Description
Technical field:
The utility model relates to a kind of lithium bromide absorption type heat pump unit, particularly relates to a kind of second lithium bromide absorption type heat pump unit that has condenser water as refrigerant liquid level detection device.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.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 second lithium bromide absorption type heat pump unit that can make the condenser cryogenic fluid pump be in the band condenser liquid level detection device of steady operational status is provided.
The purpose of this utility model is achieved in that a kind of second lithium bromide absorption type heat pump unit with the condenser liquid level detection device, comprise absorber, evaporimeter, generator, condenser, solution heat exchanger, the concentrated solution pump, condenser water as refrigerant liquid capsule, the condenser cryogenic fluid pump, evaporimeter refrigerant cycle pump, and the pipeline of each parts of connection, valve, it is characterized in that: on condenser water as refrigerant liquid capsule, condenser water as refrigerant liquid level detection device is housed, on the condenser cryogenic fluid pump, increase condenser cryogenic fluid pump frequency converter again, control the flow of condenser cryogenic fluid pump jointly according to condenser water as refrigerant liquid level detection device and condenser cryogenic fluid pump frequency converter, make its discharge capacity and the cryogen water yield correspondence of condenser generation, make the condenser cryogenic fluid pump be in steady operational status.Adopt above condenser cryogenic fluid pump control method, can satisfy when the source pump variable parameter operation, cryogenic fluid pump is adjusted the water as refrigerant flow of discharge automatically with the situation of change of source pump operating mode, 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.
The second lithium bromide absorption type heat pump unit of the utility model band condenser liquid level detection device, described condenser water as refrigerant liquid level detection device is connected with condenser water as refrigerant liquid capsule, minimum high liquid level and two liquid level detecting positions of low liquid level of being provided with in this condenser water as refrigerant liquid level detection device.Also can increase the detecting position that middle liquid level is arranged.
Description of drawings:
Fig. 1 is the general structure schematic diagram of the second lithium bromide absorption type heat pump unit of the utility model band condenser liquid level detection device.
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, and unit shown in Figure 1 is 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 connects the second lithium bromide absorption type heat pump unit of the band condenser liquid level detection device that pipeline, valve constituted of each parts.It is by on condenser water as refrigerant liquid capsule 7 condenser water as refrigerant liquid level detection device 10 being housed, increasing the flow that condenser cryogenic fluid pump frequency converter 11 is controlled condenser cryogenic fluid pump 8 again on condenser cryogenic fluid pump 8.Described condenser water as refrigerant liquid level detection device 10 is connected with condenser water as refrigerant liquid capsule 7.Minimum high liquid level and two liquid levels of low liquid level that detect unit permission control on this condenser water as refrigerant liquid capsule 7, the detection of liquid level in the middle of also can increasing.
The control method of condenser cryogenic fluid pump is: unit is when starting operation, when the water as refrigerant liquid level reaches low liquid level, cryogen device cryogenic fluid pump frequency converter 11 starts condenser cryogenic fluid pump 8 by a fixed frequency, detect the liquid level of water as refrigerant by condenser water as refrigerant liquid level detection device 10, when liquid level was between high and low liquid level, cryogen device cryogenic fluid pump frequency converter 11 was by current frequency operation.When water as refrigerant reached high liquid level, the control system by unit made cryogen device cryogenic fluid pump frequency converter 11 increase certain value on current basis, and after high liquid level disappeared, cryogen device cryogenic fluid pump frequency converter 11 frequencies were kept currency.When water as refrigerant reached low liquid level, control system cryogen device cryogenic fluid pump frequency converter 11 frequencies by unit reduced certain value on current basis, and after low liquid level disappearance, cryogen device cryogenic fluid pump frequency converter 11 is kept currency.
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.
