Difference between Heat Pump and Refrigerator

-
A Heat Pump is similar to a Refrigerator. The main difference between the Heat Pump and a Refrigerator is that their operating temperatures.
A heat pump takes heat from a lower temperature at a source and rejecting heat to the high temperature, with the help of some energy input in the form of work. And a Refrigerator takes high temperature and rejecting heat at Low temperature. It means heat pumps are used for keeping things hot and A refrigerator used for keeping things cold.

Heat Pump : A heat pump is a device that takes heat from one source and moves it into another locations through electrical or mechanical means. Heat pumps moves thermal energy in the opposite direction of spontaneous heat transfer , by observing the heat from a cold space and releasing it to a warmer one.. A heat pump use external power to accomplish the work of transferring energy from the heat source to the heat sink.

Refrigerator : A refrigerator is a machine for keeping things cold. A refrigerator consists of a thermally insulated compartment and also a heat pump that transfer the heat from the inside of the body( fridge) to its external environment so that the inside of the fridge is cooled to a temperature bellow the room temperature.

Difference between Heat Pump and Refrigerator:

There are the following some differences between the Heat pump and Refrigerator.
1. Transfer of heat: The main purpose of the heat pump is to heat the room during winter seasons or when the atmospheric temperature is very low . it absorbs the heat from the atmosphere which is at low temperature and throws it to the room which is it at high temperature and which is to be heated. 
And the other side the Refrigerator main purpose is to chill or cold freeze substances, by maintaining very low temperature in the freezer. It absorbs the heat from the freezer or evaporator and throws it to the atmosphere which is at high temperature.

2. Location of the Evaporator: In the Heat Pump the evaporator is located outside of the room which is to be heated. The evaporator absorbs the heat, which is later thrown inside the room for heating.
In the refrigerator the evaporator is located in the freezer section. The evaporator absorbs the heat from the substance, which is to be cooled.

3. Location of the Condenser: In the heat pump the condenser is located inside the room and it acts as the heating device.
In the refrigerator the condenser is located outside of the refrigerator and it is exposed to the atmosphere. It is through the condenser that the heat is thrown to the atmosphere. 

4. Working of Evaporator and Condenser: In the heat pump , it is the condenser that perform the main function of heating the room, while the evaporator performs the function of absorbing the heat from the atmosphere.
In the Refrigerator the evaporator performs the main function of chilling or freezing, while the condenser performs the function of delivering the heat to the atmosphere.

Two Stroke Petrol Engine

   Two Stroke Petrol Engine Two Stroke engine is a type internal combustion engine, which completes a power cycle in 'up and down' moments,it means two stroke of the piston during only one crankshaft revolution.  This is in contrast to a four stroke engine, which required four stroke of the piston to completed a power cycle during two crankshaft revolution.  In a two stroke engine the end of the combustion stroke and the begging of the compression stroke happen at together with the intake and exhaust function occurring at the same time. Two stroke petrol engine are used when mechanical simplicity, light weight , and high power to weight ratio and design priorities, with the traditional lubrication technique of mixing oil into the fuel. They are also have an advantage of working in an any orientation , as there is no oil reservoir dependent on gravity, this is an essential property for hand held tool such as chainsaws. Theoretically the power outpu...

Heat Pump A heat pump is a device that takes heat from one source and moves it to another location through electrical or mechanical means. In other word- A device that transfers heat from a colder area to a hotter area by using mechanical energy, as in a refrigerator. Heat pumps moves thermal energy in the opposite direction of spontaneous heat transfer, by observing the heat from a clod space and releasing it to a warmer one. A heat pump uses external power to accomplish the work of transferring energy from the heat source to the heat sink. A Condenser, an Expansion valve ,an Evaporator and a compressor are the main part of the heat pump. The heat transfer medium circulated through these components is called refrigerant. Lord Kelvin describes the theory of underlying heat pump in 1852. The First heat pump was developed by the Peter von Rittinger in 1855-1857. Working of Heat Pump  Heat pump transfer heat by circulating a substance called a refrigerant through a cyc...

Wind Turbine A Wind Turbine is a device which converts the kinetic energy of wind into electricity. Wind turbine are manufactured in a wide range of vertical and horizontal axis. Small turbine are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic signals. Large turbine can use for making contribution of a domestic power supply. Wind turbine work on a simple principle, instead of using electricity to make wind like a fan-wind turbine use wind to make electricity. Wind turns the propeller like blades of a turbine around a rotor, which spin a generator, which creates the electricity. The first known practical wind power plant were built in Sistan , an eastern province of Persia from the 7th century. these Panemone were vertical wind mill, which have long vertical drive shaft with rectangular blades, it makes six to twelve sails covered in reed matting or cloth material, these wind mill were used to grand grain or draw up wa...
