Background technology

Along with the sharp increase of world's conventional energy resource consumption and going from bad to worse of earth environment; make people more and more pay attention to the saving of the energy and the protection of environment; the Montreal protocol amendment of 1985 " Vienna Convention for the Protection of the Ozone Layer ", nineteen ninety and international pacts such as " Copenhagen amendments " in 1992, the restriction of rules make that the substitution problem of CFC (CFCs) and HCFC (HCFCs) is urgent day by day in the world.Adsorptive refrigeration technology has adapted to the requirement of the current energy and harmonious development.It can adopt the solar energy of low energy densities and used heat to drive, not only the anxiety supply of the energy is played and slowed down effect, and do not use the chloro-fluoro-carbon kind cold-producing medium, no CFCs problem, also not having greenhouse effects, is one of green refrigeration method of 21 century CFC alternative s compression-type refrigeration.But this technology is not moved towards the commercialization marketization for many years all the time.Wherein the cooling to cold-producing medium is a key technology, especially how to realize effectively that in the stages such as the formation of cold-producing medium, adsorbent and cold-producing medium liquefaction cooling not can solve always.

Summary of the invention

The purpose of this utility model provides a kind of chloro-fluoro-carbon kind cold-producing medium that do not use, and no CFCs problem does not have greenhouse effects yet, the using waste heat from tail gas of internal combustion engine refrigeration unit cooling device of energy-conserving and environment-protective.

For achieving the above object, the technical scheme of employing is as follows:

A kind of using waste heat from tail gas of internal combustion engine refrigeration unit cooling device, be characterized in: cooling device comprises water pump, hydraulic pipeline, reaches magnetic valve, hydraulic pipeline lays respectively at refrigeration unit and holds the smoke box two ends, water pump is positioned at an end of hydraulic pipeline, magnetic valve is positioned on the hydraulic pipeline, and it is by automatic controlling system.

In such scheme, the cooling device that holds the smoke box cooling adopts down, on go out overflow type and force to cool off.

Each generator causes cold-producing medium desorption and cooling to cause cold-producing medium absorption the time all can produce pressure being heated, because the effect of check-valves, cold-producing medium is done one-way movement in the refrigerant transfer pipeline.

The utility model adopts water as cooling medium, raw material is obtained easily, especially for ship, can directly water pump be placed below the horizontal plane, prop up in the running at ship and can change cooling medium endlessly, adopt overflow type force the type of cooling work period short, efficient is high, refrigerating capacity is big.

The utility model is described in further detail below in conjunction with drawings and Examples.
