What is a heat pump? A heat pump is a machine that by reversing its refrigeration cycle can provide heating instead of cooling. Because a heat pump uses a refrigerant it can upgrade the heat in air at even -15ºC to a usable heat source to heat buildings. Difficult to understand perhaps but imagine a domestic fridge or freezer‚ reverse its cycle and that black grille on the back will be very cold whilst inside will be very hot. Heat pumps can extract heat from air and water and are nearly always

in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine the heat transfer rate‚ the

indoor component is an evaporator and fan. The two sections are connected with a set of electrical wires and tubing used to transport air between the two sections. Indoor components Components | Functions | | Evaporator coil: It is where the heat exchange is done with the room. It consists of fins and tubes. | | Remote control: It is where user control the functions of the air conditioner. Displays at the panel may indicate the mode of operation‚ timer‚ on/off status‚ fan speed and other

Abstract Different substances react in various ways when exposed to heat. The amount of energy necessary to heat a certain amount of water by one degree is different than that of another liquid or substance. The technical term used to determine this characteristic is called heat capacity or specific heat capacity. The purpose of this experiment is to find the heat capacity of water‚ orange juice‚ and olive oil. A couple of very specific equipment is needed in order to complete this experiment

The Process of Paradoxical Heat Sensation Vy Tran West Covina High School Abstract The following research study examined the effects of using a warm stimulus cold stimulus instead of a hot stimulus and a cold stimulus to perform a sensation known as paradoxical heat. In the process of paradoxical heat sensation‚ a hot and cold stimulus is synchronically stimulated giving off a feeling we believe is very hot but is actually two stimuli activating together. The

Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece

Joule Heat John Doe 4/3/2014 Introduction The objective of this lab is to learn that whenever there is an electrical current in a conductor‚ there is some electrical energy that is converted into heat energy. The heat generated in an electrical circuit is commonly referred to as joule heat. Sir James Joule studies of these separate phenomena lead him to the discovery of the proportionality constant known as the Joule equivalent of heat‚ denoted by J. The Joule equivalent of heat is the amount
