Description

The invention relates to refrigeration engineering, namely to absorption refrigeration units, used primarily for air conditioning in a mine,

The purpose of the invention is to increase operational reliability.

The drawing shows a schematic representation of the proposed refrigeration unit.

It contains generator 1, absorber 2, heat exchanger-regenerator .3, pump 4 strong solution, pump 5 weak solution, condenser 6, evaporator 7, line 8 strong solution, line 9 weak solution, line 10 liquid refrigerant, sump line 11, waste from a dewatering device, a hydraulic distributor 12 with rotating rotating chambers 13 and 14 and a movable piston 15, a receiver 16 heat pipes 17, the evaporation sections 18 of which serve as the heat-exchange surface of the absorber 2, and the condensation zones 19 are enclosed in discharge line 1 mine 21 and pipelines 22 and 23,

A generator 1 with a condenser 6, a pump 4 of strong solution and a heat exchanger-regenerator 3 are placed on the surface of the shaft 21, and an absorber 2 with an evaporator 7, a pump 5 of a weak solution, a valve 12 and a receiver 16 are located at the depth of the shaft

The operation of the unit is carried out as follows.

08433, 2

In the generator 1, a weak solution is evaporated, the refrigerant vapors which are formed during this are condensed in the condenser 6, and the remaining strong

fi, the solution is supplied by pump 4 through the guide, the distributor 12 to the absorber 2, which irrigates the evaporation sections 18 of the heat pipes 17, the liquid refrigerant from the condenser 6 goes to the receiver 16, from where it is discharged to the evaporator 7, which boils under high vacuum, producing a refrigerating effect, cooling the coolant flowing through the evaporator 7 while cooling. The resulting low-pressure refrigerant vapor is absorbed by the strong solution in the absorber 2, and a weak solution is formed, which is supplied by the pump 5

20 through the hydraulic distributor 12 and the heat exchanger-regenerator 3 to the generator 1,. The absorption heat that is absorbed is diverted from the cooling water that washes the condensation zones 19 of the heat pipes 17 in the casing 20, the hydraulic distributor 12 consists of

rotating chambers 13 and 14, separated by a movable piston 15, alternately switching between each other line 8 and

30, pipe 22, as well as line 9 and pipe 23, while at the same time recirculating the solution in the absorber 2 and feeding the strong solution 1 to the absorber 2

d; and back a weak solution from absorber 2 to generator I,
