Tips for building a low carbon society
Comment on “ Green-energy communities sprouting up ” (China Daily Website, July 1)
Having spent 12 years in developing and designing renewable energy systems in China from Beijing to Nanjing to where I am now in Cixi, I still do not understand why we have all these high rise apartments and offices going up across China and still no insulation to stop the sun’s heat entering the building, which then requires air conditioning, like my hotel room, 24 hrs a day. In winter, we are all freezing because the heat we do put in, again by air conditioning systems, is lost through the walls and windows.
The energy waste in China is massive, so it’s time the PRC started to enforce two means of meeting a low carbon society. One is to enforce the use of insulation, as it is impossible to be added later. Second is to change all the heat-producing light bulbs and invest in LED replacements.

"If you don't have one with enough Btus, the air conditioner will have to work harder to cool the space and eventually it will either freeze up or the compressor will burn out," Gilliland said. If you Google "Btu chart for air conditioners," you can

“The decrease in airflow can prevent the unit from pulling in air and the unit can start to freeze up on the outside,” Woodberry said. “It can make your unit outside freeze over and look like a big ice cube.” Most filter manufacturers recommend
Services were stalled between Dum Dum and Girish Park for nearly four hours from 11.15am after an AC rake developed a fault. While the train was being pushed to the car shed from Dum Dum, a tree fell on the tracks, causing further delay.
No one has come up with a workable design that exhausts the warm air outside like an air conditioner, or brings in cold air in winter so the compressor doesn't have to work as hard. And from an energy efficiency perspective, it's crazy paying for
Is Your Air Conditioner Freezing Up?
Having your air conditioner freezing up is a problem that many people face at some point in the lifetime of their air conditioning system. An air conditioner freezing up can be caused by a number of factors and is not that uncommon of a problem.
One of the most common causes of an air conditioner freezing up is insufficient airflow through your evaporator coil. This can be caused by something as simple as a blockage, such as a plugged up air filter that prevents good airflow back to your system, or a malfunction that causes the evaporator fan (or “blower”) to stop working. Air conditioning relies on refrigerant being converted from a liquid state back into a gas in the evaporator coil (this is the “indoor coil” that sits on top of the furnace or handler in most systems). As the evaporator fan blows air across the indoor coil, the liquid refrigerant absorbs the heat from the air, thus cooling it as it is recirculated back through your home.
This process also causes the refrigerant to evaporate, changing it back into a gaseous state and allowing it to continue back through the refrigerant “loop”. If the evaporator fan is not working, the heat in the air is not being transferred to, and carried away by, the refrigerant. This will cause the coil to freeze up and will prevent your air conditioning system from doing its job.
There are a number of things that can cause the evaporator fan to stop working:
The blower motor (evaporator fan motor) may have failed. The fan relay may have failed, causing the blower motor to not operate. Your thermostat may have failed, causing the blower motor to not operate or the compressor in your air conditioner to not shut off. The compressor relay in your air conditioner may have frozen, causing the compressor to never stop running.Other potential causes of your air conditioner freezing up can be an improper refrigerant charge in your system’s condensing unit or excessively low outdoor temperatures. These are just a small number of potential causes that would result in your air conditioner freezing up.
If your air conditioner is freezing up, shut off your air conditioning system and allow it time for all of the ice to melt. Be sure to check your air filter as well, since a dirty filter can reduce the airflow required for the system to operate correctly. Once it has “thawed”, you can turn the system back on to see if it is functioning normally. If the problem persists, contact a trained HVAC Contractor in your area.
