(54) ТЕПЛОВОЙ НАСОС ХОЛОДИЛЬНОЙ УСТАНОВКИ(54) HEAT PUMP REFRIGERATING INSTALLATION

II

Изобретение относитс к холодильной технике, а более конкретно - к комбинированным устройствам дл комплексного получени тепла и холода, и предназначаетс дл использовани 5 в сельском хоз йстве и молочной промьшшенности.The invention relates to refrigeration technology, and more specifically to combined devices for the integrated production of heat and cold, and is intended for use 5 in agriculture and dairy industry.

По основному авт.ев, № 215239, известен тепловой насос холодильной установки, содержащий испаритель, 10 сообщенный с компрессором, нагнетающим сжатый хладагента в конденсатор, охлаждаемый прбточной водой, мезвду конденсатором и испарителем включен двухсекционный теплообменник, одна 5 секци которого соединена с конденсатором дл получени гор чей воды, а друга -°с испарителем дл производства холода.According to the main author, No. 215239, a refrigeration unit heat pump is known, which contains an evaporator, 10 communicated with a compressor, forcing a compressed refrigerant into a condenser, cooled with water, a mezvdu condenser and an evaporator, a two-section heat exchanger is connected, one 5 section of which is connected to a condenser to obtain hot water, and the other - with an evaporator to produce cold.

На практике нередко по вл етс 20 необходимость получать кроме лед ной и теплой также и гор чую воду. Дл этой цели приходитс примен ть дополнительный электроподогрев или другой вид подогрева теплой воды, получае- i25 мой с помощью теплового насоса, что св зано с подводом дополнительного источника энергии.In practice, it is often necessary to obtain hot water in addition to ice and warm water. For this purpose, additional electric heating or another type of warm water heating, obtained by using a heat pump that is connected with the supply of an additional energy source, must be used.

Цель изобретени - повышение экономичности установки.30The purpose of the invention is to increase the efficiency of the installation.

Поставленна цель достигаетс тем, что между компрессором и конденсатором установлен форконденсатор, система охлаждени которого подсоединена к трубопроводу слива проточной воды .из конденсатора.The goal is achieved by the fact that a pre-condenser is installed between the compressor and the condenser, the cooling system of which is connected to the drain water pipeline from the condenser.

На чертеже изображена принципиальна схема тепловозго насоса холодильной установки.The drawing shows a schematic diagram of the diesel pump of a refrigeration unit.

Установка содержит испаритель 1, компрессор 2, форконденсатор 3, конденсатор 4, регулирующий вентиль 5, насос 6, секцию предварительного охлаждени 7, секцию окончательного охлаждени 8, трубы 9, 10 слива теплой И гор чей воды,.The installation contains an evaporator 1, a compressor 2, a precondenser 3, a condenser 4, a control valve 5, a pump 6, a pre-cooling section 7, a final cooling section 8, a pipe 9, 10 draining warm and hot water ,.

Тепловой насос холодильной установки работает следующим образом.The heat pump of the refrigeration unit operates as follows.

Claims

From the condenser 4 through the control valve 5, the refrigerant enters the evaporator 1, where it boils as a result of heat exchange with the coolant. The gaseous refrigerant enters compressor 2, where pressure and temperature rise as a result of compression. The hot vapor from the compressor enters the precondenser 3 and is cooled to a temperature close to the dew point, returning heat to the water coming from the condenser. After the precondenser 3, the refrigerant vapor enters the condenser 4, where it is finally cooled and condensed. The liquid product is fed to the pre-cooling section 7, where the product is pre-cooled by running water, after which it enters the final cooling section 8, where it is finally cooled by heat exchange with the coolant. The coolant circulates in a closed circuit between the evaporator 1 and the final cooling section 8 using a pump b. The flow water that has passed the pre-cooling section 7 is poured into the condenser 4, where it is heated to the S-IOC temperature below the condensation temperature and through the pipe 9, a spruce of warm water is discharged to the consumer. A portion of the warm water at the exit of the condenser 4 is directed to the for-condenser 3. Hot water through the drain pipe 10 is directed to the consumer of hot water. The application of the invention allows for those. At the same time, it costs energy to produce water, the production of which in normal conditions requires additional expenditure of fuel or electricity. Formula of the invention Heat pump of the refrigeration unit according to the author. St. I 215239, characterized in that, in order to improve efficiency, a forcondenser is installed between the compressor and the condenser, the cooling system of which is connected to the pipeline to drain the running water from the condenser.
