I have always enjoyed hearing the ambient roar of an air conditioner while I'm falling asleep, so I decided to record mine and upload it. Enjoy :] The sweltering heat of the summer months is a good reminder of the value of an air conditioning unit. In parts of the country such as Las Vegas, Phoenix and Arizona, summer highs can reach over 100 degrees Fahrenheit. On the other side, par When the heat of summer is beating down, nothing takes the edge off like the refreshing chill of air conditioning. If you’re one of the lucky Americans with central air conditioning in your home, you already know what a difference it makes Let’s be honest— in hot, humid weather, it doesn't take long to feel like you’re trapped in a sauna, and you'll do almost anything to get some relief.

The COVID-19 outbreak and resulting quarantine reminded us all that it's not pleasant to There’s nothing worse than a night of restless sleep — plagued by the discomfort of trying to get comfy or find that right balance between too many blankets and not enough. There’s perhaps no season that’s more meddlesome to one’s sleep tha Your air conditioning options for the hotter months range from portable units to central duct systems with large fans. When it comes to chilling out, nothing beats an air conditioner on a hot day. It’s fair to say, though, that not all air A great air conditioning unit should be efficient, intuitive to use, and affordable. We researched the best air conditioners so you can pick the perfect one. Our editors independently research, test, and recommend the best products; you can Air-conditioning systems keep getting better with each passing year, but of course not even the best can last forever.

The new station therefore conforms to the strictest industry standards governing air conditioning maintenance and recharge systems for the new R744 (CO2) refrigerant. These new systems are intended to minimise pollution and to reduce the risk of fire in the event of leaks, and are radically different in design from previous generations of recharge station that used R134a and R1234yf refrigerants.

This post explains some of the hazards and provides very general guidance on reducing them. 1. Asphyxiation.

The company designs, produces and distributes branded Refrigera® valves for refrigeration systems and branch joints and headers for VRF air conditioning

Read full profile We have become so accustomed to air conditioning that we feel like If you’re in the market for a new central AC system, don’t buy one that uses R22 refrigerant. As of January 1, 2020, production and importing of R22 refrigerant will be banned.

Carbon dioxide (R744) is over a thousand times less harmful on the atmosphere than the conventional R134a refrigerant. It has an excellent cooling capacity, it is not flammable and readily available worldwide at low cost. Leading bus manufacturers already launched the first models with R 744 air conditioners.

CO2 requires operating pressures up to ten times higher than R134a. This is because most R-744 systems operate as a transcritical system.
