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.

What is difference between heatexchanger and evaporator?
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.
What is test ring in Heat exchanger?
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.
What is tube pitch?
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.
What is delta t in refrigeration?
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.
What is the difference between indirect and direct hot water cylinders?
Direct hot water cylinders are heated directly by an immersion heater within the cylinder, whereas indirect hot water cylinders are heated indirectly by a boiler or other external heat source through a coil or heat exchanger within the cylinder. Indirect cylinders are more efficient as they can be connected to renewable energy sources like solar panels or heat pumps.
What is the differences between an oil cooler and a heat exchanger on an airplane?
difference between cooler and heat exchangers
Difference between heat exchanger and condenser?
A heat exchanger is a device used to transfer heat between two fluids at different temperatures. It can be used for both heating and cooling applications. A condenser is a specific type of heat exchanger that is designed to transfer heat from a vapor to a liquid state, typically used in refrigeration and air conditioning systems.
Difference between heat rejection and heat absoarb in refrigerator?
Heat is absorbed by the refrigerant liquid inside the fridge, and rejected by the heat exchanger on the back of it.
Heat exchanger for ammonia absorption refrigeration system?
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
What is difference between condenser and heat exchanger?
A condenser is a specific type of heat exchanger that is used to transfer heat and convert a vapor or gas into its liquid form by removing heat. A heat exchanger, on the other hand, refers to a device that transfers heat between two fluids without them coming into direct contact. While a condenser serves the purpose of condensing a vapor into a liquid, a heat exchanger can be used for various purposes such as heating, cooling, or heat recovery.
What is the difference between double pipe heat exchanger and shell and tube heat exchanger?
double pipe heat exchanger is made if two concentric tubes one carrying cold flow and the other one carrying hot flow. but shell and tube hear exchangers are made of a shell like a vessel filled with many thin tubes to transfer heat between fluids. there are more data available at : http://scopewe.com/double-pipe-heat-exchanger-design-part-1/
Why you we use log mean temperature difference formula?
The use of the LMTD arises straightforwardly from the analysis of a heat exchanger with constant flow rate and fluid thermal properties. It is a simple method to approximated the temperature diving force in a heat exchanger. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. The larger the LMTD, the more heat is transferred.
Are spacers necessary in heat exchanger?
because it maintain space between baffels

Capacity ratio of a heat exchanger?
The capacity ratio of a heat exchanger is the ratio of the actual heat transfer rate to the maximum possible heat transfer rate. It indicates the effectiveness of the heat exchanger in transferring heat between the hot and cold fluids. A higher capacity ratio signifies better performance of the heat exchanger in transferring heat.
What is heat exchanger duty?
The duty of a heat exchanger can be defined in an easy way as "The amount of heat exchanged from a fluid at a higher temperature to the fluid at lower temperature in unit time by a heat exchanger is called its duty"
