Thermally Driven Air Conditioning System: An Up and Coming HVAC Technology

What is the newest advancement in air conditioning?

The most recent and emerging advancement in air conditioning that is focused on the viable development drive is thermally determined forced air systems. The forced air systems are an excellent alternative to the conventional cooling system and are energy efficient.

Modern cooling systems produce refrigeration and then cool the air using highly effective electrically controlled blowers. Although extremely effective, these systems use expensive energy, particularly during the busy summer months when demand is highest.

Solar Improved Systems

In comparison to electrically determined cooling, the use of thermally determined chillers is less expensive. These chillers can be powered by solar energy and strengthened with small amounts of propane gas. The most effective of these systems makes use of double impact chillers, but it also needs high temperatures (about 350 degrees Fahrenheit) as a driving temperature.

Module Thermoelectric (TEM)

Heat Pump

Two distinct materials make up a thermoelectric module, or TEM, which produces energy when subjected to temperature changes. Electrons migrate over a barrier between the two sides of the device when one side is subjected to a higher temperature than the other.

The heated side gets hotter than the cold side during a cooling cycle, and during a heating cycle, the opposite happens. This kind of technology requires less upkeep and maintains a high level of efficiency even in harsh environments. The TEM will continue to create power effectively as long as there is water around. Air conditioning systems are one of the many applications where TEMs have been successfully used.

Although a heat pump transports heat instead of cooling, it operates on the same principles as a refrigeration unit. An expansion valve and a compressor make up a heat pump. Gas is heated and compressed by the compressor until it reaches a turning point where it turns back into gas.

With the help of electricity, a heat pump can transport heat from the outside air into a building and subsequently back into a dwelling. Utilizing less heating and cooling equipment is the goal of this approach. Electricity is used by a heat pump to circulate chilled water. The fundamental refrigeration cycle is what is referred to as. The heat is then transferred to the evaporator coil via copper tubing after being brought in. Before returning to the house, the air that is being circulated passes straight over the coils. The temperature is decreased when the cool air passes over the coils. When the air is brought back inside, it is cooled and then fed through a coil that condenses water to release the heat.

After that, pipelines are used to pump the water back to the compressor. After receiving the cooled water, the compressor generates suction pressure, which activates the fan motor. As a result, the fan moves air about the space.

Temperature Regulator

Depending on the chosen set point, the controller adjusts the unit’s output. This means that depending on whether the required temperature is higher or lower than the setpoint, the unit’s output will differ. The device will run more quickly until the desired temperature is attained if the temperature is above the selected point. The opposite happens if the temperature is below the chosen point.

Condenser Coil

There are thousands of tiny pores in every evaporator coil. These little perforations prevent water droplets from touching the coils while allowing air to travel through the coil. The ground’s moisture is absorbed by the air as it moves through the coil.

Condensate Drain

Water is drained from the coils via condensation. The water would collect in the bottom because there isn’t much, if any, open space between them. Therefore, the extra water is sent out through the drain hole. The drain pipe is frequently made of stainless steel in order to stop corrosion in the coils.

Motor

The fan blades are driven by this motor. The motor may be direct drive or belt driven, depending on the size of the device. Direct drive motors require less frequent maintenance. However, if the belt drive is not well maintained, it needs to be inspected and the belts replaced.

Compressor

These motors assist the compressor in producing enough suction pressure. The pump impeller starts to rotate as soon as water enters the compressor. Friction causes an increase in rotational speed. The impeller eventually achieves its top speed and loses its ability to revolve. As a result, the compressor comes to a stop and starts producing suction pressure.

Suction Line

The tube that joins the blower and compressor is known as the suction line. The air is forced through the tube when the blower is operating. A stream of chilly air enters the ductwork as a result.

Thermally Driven Air Conditioning Systems: Advantages

Lower Expenses: Gas prices are currently low, but power costs are high. Compared to electrically determined blowers, thermally determined chillers provide cooling at lower energy costs. This is because they don’t use power to run; instead, they use gas and solar energy. As a result, power expenditures are eliminated and request fees are reduced.

Solar Based: Thermally determined chillers are also practicable when used with effective solar panels, which allows for important gas use balances and greater ecological performance.

Baseload Capacity: Thermally determined chillers can be driven by gas or by the sun. The combination of the two energy sources suggests that these chillers are capable of meeting firm cooling load factors without the need for reinforcement.

Reliable: Compared to electrically determined mechanical fume blowers, thermally determined chillers have less complex components and a far longer planned life. Additionally, solar panels are dependable, providing a practical on-site energy source supported by natural gas that is not susceptible to power outages or peak summer demand limits.

Effective: Two-stage impact chillers powered by the sun provide greater cooling than comparable solar structures. The structure can unquestionably receive more cold water for a given rooftop area by using a heated approach. When appropriate, waste intensity can also be properly collected and used as “free” pool or DHW pre-warming.
