(54) ТЕПЛООБМЕННОЕ УСТРОЙСТВО(54) HEAT EXCHANGER

1one

Изобретение относитс к теплотехнике и может быть использовано в теплообменных устройствах с промежуточным теплоносителем .The invention relates to heat engineering and can be used in heat exchange devices with an intermediate coolant.

Наиболее близким к предлагаемому вл етс теплообменное устройство, содержащее испаритель, верхн часть которого соединена циркул ционными трубами с нижней частью расположенного над ним конденсатора 1.Closest to the present invention, there is a heat exchange device comprising an evaporator, the upper part of which is connected by circulation pipes to the lower part of a condenser 1 located above it.

Недостатком известного устройства вл етс невозможность повышени экономичности за счет осуществлени теплообмена либо с конденсатором, либо с испарителем в зависимости от необходимости утилизации либо холода, либотепла.A disadvantage of the known device is the impossibility of increasing efficiency by performing heat exchange either with a condenser or with an evaporator, depending on the need for disposal or cold or heat.

Цель изобретени - повышение экономичности .The purpose of the invention is to increase efficiency.

Указанна цель достигаетс тем, что испаритель и конденсатор сообщены циркул ционными трубами через кожух дополнительного кожухотрубного теплообменника, а на циркул ционных трубах выше и ниже последнего дополнительно установлены запорные вентили.This goal is achieved by the fact that the evaporator and the condenser are communicated by circulation pipes through the casing of an additional shell-and-tube heat exchanger, and shut-off valves are additionally installed on the circulation pipes above and below the latter.

На чертеже изображена схема теплообменного устройства.The drawing shows a diagram of the heat exchange device.

Теплообменное устройство содержит испаритель 1, верхн часть которого соединена циркул ционными трубами 2 с нижней частью расположенного над ним конденсатора 3, причем испаритель 1 и конденсатор 3 сообщены через кожух кожухотрубного теплообменника 4, а на циркул ционных трубах 2 выше и ниже теплообменника 4 установлены запорные вентили 5 и 6. to Устройство работает следующим образом.The heat exchange device contains an evaporator 1, the upper part of which is connected by circulation pipes 2 with the lower part of the condenser 3 located above it, the evaporator 1 and the condenser 3 communicating through the shell of the shell-and-tube heat exchanger 4, and on the circulation pipes 2 above and below the heat exchanger 4 shut-off valves are installed 5 and 6. to The device operates as follows.

Через трубы кожухотрубного теплообменника 4 пропускают, например, воздух, подаваемый дл вентил ции.For example, air supplied for ventilation is passed through the pipes of the shell-and-tube heat exchanger 4.

Claims

During the cold period, when the jacket needs to be heated, exhaust air 1 through the evaporator tubes, boiler exhaust gases or circulating water, which evaporate the heat transfer fluid filling the evaporator housing 1, pass through the open valves 5 on the shell and tube pipes. heat exchanger 4, transferring heat to the supply air. During the warm period, the air in the shell-and-tube heat exchanger 4 is cooled, switching it to work as an evaporator paired with a condenser 3, in which, for example, the air supplied to the boiler units is heated. At the same time, valves 5 are closed, valves b are open, and the shell of the shell-and-tube heat exchanger 4 is filled with an intermediate boiling heat carrier. During the period when the air supplied to the ventilation is not required to be heated or cooled, the air supplied to the boiler units is heated in the condenser 3, and the waste heat is utilized in the evaporator 1 when the valves 5 and 6 are open. The proposed device allows to increase the economy through year-round disposal waste heat. The invention includes a heat exchange device containing an evaporator, the upper part of which is connected by circulation pipes to the lower part of a condenser located above it, characterized in that, in order to increase efficiency, the evaporator and the condenser are communicated by circulation pipes through the casing of an additional shell-and-tube heat exchanger and The pipes above and below the latter additionally installed shut-off valves.
