DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

A simple stylized diagram of the refrigeration cycle: 1) condensing coil, 2) expansion valve, 3) evaporator coil, 4) compressor. Cooling in traditional air conditioner systems is accomplished using the vapor-compression cycle, which uses a refrigerant's forced circulation and phase change between gas and liquid to transfer heat.
Coca-Cola has fielded CO 2-based beverage coolers and the U.S. Army is considering CO 2 refrigeration. [64] [65] Due to the need to operate at pressures of up to 130 bars (1,900 psi; 13,000 kPa), CO 2 systems require highly resistant components, however these have already been developed for mass production in many sectors.
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]
The system normally has eight main components: a compressor, a reservoir, a reversing valve which selects between heating and cooling mode, two thermal expansion valves (one used when in heating mode and the other when used in cooling mode) and two heat exchangers, one associated with the external heat source/sink and the other with the ...
Limescale may foul the system over time and require periodic acid cleaning. This is much more of a problem with cooling systems than heating systems. [17] A standing column well system is a specialized type of open-loop system where water is drawn from the bottom of a deep rock well, passed through a heat pump, and returned to the top of the ...
At Tuesday's meeting, the Lincoln County Commission heard testimony for over two hours on whether they should approve a new 1,000 cattle confinement operation southwest of Canton, and just a mile ...
