valve door is regulated the cryogen water yield that bypass enters condenser automatically according to the liquid level of condenser water as refrigerant liquid capsule makes condenser cryogenic fluid pump delivery flow enter the amount of evaporimeter and the cryogen water yield correspondence that condenser produces, guarantee that condenser water as refrigerant liquid capsule is in the certain liquid level scope all the time, make the condenser cryogenic fluid pump be in steady operational status, adopt above method, can satisfy when the source pump variable parameter operation, condenser water as refrigerant liquid level is in certain limit all the time, thoroughly solve the difficult problem of controls such as start and stop of unit variable parameter operation condenser cryogenic fluid pump and suction sky, improved the reliability of unit and the stability of operation.
Description of drawings:
Fig. 1 is the general structure schematic diagram of the utility model with the self-regulating second lithium bromide absorption type heat pump unit of water as refrigerant flow.
Fig. 2 is the general structure schematic diagram of the second lithium bromide absorption type heat pump unit in the past.
The specific embodiment:
The utility model is unit as shown in Figure 1, unit shown in Figure 1 be by absorber 1, evaporimeter 2, generator 5, condenser 6, solution heat exchanger 3, concentrated solution pump 4, condenser water as refrigerant liquid capsule 7, condenser cryogenic fluid pump 8, evaporimeter refrigerant cycle pump 9, control device (not shown) and connect each parts pipeline, valve constituted with the self-regulating second lithium bromide absorption type heat pump unit of water as refrigerant flow.It is to increase by a water as refrigerant bypass to advance condenser tube 10 on condenser cryogenic fluid pump 8 export pipelines, advance the automatic regulating valve door 11 that is provided with on the condenser tube 10 by the control of condenser water as refrigerant liquid level in the water as refrigerant bypass again, automatic regulating valve door 11 can be a float-ball type, also can be other pattern.Condenser cryogenic fluid pump 8 discharge pipes are divided into two the tunnel, one the tunnel enters evaporimeter, the water as refrigerant bypass of leading up to is advanced the automatic regulating valve door 11 of condenser tube 10 and the control of condenser water as refrigerant liquid level and is got back in the condenser water as refrigerant liquid capsule 7, operation principle by the automatic regulating valve door 11 of condenser water as refrigerant liquid level control is: when the liquid level of condenser water as refrigerant liquid capsule 7 is lower than certain liquid level, valve wide open, the water as refrigerant bypass is got back to the amount maximum of condenser, enters the cryogen water yield minimum of evaporimeter; Along with liquid level raises, valve is slowly closed, and the amount that bypass is got back to the condenser water as refrigerant reduces, and the cryogen water yield that enters evaporimeter strengthens; When reaching a certain height liquid level, the valve complete shut-down is closed the amount that the water as refrigerant bypass is returned the cryogen device, enters the cryogen water yield maximum of evaporimeter.Advance the bypass amount of being controlled water as refrigerant by the automatic regulating valve door 11 of condenser water as refrigerant liquid level control according to the liquid level of condenser water as refrigerant liquid capsule 7 is set on the condenser tube 10 by the water as refrigerant bypass, make condenser cryogenic fluid pump delivery flow enter the amount of evaporimeter and the cryogen water yield correspondence that condenser produces, guarantee that condenser water as refrigerant liquid capsule 7 is in the certain liquid level scope all the time, makes condenser cryogenic fluid pump 8 be in steady operational status.
Such scheme is applicable to remaining hot water flow process in parallel, serial flow.Generation condenser, evaporation absorber can be that single segment structure also can be a multi-segment structure.The entire arrangement mode, condenser takes place also can be in the above, and evaporation absorber is at the second lithium bromide absorption type heat pump unit of bottom.
