Easy Finding Fault Location for HVAC Trouble Shooting: Danfoss Guide

HVAC fault finding and troubleshooting within a minimal time denote an HVAC technician's efficiency. 

Especially find fault location troubleshooting during system breakdown is very challenging for an HVAC technician.

Hope this troubleshooting fault location guide will be helpful for any beginner as well as the experienced technician.

Actually, fault finding and troubleshooting have no specific rules that can follow to find the fault location mathematically, performance depends on the technician's skilled experience to find the fault location and troubleshooting in short.

This guide will discuss some common faults in refrigeration systems, causes of maximum faults, and ways to easily find out the faulty parts and system of remedy.

However, this guide will buildup a technician to find which types of fault and where occurs the fault in the refrigeration system. 

This guide no more deals with the electronic control system and the troubleshooting, it will discuss in another article.

How to Find Faulty Parts Easily In Refrigeration System?

There are two main faults in may find in a refrigeration system- visible and non-visible.

The visible fault may find with necked eyes, but detect non-visible faults it’s needs tools or equipment help.

Visible or recognizable faults can be seen like-air cooled condensers, water-cooled condensers, receivers with sight glass, receiver stop valves, liquid lines, filter drier, sight glass, thermostatic expansion valves, air coolers, liquid coolers, suction lines, the regulator in the suction line, compressor & cooled room, etc.;

Faults can be felt, like- solenoid valves & filter drier, etc;

Faults can be heard, like- regulator in the suction line & compressor, etc.;

Fault can be smelled, like- a cooled room, etc.

Fault-finding tools are required to find some faults, like refrigeration leakage, temperature deviation, etc.

Danfoss HVAC System History

Danfoss is a global manufacturer of HVAC (Heating, Ventilation, and Air Conditioning) systems and a wide range of other products in the field of energy efficiency and climate solutions. The company was founded in 1933 by Mads Clausen in Nordborg, Denmark. Over the years, Danfoss has played a significant role in shaping the HVAC industry with its innovative technologies and solutions. Here is a brief overview of the history of Danfoss in the HVAC system sector:

1930s-1940s: Danfoss was established in 1933 and initially focused on manufacturing radiator thermostats. These early products were designed to regulate heating systems and save energy by maintaining a constant room temperature.

1950s-1960s: Danfoss introduced its first expansion valve for refrigeration systems in the 1950s, which marked the company's entry into the refrigeration and air conditioning market. Expansion valves are critical components that regulate the flow of refrigerant in cooling systems.

1970s-1980s: Danfoss continued to develop and innovate in the HVAC sector. In the 1970s, the company introduced variable speed drives (VSDs) for controlling the speed of electric motors in HVAC systems. This technology allowed for more precise control of airflows and energy consumption in HVAC applications.

1990s-2000s: Danfoss expanded its product range to include electronic controls, sensors, and other components for various HVAC applications. The company focused on improving energy efficiency and sustainability in HVAC systems, aligning with global efforts to reduce carbon emissions.

2010s-Present: In recent years, Danfoss has continued to advance its HVAC technologies with a strong emphasis on smart and connected solutions. The company has developed products and systems that utilize IoT (Internet of Things) technology to optimize energy consumption, enhance system performance, and provide remote monitoring and control capabilities.

Danfoss's HVAC systems history is characterized by a commitment to innovation, energy efficiency, and environmental sustainability. The company's products have contributed to improving the performance and energy efficiency of HVAC systems in various residential, commercial, and industrial settings.

Please note that the information provided here is based on the knowledge available up until September 2021, and there may have been further developments in Danfoss's history since that time.
