Part 3 of “A Guide to Commercial HVAC Systems” shines a light on common commercial HVAC challenges. Learn about their causes, how to identify them early, and the steps to prevent or address these issues effectively. Knowledge is power! https://buff.ly/3QeiSKe

Planning for Successful VRF/VRV Installation.What steps are included in a typical installation workflow of VRV/VRF?1) Mounting indoor unit/fan coil.2) Assemble and connect refrigeration piping.3) Installing Y branch copper fittings also known as refnets or/and branch boxes for heat recovery systems.4) Providing drainage.Only qualified personnel should install and service the equipment.The installation, starting up, and servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

🔌Within the field of enclosure, the use of electromechanical limit switches plays a crucial role. These devices are designed for circuit isolation, ensuring operator safety during inspections, maintenance, or expansions of electrical cabinets. ⚠️But how many types of limit switches are there? And what types of applications are they best suited for?

Friday’s Find – Things are starting to heat up! 🥵Whilst recently out on-site, one of our observatory inspectors came across thermal damage whilst conducting testing in a control panel for a large industrial 63 AMP Three Phase Oven. The Yellow/L2 phase supply conductor to this panel, was originally hidden behind a clear, Perspex protective casing, which was going into the supply side of the main rotary isolator.Resultantly, this hid most of the damage, only showing a slight bit of charring on the cable. Fortunately, due to the thorough work of Aaron Johnson, on closer inspection once the Perspex cover was removed, the cable itself was not terminated correctly into the terminal. As a result of this, over time this caused heat build-up and potential arcing within the terminal, which ultimately led to the thermal damage and a C1 observation to be identified.This was immediately brought to the client’s attention and was rectified including a further test, which left them even happier with the panel.👀Would this have been spotted in your routine inspection and testing?

Depending on the type of trap, steam traps can be installed vertically. In fact, installing traps vertically can be more effective for certain applications or locations than installing them horizontally.In the case of a Free Float® steam trap, installation orientation is crucial to steam trap performance and installation just a few degrees in excess of the recommended tolerance could cause steam to leak. While a JX series Free Float® steam trap is limited to horizontal orientation, the SS1 Free Float® trap, designed for main lines, and the FJ32-X QuickTrap® are available in a vertical configuration, saving valuable space by removing the need for horizontal piping.Other types of traps may be less restricted by the orientation, such as temperature control traps or disc type traps, however, performance may be reduced if not installed in the recommended orientation. Always consult the manual before installing a steam trap.Contact TLV’s steam specialists for more information on steam traps for vertical installation.

Incorrect chiller and heat pump installation can cause unit malfunction. The more common is incorrect crane lifting, where the lifting straps on the sides of the unit or base supports are not level or not present. Incorrect lifting can cause leaks due to unequal force applied to the unit or cause misalignment on panel doors or condenser coils. Another issue regards the location where the units are to be installed, often there is improper air re-circulation which causes energy efficiency reduction or faults on peak hot/cold days. This can happen because the installer does not understand that the minimum clearance indicated is for service purposes, not for ventilation, therefore does not consider the space needed for ventilation.

👍🔧🇬🇧😁Great day spent in Hull, I was fortunate to spend sometime on site. always great to put our tools through there paces! customer could quickly see the benefits of using the Rp50 DigitalWhen building new pipelines and after repairs to existing systems, leak testing is essential. Because only leak-proof pipelines are safe pipelines. And that is important in case damage does occur. Better safe than sorry.Until now, there were basically two options: uncomplicated testing, but time-consuming documentation by hand, or testing with highly sensitive and cost-intensive digital pressure testing equipment and creating a digital test report.Now, for the first time, there is the perfect combination of both for testing water-bearing pipes!With the RP 50 Digital, HVAC professionals have the advantages of the simple handling and robustness of a normal test pump plus the advantages of digital documentation at their fingertips. Simply convenient.👍🔧🇬🇧😁ROTHENBERGER UK 🇬🇧ROTHENBERGER Werkzeuge GmbH 🇩🇪

When installing the cassation ventilation fans, the sizes of the intake pipes to the outside must be taken into account for the success of the ventilation system and the maintenance of ventilation efficiency in the vacuum as follows:👇🏼Fan size 41cfm to 109cfm (4 inch pipe installation) Fan size 182cfm to 344cfm (6 inch pipe installation)
