Saving electricity on AC units and reducing the amount of greenhouse gas emission materials equivalent to CO2 gas

1. Introduction.

AC units are currently widely used by people around the world to produce cool indoor air temperatures, thus providing comfort for those who occupy them. However, AC units are also one of the components of electrical equipment, which also contribute to increasing the global temperature of the earth, when the artificial refrigerant material inside them leaks into the atmosphere. Artificial refrigerants that are generally still widely used in AC units include R22, R410a, R32, R407c. This artificial refrigerant material is one of the materials that has a carbon footprint with a capacity of hundreds to thousands of times that of CO2 gas. This carbon footprint figure is an indicator that shows how much greenhouse gas material equivalent to CO2 gas will be produced when a number of significant units of the artificial refrigerant material are released into the atmosphere. The emergence of greenhouse gas emission material equivalent to CO2 gas caused by the AC unit, when the C unit uses electrical energy when. AC units that use large amounts of electrical energy per unit of time or are said to be wasteful of electricity, then the amount of greenhouse gas emission material equivalent to CO2 gas that will be produced will also be large and affect global climate chaos.

2. Greenhouse gas emission material equivalent to CO2 gas that makes the climate even more chaotic.

The more greenhouse gas emissions equivalent to CO2 gas accumulate in the earth's atmosphere in large quantities, the greater the layer of gas that can trap heat like CO2 gas which can increase the temperature of the earth globally. One of the materials that can produce greenhouse gas emissions equivalent to CO2 gas is artificial refrigerant material. The amount of gas that traps heat in the atmosphere has clearly made global climate change even more chaotic, with various very bad impacts on life and will last for a long time, more than 100 years into the future.

3. Sources of power generation and greenhouse gas emission materials produced are equivalent to CO2 gas. The sources of power generation that are currently widely used by countries in the world are power generation systems that produce greenhouse gas emission materials in large quantities, according to the large capacity of the electricity generated. One of the sources of power generation that uses coal as raw material has produced greenhouse gas emission materials equivalent to CO2 gas into the atmosphere by 10-20%, while the concentration of CO2 gas in nature is 0.036%. The equivalent of 1 kWh of electrical energy produced from a power plant using coal will produce greenhouse gas emission materials equivalent to CO2 gas = 1.2 kg CO2.

4. What is the estimated probability of the potential amount of greenhouse gas emission materials equivalent to CO2 gas, which can be produced from an AC unit from its electricity consumption.

By making an estimate of the duration of the AC unit material with a certain capacity, and the duration of the AC unit being run in one month, the estimated amount of potential greenhouse gas emission material equivalent to CO2 gas can be known with one simple calculation.

a. For 1 AC unit with a capacity of = 1 PK, and its electricity usage for 200 hours/month using HCFC R22 refrigerant material.

The estimated probability of the amount of potential greenhouse gas emission material equivalent to CO2 gas that can be produced is = 222 kg of CO2 equivalent/month, or = 2,664 kg of CO2 equivalent/year/unit.

b. For 1 AC unit with a capacity of = 1 PK, and its electricity usage for 200 hours/month using HFC R32 refrigerant material.

The estimated probability of the amount of potential greenhouse gas emission material equivalent to CO2 gas that can be produced is = 206 kg of CO2 equivalent/month, or = 2,472 kg of CO2 equivalent/year/unit.

c. For 1 AC unit with a capacity of = 1 PK, and electricity usage for 200 hours/month using HFC R410a refrigerant material. The estimated potential amount of greenhouse gas emission material equivalent to CO2 gas that can be produced is = 212 kg of CO2 equivalent/month, or = 2,554 kg of CO2 equivalent/year/unit.

5. Refrigerant conversion in reducing the potential amount of greenhouse gas emission material in AC units.

One way to reduce electricity consumption in AC units is by converting its refrigerant, namely replacing artificial refrigerant with natural climate-friendly refrigerant.

a. Estimated amount of potential reduction in greenhouse gas emission material equivalent to CO2 gas in a 1 PK AC unit using HCFC R22 = 19%/month/unit, or = 228%/year/unit.

b. Estimated amount of potential reduction in greenhouse gas emission material equivalent to CO2 gas in a 1 PK AC unit using HFC R32 = 23%/month, or = 276%/year/unit.

c. Estimated amount of potential reduction in greenhouse gas emission material equivalent to CO2 gas in a 1 PK AC unit using HFC R410a = 26%, or = 312%/year/unit.

d. Other advantages of converting refrigerants in an AC unit are the reduction in electrical power, as well as the reduction in electricity costs that occur continuously as long as the AC unit is not damaged.

6. Conclusion.

The refrigerant material conversion program carried out on the AC unit significantly and measurably can reduce the amount of greenhouse gas emission material caused by the use of electricity to drive the AC unit. This activity can also be carried out on other cooling machine units.
