Vehicle-mounted refrigeration equipment driven by engine waste heat

Abstract

The invention relates to a vehicle-mounted refrigeration equipment driven by engine waste heat. The vehicle-mounted refrigeration equipment comprises a generator, a condenser, an evaporator, an absorber, a generator heating circulation loop arranged between the generator and the engine, a solution loop and a refrigerant water loop, wherein the solution loop comprises a concentrated solution channel and a dilute solution channel which are respectively provided with a pump and an electromagnetic valve. Since the concentrated solution channel and the dilute solution channel are directly arranged between the generator and the absorber in the solution loop and the pump and the electromagnetic valve are respectively arranged on the concentrated solution channel and the dilute solution channel, linked control between a high-pressure region and a low-pressure region can be realized by the electromagnetic valve and the pump, thus control based on difference of liquid level of a U-shaped tube in the prior art can be avoided; relative to the control mode of the U-shaped tube, the vehicle-mounted refrigeration equipment has the advantage of smaller size, therefore the equipment is more suitable for being installed on the bodies of large and medium-sized vehicles.

Description

【Technical field】 [0001] The invention relates to a vehicle-mounted refrigerating device, more specifically, relates to a vehicle-mounted refrigerating device adapted to large and medium-sized vehicles driven by engine waste heat. 【Background technique】 [0002] In the prior art, there are usually two ways to realize refrigeration technology using thermal energy: absorption type and adsorption type. These two kinds of refrigeration equipment are larger than the compression refrigeration equipment widely used at present, and the adsorption refrigeration equipment is much larger than the absorption refrigeration equipment. If the waste heat of the engine is used as the driving force to provide cold energy to the vehicle, from the perspective of volume and weight, the absorption refrigeration technology has advantages. For cars, light and miniature vehicles, there is no extra space under the chassis, roof and engine compartment, only large and medium-sized passenger cars, engi...

AI Technical Summary

Problems solved by technology

[0009] The main technical problem to be solved by the present invention is to provide a smaller volume and more suitable for large and medium-sized vehicles, aiming at the defect that the heat-driven absorption refrigeration equipment in the prior art cannot be centrally installed on large and medium-sized vehicles due to its large volume.
