Abstract

Usage: refrigeration engineering. SUMMARY OF THE INVENTION: an air cooler comprises a casing 2 with inside the evaporative sections 1 of the heat pipes and an additional heat exchanger 3 adjacent to the body 2, in which the condensing sections of these pipes are located, the evaporating sections 1 of the pipes being finned, the condensing sections are made of pipe tubes and the pipes are inclined to horizontal plane towards evaporative sections. The heat exchanger 3 is filled with salts of a eutectic concentration solution and is equipped with a finned coil 4 with nozzles 5 and b placed inside for supplying and discharging refrigerant. In this case, the condensation sections of the pipes pass through the cavity of the coil 4. 1 zp f-ly, 3 ill.

Liquid ammonia is available and supply pipe 5 and pacHpf are through pipes of the ZM8-evik. The ammonia produced in the industrial evaporation process is used to cool the eutectic solution in the additional heat exchanger 3, to condense the equal body § the co-compensation section 13 of the warm pipe 1. The cold is transferred to the air supplied by the fan 9 to the evaporation section 14 using the working medium of the tweed pipe 1. The rastaor is cooled to a temperature lower than with the direct cooling system, thereby providing a reserve of cold for subsequent operation. The evaporated aMMitiaK removes the bpc from the coil through the branch pipe 6. The mode of operation with the exergy of anergy. Ammonia supply disconnected. The air is cooled by using the accumulated cold solution. The transfer of thermal energy is carried out in the same way. The solution then heats up. Electricity is spent only on the drive of the fan 9,

For the return of the condenser of the condensing section 13 to the evaporator (section 14, heat pipes are split with an angle of inclination of 5-tp °.

The slope angle is determined from the limiting conditions of operability of the heat pipe. Decreasing the angle of inclination will result in

the whipping of the heat pipe. Increasing the angle of the pipe over Itf leads to

The main sections of the heat pipes are finned, the condensation ones are smooth-pipe, and the pipes are laid with a slope to the horizontal plane and to the side of the evaporation sections, and therefore, so as to increase the operational In order to reduce energy (consumption during periods of peak loads, the heat exchanger is filled with a saline solution of eutectic concentration and equipped with a finned coil located inside, with pipes for supplying and discharging refrigerant, and condensation sections of pipes pass through olost coil:.;
