Fin–tube coils, which typically combine aluminum fins with copper tubes, are widely used in air-conditioning and HVAC systems. Corrosion in these components leads to reduced heat-transfer performance, efficiency loss, leakage, and shortened service life. The following sections present practical, preventive engineering methods for protecting these coils.
There are various types of fin tubes available for heat transfer applications, each uniquely designed with specific dependencies. Each type of fin tube has its advantages and disadvantages in specific applications to be used in the most suitable conditions. Different Types of Fin Tubes Based on Type of Fin Fin Plate Wrap-on Fin Extruded Fin Fin Plates The plate heat exchanger is a type of heat exchanger that uses plates to transfer heat between fluids. In most cases, the plate fin is categorized as a compact...
Definition of Subcooling Subcooling refers to a liquid whose temperature is lower than its saturation point. Process of Subcooling Subcooling and condensation occur in the condenser. The use of subcooling is for transferring refrigerant from the condenser to the thermostatic expansion valve in liquid form. Mechanism of Refrigeration Systems The refrigerant absorbs heat and releases it to the environment after leaving the compressor and reaching the condenser. The temperature decreases in the condenser, and the refrigerant transitions to the liquid phase. Advantages of Subcooling Increased...
1. Introduction A brief introduction about the impact of system changes on coil performance and the importance of adjusting operational conditions. 2. System Changes Affecting the Inefficiency of Coils • The impact of temperature and fluid and air volume on coil performance. • The following aspects are specifically mentioned: • Fluid Temperature: o If the temperature is higher or lower than the specified amount, the coil’s performance is disrupted. • Air Temperature: o Similarly, if the incoming air temperature is not suitable, it negatively affects
Fin tube coils are present in many process heating systems and are typically the first components to show signs of improper filtration upstream. In environments where contamination is an issue, these coils can lead to significant problems, including pump failures, compressor issues, and fan malfunctions. These coils, also known as heat exchange coils, consist of two main parts for heat transfer: the first part is the tubes, referred to as the primary surface, and the second part is...

Differences in Thermal Comfort Between Men and Women 1. Introduction Indoor air conditioning is based on experimental models of thermal comfort developed in the 1960s. 2. Metabolism and Standards • Standard values for one of the fundamental variables, the metabolic rate (the amount of energy expenditure and heat production of each individual), are determined based on the metabolism of an average man. • This value is 35% higher than the predicted basal metabolic rate of an average woman. 3. Women's Metabolic Rate • According to recent findings,...
Thermal Comfort in Modern Architecture Thermal comfort has become one of the important and controversial topics in today's architecture.
