Plate heat exchanger calculation method. To solve a thermal problem, we need to know several parameters. Further data can then be determined. The six most important parameters include: The amount of heat to be transferred (heat load) The inlet.
Adiabatic technology with zero moisture leakage Alfa Laval Abatigo prevents any water drift to the heat exchangers, keeping them completely dry – preventing scaling, corrosion, and dangerous waterborne diseases such as Legionella. The cooler is designed to usually work in dry mode, when the adiabatic mode is activated, it works as follows:. High-temperature ambient air passes through lower adiabatic chamber. Inside this chamber, nozzles spray the coil with a fine mist of water from a separate source. The air is cooled due to humidification, prior to contact with heat exchangers. The chamber’s design prevents any water drift outside the chamber when the cooled air travels to the heat exchanger. Digital control system continuously adjusts the amount of water sprayed to ensure consistent cooling.

The Air Conditioning, Heating and Refrigeration Institute (AHRI) Standard 400 certification is an independent, third-party verification of thermal performance. Through its certification program and standards, AHRI strives to help customers save energy, improve their productivity and help to ensure a better environment. AHRI Certified™ is the trusted mark of performance assurance for heating, ventilation, air conditioning and commercial refrigeration equipment. Products earning the mark undergo rigorous, independent annual evaluation to ensure that they perform according to the manufacturers’ published claims. Certifying HVACR equipment and component performance allows consumers to compare products based on independently verified performance ratings.
To find AHRI Certified™ products, go to the. AHRI Certification Procedures and Benefits To certify a product to AHRI standards, the manufacturer submits specifications and performance data to AHRI for performance evaluation and potential certification.
Once certified, buyers and users can be assured that:. The plate heat exchanger will perform in accordance with the manufacturer’s published ratings. Product performance can be easily compared for their specific application. The CBAQ range of brazed plate heat exchangers has numerous advantages over traditional heat exchangers HVAC installations. The exceptional heat transfer efficiency makes all CBAQ units very compact. As a result, they can tackle large-capacity duties even though there is only limited installation space available. The brazed construction also does away with gaskets, making CBAQ units ideal in applications where temperatures and/or pressures are high.
Examples include district heating and a wide range of heating, cooling and tap water solutions. Units in the CBAQ range are available in many different sizes and capacities. The Air-Conditioning, Heating, and Refrigeration Institute Product Performance Certification Programme is a voluntary programme, administered and governed by AHRI, which ensures that various types of heating, ventilation, air conditioning, refrigeration, and water heating products perform according to manufacturers’ published claims. Products that are certified through the AHRI Product Performance Certification Programme are continuously tested, at the direction of AHRI, by an independent third-party laboratory, contracted by AHRI, to determine the product’s ability to conform to one or more product rating standards or specifications. Heat transfer technology involves bringing two substances at different temperatures close to each other so that one either heats or cools the other. Design A brazed plate heat exchanger consists of thin, corrugated stainless steel plates, stacked into a plate package and brazed together with pure copper.
The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. The plate design guarantees the longest possible life. Brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates.
Pressure peaks and rapid temperature cause substantial physical stresses within the materials, and Alfa Laval’s research has focused on the details of these phenomena in order to ensure designs that are extremely resilient and provide a long service life. Working principle Channels for the fluids are formed between the plates. The two fluids flow in alternate channels in a counter-current flow pattern in order to achieve the most efficient heat transfer. The transfer of heat energy from one fluid to the other takes place over the large surface. The corrugation of the plates is specially designed to induce maximum turbulence and even distribution of both the fluid flows in order to make heat transfer as efficient as possible.
Material The plates and connections are made of stainless steel. The brazing material is made of pure copper. Cleaning The turbulent flow in the heat exchanger has a self-cleaning effect.
