Description

Centrifugal refrigerating machines
Technical field
The utility model is related to art of refrigeration units, especially a kind of centrifugal refrigerating machines.
Background technology
In centrifugal refrigerating machines system, lubricating system is one of its important group parts, and lubricating system generally comprises oil Case, oil pump, filter, oil cooler (cold oil device), fuel reserve tank, oil return apparatus etc..When due to lubricating oil by bearing, gear, On the one hand these components are lubricated, ensure its reliability service, on the other hand take away heat caused by the operating of these components, Ensure its safe operation.In the process, lubricating oil temperature will be higher and higher, directly influences lubricating oil viscosity, Jin Erying The lubricant effect to bearing, gear is rung, and is nowadays to lead to part refrigerant in fuel reserve tank to cool down lubricating oil, is increased The power consumption for having added compressor, reduces unit performance.
Utility model content
In order to solve the above-mentioned technical problem, a kind of centrifugal cold water being carried out cooling to lubricating oil using cooling water is provided Unit.
A kind of centrifugal refrigerating machines, including condenser, cooling tower and fuel reserve tank, the condenser connect with the cooling tower It is logical to form cooling water circulation loop, cooling structure is provided in the fuel reserve tank, the cooling structure is connected serially to the cooling water In circulation loop.
The cooling structure is arranged in parallel with the condenser.
The cooling structure is heat exchange coil, and the water inlet end of the heat exchange coil is connected to the water inlet end of the condenser, Water outlet is connected to the water outlet of the condenser.
The water inlet end of the heat exchange coil is provided with filter.
Size of the liquid level more than the heat exchange coil in the liquid level direction in the liquid reserve tank.
The water outlet of the heat exchange coil is provided with solenoid valve.
The heat exchange coil is external screw thread heat exchanger tube.
Centrifugal refrigerating machines provided by the utility model can be directly sharp by the way that heat exchange coil is arranged in fuel reserve tank Lubricating oil is cooled down with cooling water, compressed liquid refrigerants is not lost, directly by cooling tower by the heat of lubricating oil It dissipates, effectively improves unit performance.
Description of the drawings
Fig. 1 is the structural schematic diagram of centrifugal refrigerating machines provided by the utility model;
In figure:
1, condenser;2, cooling tower;3, fuel reserve tank;4, cooling structure;5, filter.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation The present invention will be further described in detail for example.It should be appreciated that specific embodiment described herein is only used for explaining this Utility model is not used to limit the utility model.
Centrifugal refrigerating machines as shown in Figure 1, including condenser 1, cooling tower 2 and fuel reserve tank 3, the condenser 1 with The connection of the cooling tower 2 forms cooling water circulation loop, and cooling structure 4, the cooling structure 4 are provided in the fuel reserve tank 3 It is connected serially in the cooling water circulation loop, the cooling structure 4 can carry out the lubricating oil in fuel reserve tank 3 using cooling water Heat exchange, and transferred heat to after cooling tower 2 using cooling water and radiated by cooling tower 2.
The cooling structure 4 is arranged in parallel with the condenser 1 so that the heat in the cooling structure 4 is directly by cold But in Water transport to the cooling tower 2.
The cooling structure 4 is heat exchange coil, and the water inlet end of the heat exchange coil and the water inlet end of the condenser 1 connect Logical, water outlet is connected to the water outlet of the condenser 1 so that part cooling water directly flows into described change by the cooling tower 2 It in hot coil, and is flow in the cooling tower 2 after exchanging heat in heat exchange coil, the cooling water after heat exchange is avoided to flow to condenser 1 In, cause the reduction of 1 efficiency of condenser.
The water inlet end of the heat exchange coil is provided with filter 5, to prevent impurity from entering in the heat exchange coil, causes to block up Plug.
Size of the liquid level more than the heat exchange coil in the liquid level direction in the liquid reserve tank so that institute It states heat exchange coil to be flooded completely with lubricating oil, the cooling water that guarantee enters in the heat exchange coil fully carries out heat with lubricating oil It exchanges.
The water outlet of the heat exchange coil is provided with solenoid valve.
The heat exchange coil is external screw thread heat exchanger tube, ensures the cleanliness factor of maximum heat exchange area and cooling water.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
