Refrigeration theory law

WebEquation 1. dT/dt = – k (T-Ts) Since the above equation is a Separable differential equation, with the help of this equation and solving it more, we can get a general solution, i.e. we can get the Temperature Tα or the Rate of Cooling dT/dt as per our requirement. Now let’s divide both sides by (T-Ts) and multiply by dt. WebNov 1, 2024 · Introduction: Refrigeration is the process of transferring energy from a low energy domain to a high energy domain. According to the second law of thermodynamics, heat cannot be transferred from a cold location to a hotter one unless work is introduced to the process. The devices that apply this process are called refrigerators.

The term refrigeration denotes cooling of a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature). Refrigeration is considered an artificial, or human-made, cooling method. Refrigeration refers to the process by which energy, in the form of heat, is rem… WebMay 29, 2024 · The Refrigeration basic principle is that with the aid of a heat pump, the refrigerant is being compressed to the condenser and capillary tube thus increasing its temperature (50-60°C) and pressure (750 kPa)in the refrigerator being cooled down by the condensing unit to 32°C depending the existing ambient temperature.
