The guide compares different Air Handling Unit types for HVAC systems. It explores key factors for AHU selection, including building characteristics, occupancy patterns, and energy efficiency. The article discusses various AHU types such as Constant Volume, Variable Air Volume, Dual Duct, Multizone, and Single Zone units. It emphasizes the importance of balancing initial costs with long-term savings and considering maintenance requirements when choosing an AHU. https://lnkd.in/d_ckfYDz

Air-cooled chillers require regular maintenance for optimal performance and longevity. Daily tasks include visual inspections, checking for unusual noises, monitoring refrigerant levels, and examining electrical connections. Monthly and quarterly maintenance involves testing safety controls, checking oil levels, analyzing compressor performance, inspecting belts and pulleys, and maintaining air filters. Proper maintenance reduces breakdowns, improves efficiency, and extends equipment lifespan. https://lnkd.in/dWWaqDYF

The article compares air-cooled and water-cooled chillers for HVAC systems. It details the operating principles, advantages, and limitations of each type. Air-cooled chillers are simpler and more cost-effective for smaller applications, while water-cooled chillers offer higher efficiency and performance for large-scale projects. The selection depends on factors like costs, efficiency, space constraints, environmental conditions, and maintenance requirements. https://lnkd.in/dBg_kq6k

Log P-H Diagram Refrigeration https://lnkd.in/dRKFFFKm The thermodynamic processes in the refrigeration cycle are complex. Calculation using formulae and tables requires a considerable amount of effort due to the three different states of the refrigerant from liquid, boiling and gaseous. Therefore, for reasons of simplify cation, the log p-h diagram was introduced.

Carrier HAP Training Tutorials https://lnkd.in/d5dWSqmU Series of training videos and articles are designed to help users get-started and with fundamental tasks such as installation, setting preferences, utilizing the HAP building wizards and more

Refrigerant Property Diagrams https://lnkd.in/df4-sb-r The idea of using a refrigerant diagram is that it makes it possible to represent the processes in the refrigeration system in such a way that analysis and evaluation of the process becomes easy.

Direct Return Piping Systems https://lnkd.in/dfixqkt5 Closed-loop systems can be further classified as direct return or reverse return. The direct return system allows piping to be run in the most direct path to optimize piping costs. The reverse return system is piped so that the length of the water circuit through the supply and return piping to each fan coil or air handler is essentially the same.

Types of Water Distribution Systems https://lnkd.in/d-N88EdZ There are four main types of water distribution systems. They are defined by the number of pipes used in the system – 1-pipe, 2-pipe, 3-pipe, and 4-pipe. While this article will discuss primarily chilled water and condenser water system piping system design, it is important to understand the evolution from 1-pipe into the other three systems, all of which are used for heating as well as cooling.

Types of Piping Systems https://lnkd.in/erMR9ZRQ Understanding of the three basic types of piping systems: closed-loop, open-loop, and once-thru. Closed-Loop (Evaporator), Open-Loop (Condenser), Once-Thru.
