Abstract

The invention relates to refrigeration. The goal is to increase the heating capacity and efficiency of the installation. The installation contains an absorption heat pump 1, having a Tonicy 2 heat generator, equipped with a fuel nozzle 3, a condenser 4, an adsorber 5, an evaporator 6, a heat exchanger 7, an economizer 8, pumps 9, 10, 11, an internal combustion engine 12 with an electricity generator 13 and a pipeline 14 air supply. The exhaust pipe 15 is connected to the furnace 2; the first gases of the engine 12. Economizer 8 is included in the intermediate cooling circuit before the evaporator 6 of pump 1. The heat carrier of the internal cooling circuit of the engine 12 cools the engine and transfers heat in the heat exchanger 7 to the coolant of the intermediate cooling circuit, which is additionally heated In the economizer 8, heat is transferred in the evaporator 6 of the pump 1. The heat received from the intermediate low-temperature circuit of the coolant is transferred to the adsorber 5 and the condenser 4 of the pump 1 external external view loop contour, 1 Il. cl

And the acquisition relates to refrigeration engineering, in particular to installations for the joint generation of thermal and electrical energy.

The purpose of the invention is to increase the heat output and efficiency of the heat and power installation.

The drawing shows a schematic diagram of the heat and power installation.

Thermal power plant contains absorption heat pump 1 with furnace of heat generator 2, equipped with fuel nozzle 3, condenser 4, absorber 5, evaporator 6, heat exchanger 7, economizer 8, circulation pump 9 of the intermediate cooling circuit, circulation pump 10 of the external circuit, pump 11 high-temperature coolant, engine 12 internal combustion generator 13 electricity. Pipelines for air inlet 14 and exhaust gas outlet 15.

The installation works as follows.

The internal combustion engine 12 drives the electric generator 13, the exhaust gases of the engine through pipeline 15 into the furnace of the generator 2 of the heat of the absorption heat pump 1, where the residual oxygen burns the fuel supplied by the nozzle 3, the coolant of the internal cooling circuit of the internal combustion engine 12 cools the engine and transfers heat in the heat exchanger 7 to the coolant of the intermediate cooling circuit, which is additionally heated in the economizer 8, which is located on its own gas cavity The exhaust pipe section 15, transfers the heat obtained in the evaporator 6 of the absorption heat pump 1, due to the unsatisfied working cycle of the absorption heat pump, the heat received from the intermediate low-temperature coolant circuit is transferred to the absorber 5 and the condenser 4 of the absorption heat pump to the heat carrier of the external high-temperature loop associated with the consumer heat.
