Replacing a Compressor – Aircon system is not cooling properly

By |2019-03-20T13:34:00+02:00March 20th, 2019|Air Conditioning, Articles, Products|

This week we will be discussing the issue of an air-conditioning system not cooling properly. The louver temperature should be about 30-40 deg F cooler than ambient temperature. The Air-conditioning system we are working on, is a GM Clutch Cycling Orifice Tube system (CCOT). Please remember that you are about to start working on the [...]

10 avoidable Faults in Leak Testing

By |2018-12-03T11:26:55+02:00December 3rd, 2018|Air Conditioning, Latest news & Press releases, Products, Refrigeration Equipment|

Checking refrigeration, air conditioning and heating systems for leaks is a complex challenge. For example, even the wrong choice of leak test method, such as the water bath method, can cause the tester to overlook leaks because he has not considered the deformability and volume change of the test piece. Inficon has compiled a top 10 checklist of [...]

Chemical Refrigerants vs. Natural Refrigerants – what is the difference?

By |2018-09-19T08:15:25+02:00September 19th, 2018|Articles, Latest news & Press releases|

By Professor Dick Powell of Refrigerant Solutions. In both technical and non-technical literature, fluorine-containing (HFC) refrigerants are increasingly referred to as ‘chemical’ or ‘synthetic’ refrigerants in contrast to the so-called ‘natural’ refrigerants. Generally ‘chemical’ is now seen by some as being ‘bad’ and is contrasted with ‘natural’, which implies ‘good’. What’s the difference between chemical [...]

Compressor Failures: No compressor overload

By |2018-09-19T08:15:47+02:00August 28th, 2018|Articles, Products, Refrigeration Equipment|

One of the most common and simplest of causes of compressors failure is due to the plant electrics not having a compressor overload fitted. When large Semi-Hermetic or Hermetic Compressors are fitted to systems where the compressor contactor has no overload fitted, the compressor is left wide open to liquid washout, Valve breakages or even [...]

Adjusting Oxy-Acetylene Flames

In the last issue we looked at Safety when Brazing. This month, we move onto Adjusting Oxy-Acetylene Flames. NOTE: Adhere to and apply all Safety Precautions! Lighting the Torch Connect the welding equipment and purge all the impure gas. Set the working pressure for the work to be welded. Point the blowpipe (torch) away from any persons [...]

Compressor Failures: Lack of Lubrication

By |2018-08-17T10:00:13+02:00August 15th, 2018|Articles, Products, Refrigeration Equipment|

Lack of lubrication can be categorised under two main headings. They are: Lack of lubrication Lack of oil Lack of lubrication: Lack of lubrication is where the oil either cannot lubricate the bearings due to the oil being degraded, or when the lubricant cannot reach the bearings due to blockages or loss of oil. Oil [...]

Compressor Failures: Overheating

By |2018-09-19T08:16:06+02:00August 2nd, 2018|Articles, Products, Refrigeration Equipment|

Compressors naturally run warm due to the heat from the Motor, from friction and from the Compression cycle. Providing the compressor runs within its design limits then it will give long and reliable service. When the compressor is run outside of its design limits or some other external situation exists that creates this problem then [...]

Compressor Failures: Liquid Slugging

By |2018-09-19T08:16:16+02:00July 27th, 2018|Articles, Products, Refrigeration Equipment|

Liquid Slugging is where extreme cases of Flooded Start or Liquid Flood Back occur. When large quantities of liquid refrigerant enter the compressor and then mix with the lubricating oil in the compressors sump. The resulting liquid/oil mixing and diluting, then creates major amounts of liquid and oil droplets in a frothy foam mixture. [...]

Various Pipe-Joining Methods

By |2018-08-17T09:52:41+02:00July 18th, 2018|Articles, Latest news & Press releases|

In this month's blog post, we share how to join pipes by means of the recognised oxyacetylene, silver soldering and copper joining methods - competently to specifications given in this element, applicable to domestic / small plant refrigeration systems. Safety Precautions Safety is very important. Carelessness can cause accidents, so it is necessary that [...]

Compressor Failures: Flooded Starts

By |2018-08-17T09:49:18+02:00July 12th, 2018|Articles, Products, Refrigeration Equipment|

Flooded starts are probably the major cause of compressor failures. Flooded starts occur when liquid refrigerant has migrated from the system and condensed into the compressor oil. Migration can occur in all systems up to a point, due to the vapour pressure of the refrigerant being greater than the vapour pressure of the oil. It [...]
