There are many kind of refrigerating units, according to the volume type compressor including the following kinds:
1. According to the shape of compressor which is volume, can be divided into piston type and rotary type two kinds, at present, the piston type including full close and semi closed type compressor and rotary type including screw and scroll compressor. Generally, the scroll compressor is known as full closed compressor.
2. According to the number compressor units is divided into two kinds: single refrigeration unit and parallel refrigeration unit.
3. According to the condensing unit, it divided into air cooling and water cooling Compressor Unit.
4. According to the cooling media, it divided into fluorine refrigeration unit, ammonia refrigeration unit and water cooling unit.
The features:
This refrigerate unit is cabinet shape, structure tight, good performance;
This refrigerate unit is semi. Closed compressor unit, small vibration,low noise, and credible in operation.
With cooper,aluminum heat transformer, big air transit area, high heat transfer rate and long life period.

Rainy weather today cool outdoor sports diesel generators at the time | diesel generators price / 2010-08-04
The rain is finally down. Since the summer, the activities of the western Pacific subtropical high have been different from those of the normal years. This has caused Beijing's rain in the main flood season from late July to early August to be significantly less so far. It is precisely this way that today's rainfall has reduced the past thunder and clamor, but it has progressed from west to east in a nearly even pace, and it is destined to the fate of today's rainfall.
The rain is not big, but it is still a good time. More than 10 points in the urban area, it is expected to continue until around night. If there is no rainfall, the temperature will almost always be in an ascending stage before 4 pm, and today's rainfall occurs precisely during the time when the temperature usually rises significantly. This will cause the temperature to stop rising and will follow the rainfall. It continued to decline slightly, so today's high temperature in the city is expected to be around 27°C and the weather will not heat up. At night, the main force of cold air gradually controls Beijing, and the rainfall weather is from small to small. Under the effect of cold air, the low temperature of tomorrow morning is expected to drop to 22°C and the weather is cool and comfortable. Fresh air tomorrow morning, the atmosphere is more translucent, the weather is cool, very suitable for outdoor morning exercises.
In the daytime, the weather will gradually turn from cloudy to clear. Light will help the temperature rise rapidly. However, the city is controlled by the air-conditioning regime and the temperature is not as high as it should be. The high temperature in the afternoon is expected to be about 32°C. The main thing is the small northerly wind. The air is much cleaner than today.
