Alfa Laval Heat Exchanger. Gasketed plate heat exchangers (PHE) meets almost all of heat transfer requirements. They are highly flexible with a wide range of models. Connection sizes range from 1″ to 16″. Plate materials are available in a wide variety such as stainless steel 316, 304 and titanium. Plate Heat Exchangers. Plate Heat Exchanger (PHE) is one of established types of enhanced HEs. To estimate possible benefits of that kind of heat transfer enhancement, a mathematical model of PHE, which accounts for different plate types and corresponding corrugations geometry, is used. The Alfa Laval Cold Room Calculator turned out to be a very easy-to-use tool with thousands of satisfied users all over the world. The functionality is fully based on the Alfa Laval heat exchanger selection software. 2003, English, Book, Illustrated edition: Data structures using Java / Yedidyah Langsam, Moshe J.

Mobile App for iOS & Android Rules of thumb or accuracy? For making cold room calculations refrigeration installers can rely on experience based and widely used ‘rules of thumb’: 15-20 watt/m 3 for a large frozen storage room, 60-70 watt/m 3 for a fresh fruit cooling room, etc. Convenient, quick, but not very accurate. A more accurate method is a detailed cold room calculation using refined calculation formulas in combination with product data tables. This can be done manually or using commercial cold room calculation software. This is relatively time consuming, a computer is required and in addition the software is not for free. And if for instance the room door remains open a little longer than planned, so much for calculation accuracy Quick & easy To offer the market an convenient intermediate solution, Alfa Laval offers a quick & easy cold room calculation module in the selection software for Alfa Laval heat exchangers. This non-academic software enabled customers to make quick and reliable ‘stand alone’ calculations for a cold/freezing rooms. Alfa Laval Plate And Frame Heat Exchanger![]() Mobile App – for free! With mobile technology rapidly developing, Alfa Laval decided to translate the existing cold room calculation software into a mobile App for smartphones and tablets. This App is available for free in both Apple & Google app stores. The Alfa Laval Cold Room Calculator turned out to be a very easy-to-use tool with thousands of satisfied users all over the world. The functionality is fully based on the Alfa Laval heat exchanger selection software. ![]() The App quickly calculates a reliable cooling capacity for any cold or freezing room. Alfa Laval Plate Heat Exchanger Calculation Software![]() ![]() Alfa Laval Heat Exchanger PricesPlate 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 and outlet temperatures on the primary and secondary sides • The maximum allowable pressure drop on the primary and secondary sides • The maximum operating temperature • The maximum operating pressure • The flowrate on the primary and secondary sides If the flow rate, specific heat and temperature difference on one side are known, the heat load can be calculated. Calculation method The heat load of a heat exchanger can be derived from the following two formulas: 1. Heat load, Theta and LMTD calculation Where: P = heat load (btu/h) m = mass flow rate (lb/h) c p = specific heat (btu/lb °F) δt = temperature difference between inlet and outlet on one side (°F) k = heat transfer coefficient (btu/ft 2 h °F) A = heat transfer area (ft 2) LMTD = log mean temperature difference T1 = Inlet temperature - hot side T2 = Outlet temperature - hot side T3 = Inlet temperature - cold side T4 = Outlet temperature - cold side LMTD can be calculated by using the following formula, where ∆T1 = T1–T4 and ∆T2 = T2–T3 2.
