Abstract
The utility model relates to an absorption-type chiller-heater, in particular to a super-effective direct-fired lithium bromide absorption-type chiller-heater, comprising a lower barrel composed of an evaporator and an absorber and an upper barrel composed of a condenser and a low pressure generator. A direct-fired high pressure generator is connected with the burner. The direct-fired high pressure generator and the lower barrel are communicated with a connecting distributing pipe via a solution pump and a low temperature exchanger. The direct-fired high pressure generator and the upper barrel are communicated with the connecting distributing pipe via a high temperature heat exchanger. An air pre-heater is provided on a smoke outlet of the high pressure generator, while an air inlet of the burner passes though the air pre-heater. The utility model can adequately utilize the smoke at 200Deg. C emitted from the high pressure generator to pre-heat the air coming into the burner to improve the burning efficiency effectively, thereby improving the capacity factor COP of the whole unit, saving energy and reducing the working cost. In addition, the utility model is applicable to various direct-fired absorption- type chiller-heaters.
Description
Technical field:
The utility model relates to a kind of direct fired absorption refrigeration machine.
Background technology:
Lithium-bromide absorption-type refrigerating machine is to be refrigerant with water, and lithium-bromide solution is an absorbent, directly burns the heat that produces or other used heat as thermal source with steam, hot water, oil and gas, and the principle that utilize evaporation, absorbs realizes freezing.Currently used lithium-bromide absorption-type refrigerating machine can be divided into single-action, economic benefits and social benefits, triple effect or multiple-effect type Absorption Refrigerator by the degree of energy utilization.Common double-effect absorption refrigerating machine is to use steam (pressure 2.5-8kg/cm as shown in Figure 2 on the market
2.G), oil and gas directly burns the heat that produces as thermal source, is respectively steam type, direct combustion type double-effect absorption refrigerating machine.Traditional direct combustion double effect absorption cold warm water machine exhaust gas temperature is than higher, and the heat loss of flue gas is bigger, and the capacity factor COP of unit is lower.
Summary of the invention:
The utility model purpose is to overcome the big problem of above-mentioned direct fired absorption refrigeration machine heat loss, and a kind of ultra high efficiency direct-burning type lithium bromide absorption type cold warm water machine is provided, and improves the capacity factor COP of product, energy savings, the efficiency of combustion that improves.
The technical scheme that the utility model is adopted for achieving the above object is: ultra high efficiency direct-burning type lithium bromide absorption type cold warm water machine, unit comprises doffing and top cylinder, doffing is made of evaporimeter and absorber, top cylinder is made of condenser and low pressure generator, Direct Fired High Pressure Generator connects burner, Direct Fired High Pressure Generator and doffing are through solution pump, low-temperature switch is communicated with by connecting pipings, Direct Fired High Pressure Generator is communicated with by connecting pipings through high-temperature heat exchanger with top cylinder, in high pressure generator flue gas source an air preheater is set, the burner air air inlet pipe is passed air preheater.
Two groups of paths are arranged in the described air preheater, and one group of path is the fume waste heat path of discharging from high pressure generator burning back, and another group path is the air flue that enters burner combustion from the external world.
The beneficial effects of the utility model are: can make full use of about 200 ℃ flue gas that high pressure generator is discharged, the air that enters burner is carried out earlier entering burner combustion again after the preheating, can effectively improve efficiency of combustion, thereby improved the capacity factor COP of whole refrigeration machine unit, energy savings, reduce operating cost, the utility model is applicable to various direct fired absorption refrigeration machines, belongs to the new technology of sustainable development.
Description of drawings:
Fig. 1 is existing direct combustion double-effect absorption refrigerating machine structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment:
Ultra high efficiency type lithium bromide absorption cooling and warming water machine as shown in Figure 2, unit comprises doffing and top cylinder, doffing is made of evaporimeter 1 and absorber 2, top cylinder is made of condenser 3 and low pressure generator 4, Direct Fired High Pressure Generator 5 connects burner 10, Direct Fired High Pressure Generator and doffing are through solution pump 9, low-temperature switch 6 is communicated with by connecting pipings, Direct Fired High Pressure Generator and top cylinder are communicated with by connecting pipings through high-temperature heat exchanger 7, cryogenic fluid pump 8 is installed on the pipeline, air preheater 11 and air blast 12 in unit, air preheater is installed on the high pressure generator, air preheater is totally two groups of paths, one group of path is the fume waste heat path of discharging from high pressure generator burning back, it is communicated with the high pressure generator exhanst gas outlet, another group path is the air flue that enters burner combustion from the external world, and air blast is equipped with in import department, and the burner air inlet is connected in the exit.In the unit running, come preheating to be about to enter the air of burner by the fume waste heat that utilizes high pressure generator to discharge, can effectively improve the burning quality of combustion air in burner, and then improve the efficiency of combustion of unit, reach energy-conservation and utilize the purpose of used heat environmental protection.
