Description

The small-sized lithium bromide absorbing central air conditioner main machine

Technical field

The utility model relates to a kind of lithium bromide absorbing central air main frame, particularly a kind ofly is applicable to that construction area is at 200-500m ²Between family or commercial affairs use the small-sized lithium bromide absorbing central air conditioner main machine.

Background technology

At present, family expenses lithium bromide absorption type cooling and heating central air conditioner main machine is mainly pump one air-cooled structure, and the circulation of its working medium lithium-bromide solution is finished by canned motor pump, and absorption heat and condensation heat are to be taken away by the wind that blower fan is exported.Because influenced by outdoor temperature bigger for wind-warm syndrome, make evaporating temperature height to 9 ℃, the cold water temperature of making reaches 10-11 ℃, and cooling-down effect is not good enough, and human comfort is also relatively poor.Adopt the main frame of pump-air-cooled structure, because running gear is more, and bigger vibrations and noise are arranged when not only moving, and is unfavorable for environmental protection, and, maintenance capacity is also bigger, and simultaneously, blower fan and pump all need power consumption, its operating cost is also higher, and the blower fan volume is bigger, needs certain air to flow and installing space again, makes that also machine volume is bigger.

The utility model content

The utility model is the deficiency that exists in the above-mentioned background technology, provides that a kind of compact conformation, volume are little, shockproof, noiselessness, operating cost is low, maintenance capacity is little, human comfort is high small-sized lithium bromide absorbing central air conditioner main machine.

Its concrete solution is: adopting the combustion heat with combustion gas is that the circulation power of lithium-bromide solution absorbs hot and cold and coagulates the hot structural design of being taken away by cooling water, mainly is made of generator, vapour liquid separator, condenser, evaporimeter, absorber, solution heat exchanger.Wherein, be provided with between generator and the vapour liquid separator and be used for carrying the pipe that rises of bubble hot solution secretly to the vapour liquid separator conveying, be connected with refrigerant vapour bridge tube from refrigerant vapour to condenser that carry between vapour liquid separator and the condenser, and condenser is connected with evaporimeter through flow controller, absorber and evaporimeter are deadened and adjacent setting by a liquid barrier, one loop input of solution heat exchanger is connected with the weak solution carrier pipe of weak solution in the conveying absorber, the output in this loop is connected with generator through the weak solution carrier pipe, and in the solution heat exchanger with the input in another loop of weak solution heat-shift with carry vapour liquid separator in the return duct of concentrated solution is connected, this loop output lowers the temperature afterwards that the concentrated solution carrier pipe of solution is connected with carrying in absorber.Simultaneously, be provided with a flow controller that can cut off pressure between generator and the absorber between vapour liquid separator and absorber.The weak solution carrier pipe that is connected between generator and solution heat exchanger is provided with the liquid level meter that is used to regulate the generator liquid level.

The utility model is a power with the combustion heat of natural gas or town gas, with the lithium bromide water solution is working medium, utilization is subjected to the hot solution principle that rises to form circulation automatically, take away heat in the machine with cooling water, and cooling water is by evaporative cooling, can make 7-10 ℃ of cold water in summer under the duty, heating of absorber and condenser cooling water system closing made 55-60 ℃ of hot water under the duty in the winter time, this not only not power consumption of main frame, for the natural gas resource of China's abundant has been expanded range of application, the present situation that can't bear the heavy load for supply of electric power has alleviated pressure, has played energy balanced action.And the structural design of the no pump-water-cooled of employing makes its no running gear, does not have wearing and tearing, maintenance capacity is less, shockproof, noiselessness in service, uses that to need not fluid infusion, compact conformation, volume little all the life, and quality of fit requires low, manufacture simple, cost is low, simultaneously, human comfort is also higher.

The specific embodiment

Among Fig. 1 to Fig. 5, generator 1 is connected with the vapour liquid separator 3 that is positioned at its top by the pipe 2 that rises, the condenser 8 that is positioned at vapour liquid separator 3-side is communicated with it by refrigerant vapour bridge tube 14, the evaporimeter 10 that is arranged on condenser 8 bottoms is by a liquid barrier and absorber 7 adjacent settings, and the tube connector of 10 in condenser 8 and evaporimeter is provided with flow controller, the input in solution heat exchanger 9-loop is connected with the vapour liquid separator bottom by return duct 4, and output is connected with absorber 7 tops by concentrated solution carrier pipe 6.Another loop input of solution heat exchanger 9 is connected with absorber bottom by weak solution carrier pipe 16, and output is connected with generator 1 bottom by weak solution carrier pipe 12.Simultaneously, liquid level meter 11 is serially connected on this weak solution carrier pipe 12.And flow controller 5 is arranged between vapour liquid separator 3 and the absorber 7.

During refrigeration, as shown in Figure 4, the bromize lithium dilute solution in the generator 1 is produced bubble by heater 13 heating backs.Density reduces, liquid level raises, the hot solution of carrying bubble secretly enters vapour liquid separator 3 by the pipe 2 that rises, isolate concentrated solution behind the refrigerant vapour through return duct 4 to solution heat exchanger 9, with the weak solution heat-shift of carrying through weak solution carrier pipe 16 from absorber 7, temperature reduces after concentrated solution carrier pipe 6 inflow absorbers 7, isolated refrigerant vapour enters condenser 8 through refrigerant vapour bridge tube 14 in the vapour liquid separator 3, condensed into water as refrigerant by the water quench in the heat-transfer pipe, enter evaporimeter 10 through the flow controller throttling, in evaporimeter 10, absorb the heat of heat-transfer pipe inner cold water and flash to water vapour, absorbed by the concentrated solution of inflow absorber 7, the absorption heat that produces is taken away by the cooling water in the heat-transfer pipe, solution concentration reduces and becomes weak solution, weak solution absorbs the heat temperature rising of concentrated solution after weak solution carrier pipe 12 is got back to generator 1 by solution heat exchanger 9 again, self temperature reduces behind the Cold water supply water as refrigerant heat in evaporimeter 10 heat-transfer pipes, become low-temperature cold water, recycle for air-conditioning temperature-reducing.Cooling water temperature in absorber and the condenser heat-transfer pipe raises by after cooling tower 15 coolings, enters absorber 7 again and recycles, and flow controller 5 can cut off the pressure between generator 1 and the absorber 7, and the liquid level difference at U type pipe two ends is its pressure differential.Liquid level meter 11 is used for regulating the liquid level of generator, and the injection rate of definite lithium-bromide solution.

When heating, as shown in Figure 5 cooling water system is closed.When isolated refrigerant vapour is flowed through condenser 8 in the vapour liquid separator 3, because cooling water closes and be not cooled, and directly enter evaporimeter, the cold water in the heating heat-transfer pipe makes it to become hot water, uses for heating.The refrigerant vapour of meeting after cold is condensed into water as refrigerant, falls into base of evaporator, inflow absorber 7, be mixed into weak solution with the concentrated solution of separating back time absorber, after solution heat exchanger 9 and concentrated solution heat exchange temperature raise, enter generator 1 and be heated once more, so circulation is more than.Heat circulation time, because generator 1 is very little with absorber 7 pressure at two ends differences, the liquid level difference at flow controller 5U type pipe two ends obviously reduces, and concentrated solution can directly be back to absorber 7 by flow controller 5.
