Basic Thermodynamics For Refrigeration and Air Conditioning – Part 1 // W.9.1

Thermodynamics, White Paper /

Introduction Thermodynamics, as with most concepts in science and physics, is most accurately described using mathematical equations. However, simple explanations, although not perfectly accurate, are sufficient to convey the information needed to understand everyday experiences. This paper is an attempt to simplify these concepts. Thermodynamics simply describes the movement of heat. Thermodynamics is derived from thermo, meaning heat, and dynamics, (literally “power”),

Understanding Ethernet Communication – Protocols // W.5.4

Ethernet, White Paper /

Protocols All of us are familiar with protocols for human communication, society’s rules about appearance, speaking, listening and understanding. These rules govern different layers of communication. They work to help us successfully communicate. Similarly, in the computer world, a protocol is a set of rules that governs communications between the computers on a network. So,

Understanding Ethernet Communication – Networks // W.5.1

Ethernet - Networks, White Paper /

Networks The underlying structure of communications is a network.  A network consists of two or more computers that are linked together to provide shared access to file servers, printers, or to electronic communications. The computers can be linked through phone lines, cables, satellite, radio waves or infrared light beams. There are two basic types of

Frost and Defrost: How it happens and why it is needed // W.1.1

Frost and Defrost, White Paper /

Refrigeration is used to assure proper storage temperature of food products.  This is most often accomplished by using the vapor compression cycle.  In this technique, refrigerant vapor is compressed by a compressor, condensed into a liquid in a con-denser by the rejection of heat, expanded by a restrictive device, and fed into an evaporator where
