In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor. This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
Liebherr is a German-Swiss multinational equipment manufacturer based in Bulle, Switzerland, with its main production facilities and origins in Germany.. Liebherr consists of over 130 companies organized into 11 divisions: earthmoving, mining, mobile cranes, tower cranes, concrete technology, maritime cranes, aerospace and transportation systems, machine tools and automation systems, domestic ...
Direct cool is one of the two major types of techniques used in domestic refrigerators, the other being the "frost-free" type. Direct-cool refrigerators produce the cooling effect by a natural convection process from cooled surfaces in the insulated compartment that is being cooled. Water vapor that contacts the cooled surface freezes.
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
Haier was founded as Qingdao Refrigerator Co. in 1984. With China opening up to world markets, foreign corporations began searching for partnerships in China. One of these, Germany's refrigerator company Liebherr, entered into a joint-venture contract with Qingdao Refrigerator Co., offering technology and equipment to its Chinese counterpart.
The Mitsubishi model was the first air conditioner with a cross-flow fan. [64] [65] [66] In 1969, the first mini-split air conditioner was sold in the US. [67] Multi-zone ductless systems were invented by Daikin in 1973, and variable refrigerant flow systems (which can be thought of as larger multi-split systems) were also invented by Daikin in ...
