Calorifer is a heat exchanger, with a specific of air (or other gas) preheat. Usually is directly in a Duct installed. Heat Exchanger usually is separate unit.

A calorifer is a type of radiator that heats a room by circulating hot water through its pipes. A heat exchanger is a device that transfers heat from one fluid to another without the fluids mixing, typically used in heating, cooling, or refrigeration systems. The key difference is that calorifers are specifically designed for room heating, while heat exchangers can be used for various heat transfer applications.
The efficiency of a heat exchanger is directly proportional to its surface area. This means that a larger surface area allows for more heat transfer, resulting in a more efficient heat exchanger.
A heat exchanger is a device that transfers heat between two mediums without mixing them, while an evaporator is a specific type of heat exchanger that facilitates the phase change of a liquid to a gas through the addition of heat. In other words, all evaporators are heat exchangers, but not all heat exchangers are evaporators.
A test ring in a heat exchanger is a device used during the manufacturing process to verify the integrity and quality of the welds. It typically consists of a metal ring that is welded onto the heat exchanger assembly and then tested for leaks or other defects using pressure or other testing methods. This helps ensure that the heat exchanger will perform effectively and safely once it is installed in its intended application.
Tube pitch refers to the center-to-center distance between adjacent tubes in a heat exchanger or a tube bundle. It plays a critical role in determining the heat transfer efficiency and pressure drop in the system. Optimal tube pitch is typically chosen based on factors such as fluid flow requirements and heat exchanger design constraints.
In refrigeration, delta t (ΔT) refers to the temperature difference between two points, typically the evaporator and condenser temperatures. It is an important factor in determining the efficiency and performance of a refrigeration system, with a larger delta t generally indicating better heat transfer and system effectiveness.
