Description of drawings
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is further described:
Refrigeration principle and the common steam formula cooling-water machine of the heat pipe type double-effect lithium bromide absorption type water chiller/heater that fume waste heat drives are basic identical, be high pressure generator without Steam Heating, but with fume waste heat as drive energy.In unit, cooling coil pipe (2) can use as cooling coil and heat(ing) coil respectively according to cold and heat supply mode difference, and circulating pump (3) also is to use as water supply pump and heat-exchanger pump respectively according to cold and heat supply mode difference.When adopting the system of ad hoc hot-water return (as Fig. 1), heat exchange of heat pipe (4) is delivered to the heat in the fume waste heat in the high pressure generator of double-effect lithium bromide absorption type water chiller/heater (1), is provided with common heat exchanger (5) in the high pressure generator.When producing hot water, heat exchange of heat pipe (4) is with part or all of heat transferred heat exchanger (5), and the hot-water return by supporting heat(ing) coil (2) and circulating pump (3) (this moment is as heat-exchanger pump) are formed provides heat or produces life hot water to the heating environment.Cold water and hot water be can produce simultaneously like this, also can cold water and hot water be alternately produced by the conversion of operating mode.When chilled water, its operation principle is identical.Cooling coil pipe (2), circulating pump (3) at this as chilled water circuit.Hot water and cold water adopt same loop (as Fig. 2), can alternately produce cold water and hot water by the conversion of operating mode.In general the type of heat pipe have multiple, for example variable heat conduction pipe, gravity assist type heat pipe, separate heat pipe, wick type heat pipe or the like, heat pipe of the present invention is gravity assist type heat pipe or separate heat pipe.
With a refrigerating capacity is 20 * 10
4Kcal/h, heating capacity are 17.1 * 10
4The double effect absorption water chiller/heater of kcal/h is an example: the entrance flue gas temperature scope is 250～500 ℃ usually, supposes that flue gas flow is 5000m
3/ h, heat exchange of heat pipe heat exchange efficiency＞90%, by heat exchange of heat pipe fume waste heat is recycled, the double effect absorption water chiller/heater can obtain the driving heat of 81.1kJ/h, and it is the hot water (domestic hot-water) that 7 ℃ cold water and outlet temperature are 60 ℃ that water chiller/heater can be produced outlet temperature.The form of go out according to cold water is specified/7 ℃/12 ℃ of inlet temperatures, cooling coil being determined in flow and application scenario; The form of go out according to hot water is specified/60 ℃/55.7 ℃ of inlet temperatures, heat(ing) coil being determined in flow and application scenario.
