Direct Exchange Geothermal
Direct exchange geothermal heat pump The Direct exchange geothermal heat pump is the oldest type of geothermal heat pump technology. It is also the simplest and easiest to understand. The ground-coupling is achieved through a single loop circulating refrigerant in direct thermal contact with the ground (as opposed to a combination of a refrigerant loop and a water loop). The refrigerant leaves the heat pump appliance cabinet, circulates through a loop of copper tube buried underground, and exchanges heat with…...

Crank and Connecting Rod Introduction- The motion of assemblies is determined by the configuration of links and joints. Using the configurations the operation of rotational and sliding joints are examined and observed. This kind of mechanism is very commonplace in machines. Machines are made up of a number of parts and relative motion between the various parts permits the working of the machine. As the crank is rotated the rod starts moving but the velocity is not uniform. It is…...

Basic Principles and Benefits of Ssbsc
Before investigating the various ways of creating a SSBSC signal it would be prudent to understand the basic principal of such systems and their advantages. SSBSC technology has developed so as to over come some of the inefficiencies of DSBSC (Double Sideband Suppressed Carrier) technology. In both systems the signal information is carried in the side bands of the carrier frequency. However DSBSC transmits both sidebands and the suppressed carrier even though signal information from one sideband would be sufficient.…...

Impulse And Momentum Lab
Background: Momentum is a measure of inertia and can be defined by “mass in motion” ( Stan brought ,) anything with mass that is moving has momentum. Mo momentum can be calculated with p=mass x velocity, there fore momentum is dependent on both mass and velocity. Momentum is similar to energy in that both are always conserved, but energy ha s multiple forms and has to be in the right situation to be conserved. M momentum transferred is the integral…...

An object hat moves at a constant speed and changes direction is also experiencing acceleration even though its speed never changes. Both the acceleration produced by changing speed and the acceleration produced by changing direction require a net force.

Effect Of Air Conditioner On Global Warming
Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location, transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat, and this additional heat must also be exhausted. Thus, air conditioning results in net heat release to the environment. The warming effect is aggravated, moreover, because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this electricity…...
