(54) ХОЛОДИЛЬНЫЙ АГРЕГАТ(54) REFRIGERANT UNIT

1one

Изобретение относитс к холодильной технике, в частности к бессальниковым компрессионным холодильным агрегатам.The invention relates to refrigeration engineering, in particular to glandless compression refrigeration units.

Известны холодильные агрегаты, содержащие корпус с боковыми крышками и раз-мещенный в нем бессальниковый компрес - 5 сор с электроприводом, а также вентил тор с электродвигателем и конденсатор воздушного охлаждени 1.Refrigeration units are known, comprising a housing with side covers and a non-stuffing compressor - 5 electrically-controlled litter located in it, as well as a fan with an electric motor and an air-cooled condenser 1.

Недостатком известных холодильных агрегатов 5Гвл етс их громоздкость вследствие IQ больших габаритов электродвигател вентил тора .The disadvantage of the known refrigeration units 5G is their bulkiness due to the IQ of large dimensions of the fan motor.

Целью изобретени вл етс повышение компактности.The aim of the invention is to increase the compactness.

Указанна цель достигаетс тем, что ротор электродвигател вентил тора раз- 15 мещен по оси статора электропривода компрессора , при этом бокова крышка корпуса со стороны вентил тора выполнена в виде стакана и служит экраном между указанными ротором и статором.joThis goal is achieved by the fact that the rotor of the fan electric motor is located along the stator axis of the compressor electric drive, while the side cover of the case on the fan side is made in the form of a glass and serves as a screen between the indicated rotor and stator.jo

На чертеже схематично представлен пред-, лагаемый агрегат.The drawing schematically shows the pre-, lagging unit.

Агрегат содержит корпус 1 с боковыми крыш1 ами 2 и 3 и размешенный в нем бессальниковый компрессор 4 с электроприводом , имеющим статор 5 и ротор 6, вентил тор 7 с ротором 8 На одном валу 9 и конденсатор 10 воздушного охлаждени .The unit comprises a housing 1 with side covers 2 and 3 and a sealed compressor 4 with electric drive, having a stator 5 and a rotor 6, a fan 7 with a rotor 8 On one shaft 9 and an air-cooled condenser 10.

Кроме этого, на чертеже показано центрирующее устройство 11, общее дл вала 9 вентил тора 7 и коленчатого вала 12 компрессора 4, подшипники 13 и 14 и обща рама 15.In addition, the drawing shows a centering device 11, common to the shaft 9 of the fan 7 and the crankshaft 12 of the compressor 4, bearings 13 and 14, and a common frame 15.

Бокова крышка 3 выполнена в виде стакана 16, вогнута часть которого введена в статор 5 электродвигател компрессора 4. В этой части стакана 16 размещен ротор 8, привод щий во вращение вентил тор 7. Таким образом, вращение ротора 8 и соответственно вентил тора 7 осуществл етс магнитным полем, возникающим в стато1:е 5 электропривода компрессора 4.The side cover 3 is made in the form of a cup 16, the concave part of which is inserted into the stator 5 of the compressor 4 electric motor. In this part of the cup 16 a rotor 8 is placed, causing the rotation of the fan 7. Thus, the rotation of the rotor 8 and, accordingly, of the fan 7 is performed the magnetic field arising in stato1: e 5 of the compressor electric drive 4.

Агрегат работает следующим образом.The unit works as follows.

Claims

When an alternating electric current is applied to the stator 5, a rotating magnetic field arises, which induces an electromotive force in the rotors 8 and 6. In this case, the rotor 6 drives the compressor 4 through the crankshaft 12, and the rotor 8 through the shaft 9 - the fan t9r 7. Refrigerant pairs low pressure is sucked in by compressor 4 from an evaporator (not shown) and injected into condenser 10, in which it is turned into a liquid. The released heat of condensation is carried away by the air blown through the condenser 10 by the fan 7. After the throttling, the liquid refrigerant that is formed enters the evaporator, in which the cooling effect is boiling at low pressure. The economic efficiency of the invention is reflected in the reduction of the metal consumption of the unit and an increase in its compactness due to the placement of the rotors of the compressor electric drive and the fan in the common stator. Claims: The refrigeration unit comprising a housing with side flaps and a vacuum-free motor-driven compressor located therein, as well as a fan with an electric motor and an air-cooled condenser, characterized in that, in order to increase its compactness, the rotor of the fan motor is placed along the stator axis of the electric drive the compressor, the side cover of the housing on the fan side is made in the form of a glass and serves as a screen between the rotor and the stator.
