Abstract

PURPOSE:To eliminate necessity for use of any sturdy common table by installing a plurality of compressors with small capacity on the same housing, and by driving them by a single prime mover or an electric motor. CONSTITUTION:A plurality of compressors with small capacity 1 are held by a housing 2, which is fixed to a prime mover 3. The output shaft 4 of this prime mover 3 is connected to pulleys 6' of those compressors 1 through a pulley 6 and a belt 5. Accordingly the compressors 1 are driven simultaneously by this single unit of prime mover 3 to cause elimination of the use of any common table, and they can be mounted on a floor 12 etc. firmly without such a common table as solely designed for installation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compression device, and more particularly, to a compression device that obtains a desired output by driving a plurality of small capacity compressors held in a common housing by one prime mover or electric motor. Regarding equipment.

As is well known, in the past, compressors for mechanical refrigeration systems and the like have used compressors with outputs corresponding to each output request, and in many cases, each compressor has a corresponding output. Each machine was used connected to a single prime mover or electric motor.

In response to a wide range of output requirements, the number of types of compressors has inevitably increased, causing an increase in the average price of each compressor.

Moreover, each compressor was driven by a prime mover with an output far greater than the required output, which resulted in various undesirable problems such as increased price, increased weight, vibration, and noise. It was occurring.

In addition, in order to connect the prime mover or electric motor and the compressor, the axes of both must be aligned or aligned, so they must be fixed on a common stand made of strong steel.However, this In this way, it is difficult to align the axes of the two correctly, requiring skill to install, and not only requires readjustment during operation, but also increases the price and generates vibration.
Various undesirable problems, such as increased weight and increased equipment size, have also occurred due to the connection between the prime mover and the compressor.

The object of the present invention is to solve the above-mentioned conventional problems, and to provide a compression device that is inexpensive and lightweight, generates little vibration and noise, does not require a common frame, and can be easily used at a desired location. It is to provide.

In order to achieve the above object, the present invention includes a plurality of small capacity compressors mounted on a common nozzling and driven by a single prime mover or electric motor.

Hereinafter, the present invention will be described in detail with reference to Examples.

FIG. 1 shows an example of part 1 of the present invention. As is clear from FIG. 1, in the present invention, a plurality of small capacity compressors 1 are held in a common housing 2, and housing 2
is fixed to the prime mover B. 4 output shafts of prime mover A,
It is connected to the pulleys 6' of the plurality of small capacity compressors 1 through the pulley 6 and belt 5, and the plurality of compressors 1 are simultaneously driven by one prime mover 3.

As mentioned above, in conventional compression devices, one compressor is generally driven by one prime mover, but the present invention drives multiple small capacity compressors by one prime mover, and performs small capacity compression. Respond to output demands by increasing or decreasing the number of machines.

Therefore, it is no longer necessary to prepare a compressor with a variety of forces as in the past, and the price of the compressor will be significantly reduced by mass production. Moreover, since it is possible to use a compressor that is produced in large quantities in a streamlined mass production factory, such as a compressor for an automobile's car cooler, the price is much lower than that of conventional compressors.

Therefore, the number of compressors 1 to be used is set to the optimal value,
Able to respond to output requests without waste.

For example, FIGS. 2(a) and 2(b) show that four and six compressors 1 are installed in the nozzle 2, respectively.
An example is shown in which the output shaft 4 of the prime mover is connected to the belt 5 via 7, but it is clear from the example shown in Fig. 2 that the number of small capacity compressors can be selected as appropriate in response to output requirements. .

Moreover, by using a magnetic clutch in all or part of the small capacity compressor, it becomes possible to change the number of operating compressors to closely follow load fluctuations. Furthermore, since staggered operation is also possible, the problem of torque at startup is also solved. This was not possible with conventional equipment using a single compressor.

FIG. 3 shows an example of a mode in which the small capacity compressor 1 is held in the housing 2, and four compressors 1 are held in the housing 2.

As is clear from FIG. 3, the housing 2 is provided with a slot 7, and each compressor 1 is connected to the slot 7.
It is fixed to the housing 2 by a fixing bolt 8 at this portion.

Therefore, not only can the position of each compressor 1 be adjusted accurately, but also it is easy to remove and replace a malfunctioning compressor. Also, it is no secret that it is easy to exchange and exchange Pels.

Conventional compression equipment uses a single large-capacity compressor, so in the event of a failure, the compressor loses its function completely, and the cost of repair or replacement is high.

However, in the present invention, as in n1-1 above, a plurality of small-capacity compressors are used, and the output request is met by their total output. Therefore, even if one of the compressors breaks down, it is possible to continue operating with the remaining compressor, and the cost and effort required to replace a broken small-volume compressor can be reduced compared to conventional large-capacity compressors. It is much cheaper and easier than replacing it.

In addition, in FIG. 6, in order to show the cross-sectional shape of the conduit (ladder to the refrigerant gas collection) 9 through which the heat medium passes (ζ, a part 10 of the conduit 9 is excluded, but the actual conduit It goes without saying that 9 is not disconnected in this way, and is connected to the evaporator and the condenser through the connections 11 and 11', respectively.

As is clear from FIGS. 1 and 6, in the present invention, a number of small capacity compressors 1 are attached to a common housing 2, and this housing 2 is directly attached to a prime mover or an electric motor.

Therefore, as shown in FIG. 1, there is no need for a common pedestal for the prime mover and the compressor, and they can be used while being fixed on the floor 12 or the like without a common pedestal.

Conventionally (';t, it is difficult to adjust the axis of the prime mover and compressor,
For this reason, it was necessary to place both on a strong common pedestal, and to provide a vibration isolation mechanism between this common pedestal and the installation floor.

Therefore, the price increase and weight increase alone will cause
There was a problem in that the vibration isolation conditions had to be carefully considered each time depending on the conditions of the location where the device was installed, and the installation location was also limited.

The present invention does not require such a common frame at all, and is much easier to install on the installation floor, so it can be used in places where installation was conventionally difficult, even if the floor is slightly sloped. It can be used for various purposes such as air conditioning equipment and cold offshore equipment.

As is clear from the above description, the present invention solves various problems that conventional devices had, namely, aligning the axes of the prime mover and the compressor.

A strong common mount is required, and installation locations are limited.

It is heavy and expensive. It is extremely useful as it solves all the problems that can easily cause noise and vibration.
