(54) ХОЛОДИЛЬНАЯ УСТАНОВКА(54) REFRIGERATING INSTALLATION

1one

Изобретение относитс к холодильной технике, а точнее к холодильным установкам дл ускоренных испытаний холодильного оборудовани судна.The invention relates to refrigeration equipment, and more specifically to refrigeration units for accelerated testing of the refrigeration equipment of a vessel.

Известны холодильные установки, содержащие контур циркул ции хладагента и установленные в нем компрессор, конденсатор с магистралью охлаждйюпхей воды, снабженной насосом, и испаритель с линией хладоносител , снабженной насосом и расшири- . тельным бачком, причем электродвигатель компрессора и обоих насосов снабжены пусковым устройством 1.Refrigeration units are known that contain a refrigerant circuit and a compressor installed therein, a condenser with a cooling water line equipped with a pump, and an evaporator with a refrigerant line equipped with a pump and expanded. tank, and the compressor motor and both pumps are equipped with a starting device 1.

Недостаток известных установок заключаетс в TOMj что их нельз использовать дл ускоренных испытаний холодильного оборудовани судна. Имеющего электроэнергетическую систему, вследствие необходимости проведени дополнительных работ, как опрессовка соединительных элементов после монтажа, зар дка хладоносителем и др.A disadvantage of the known installations is the TOMj that they cannot be used for accelerated testing of the refrigeration equipment of the vessel. Having an electric power system, due to the need for additional work, such as crimping connecting elements after installation, charging with a coolant, etc.

Цель изобретени - использование холодильной установки дл ускоренных испытаний холодильного оборудовани судна.The purpose of the invention is to use a refrigeration unit for accelerated testing of the refrigeration equipment of a vessel.

, Поставленна цель достигаетс тем, что магистраль охлаждающей воды и лини хладоносител снабжены съемными гибкими щлангами, а холодильна установка размещена на подвижной платформе, и ее пусковое устройство подключено к электроэнергетической системе судна.The goal is achieved by the fact that the cooling water line and the coolant line are equipped with removable flexible hoses, and the refrigeration unit is located on a mobile platform, and its starting device is connected to the ship’s electrical power system.

На чертеже схематично представлена предлагаема установка.The drawing shows schematically the proposed installation.

Она содержит компрессор 1, конденсатор 2 с магистралью 3 охлаждающей воды, снабженной Насосом 4, испаритель 5 с линией 6 хладоносител , снабженной насосом 7 и расширительнцм бачком 8, съемные гибкие щланги 9-12, платформу 13 и вентили 14-21.It contains a compressor 1, a condenser 2 with a cooling water line 3 equipped with a Pump 4, an evaporator 5 with a coolant line 6 equipped with a pump 7 and an expansion tank 8, removable flexible hoses 9-12, platform 13 and valves 14-21.

Установка работает следующим образом. Вс установка транспортируетс и устанавливаетс вблизи судна. С помощью съемных щлангов 9 и 10 установка быстро соедин етс с холодильным оборудованием судна , а щлангов 11 и 12 - с источником охлаждающей воды. После чего холодильноеThe installation works as follows. The entire installation is transported and installed near the vessel. With the aid of detachable sleeves 9 and 10, the installation is quickly connected to the ship’s refrigeration equipment, and the hoses 11 and 12 to the cooling water source. Then refrigerated

Claims

20, the vessel’s equipment is filled with a coolant and, in order to compensate for volume expansions, a expansion tank 8 is connected to it via valve 7. Then pumps 4 and 7 are turned on and a compressor is started up, which sucks the refrigerant vapor from the evaporator 5 and pumps them into the condenser 2, in which they turn into a liquid state. After throttling the liquid refrigerant, it boils in the evaporator 5 at low pressure, producing a cooling effect. The temperature of the coolant is maintained within the prescribed limits. The invention makes it possible to accelerate the testing of refrigeration equipment of the vessel, as well as to keep the refrigeration unit mounted on the vessel itself from wear. Claims: A refrigeration unit comprising a refrigerant circuit and a compressor installed therein, a condenser with a cooling water line equipped with a pump, and an evaporator with a coolant line equipped with a pump and an expansion tank, and the motors of the compressor and both pumps are equipped with a starting device featuring that for the purpose of using the refrigeration unit for accelerated testing of the refrigeration equipment of a vessel with an electric power system, the cooling line th water and coolant lines have removable flexible hoses and the cooling system is placed on a movable platform, and its trigger device is connected to the electric power system of ship.
