ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an adsorptive refrigerating device and, in particular, to an adsorptive refrigerating device utilizing the heat from the engine exhaust.
2. Description of the Prior Art
In current technology, fishermen need to carry a large amount of ice to keep caught fishes fresh for a long time when they go fishing in the sea. Since it takes very much electrical energy to make ice and keep ice in a low temperature environment, the ice is therefore expensive and very often short of supply. This can not guarantee or meet the need of proper fish storage on the boat. On the other hand, in spite of the fact that traditional adsorptive refrigerating devices have been proposed and are technically feasible, yet the refrigerating efficiency is low and the temperature fluctuates a lot. Thus there is no practical products on the market.
SUMMARY OF THE INVENTION
The present invention provides a fisherman refrigerating device using engine exhaust which takes the exhaust heat from a ship engine as the heat source to realize the adsorptive cyclical refrigeration and to produce ice for fish storage on the ship. This has the features of saving energy and good refrigerating effect without costing extra fuel and lowering the engine power.
The fisherman refrigerating device using engine exhaust according to the invention comprises a refrigerating tub which contains a storage bottle of coolant liquid ammonia and a condenser. The refrigerating tub has a heat-insulating box-type body and a removable lid. The body has a vaporizer, which comprises several closed tubes connecting in series with one end as the inlet and the other end as the outlet. The surface of each closed tube has heat conducting wings. The storage bottle comprises a heat-insulating bottle, a coolant inlet and a coolant outlet. The condenser comprises a water reservoir and a spiral tube in the water layer, wherein the water reservoir consists of an upper water outlet and a lower water inlet, and the spiral tube has an inlet and an outlet. The invention comprises two generators and the guiding pipes of which are connected to the spiral tube inlet of the condenser via corresponding stop valves, while the spiral tube outlet is connected to the inlet of the storage bottle under the condenser. The storage bottle outlet is connected with the inlet of the vaporizer via a flux control valve. The vaporizer outlet is connected to the guiding pipes of the two generators by two stop valves, respectively. The structure of the generator is that an engine exhaust pipe runs through the outer case and an inner pipe sits in the engine exhaust pipe. The chamber between the engine exhaust pipe and the inner pipe is filled with several inner tubes and calcium chloride as the adsorbent. The wall of the inner tube has several apertures, and one end of the inner tube is closed while the other open. The open ends of the inner tubes are connected to the guiding pipe from the chamber. The upper part of the outer case has a water inlet connector connecting to the porous sprinkling tube above the inner pipe, whereas the lower part of the outer case has a water outlet connector.
