Production of chlorofluorocarbons (CFCs) has been phased out. Environmentally acceptable replacement compounds are therefore needed for use in existing medium and low temperature refrigeration applications. Refrigerant R134a or HFC-134a was developed to meet these needs. Refrigerant R134a or HFC-134a is a commercially available hydrofluorocarbon (HFC) refrigerant for use as a long-term replacement for R-12 in new equipment and for retrofitting medium temperature CFC-12 systems. This refrigerant takes a significant step forward in environmental protection by achieving an ozone depletion factor of zero. It is used in both automotive and commercial air conditioning applications. It is the common phase "environment friendly" replacement for R12 but does require system retrofit modifications. Enter the temperature in either F or C degrees and the returned result is the alternate temperature and determined pressure in Barg and psig.

Barg is the gauge read pressure. The term gauge signifies that the pressure has been read from a gauge that actually measures the difference between the pressure of the fluid or gas and the pressure of the atmosphere. Psig is equal to psis at sea level (14.7 psi). Psig (inches of mercury) is equal to psia – 14.7 at sea level. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi. Now that I have indicated that, it relieves a lot of pressure... Below the calculator is an approximate chart relationship of temperature to pressure. Be aware that various brands and conditons will cause variations. R134a Refrigerant Pressure Calculator R134a Pressure Temperature ChartFor most of us, electricity bill is needed just to check the final amount and make the payment. We at Bijli Bachao asked a lot of our acquaintances about how much they understand their electricity bills, and we found hardly a handful who did understand it. And in spite of understanding the bills, not many knew how much they are spending per unit (or 1 kWh) of electricity.

It is very important to know the per-unit cost of electricity as it helps us in understanding how much we are spending per appliance at our home. It is important to understand the monetary impact of any electricity efficiency measure we take. It is also important to understand various components of electricity bills and what is their contribution to the total electricity bill. In a bid to help people understand the same, we have created this online electricity bill calculator that will help people understand how much they spend on various appliances every month and how they can save by doing various activities. Please make sure that you read about the calculator below before using it. Please note that this tool currently works only for domestic tariffs. Click on this link: Domestic Electricity LT Tariff Slabs and Rates for all states in India in 2014 1) Select Utility: Once you login, the first thing you need to do is select utility. Select your state, district and utility and the system saves your information for the user session automatically.

2) Enter Units: Enter this value as shown on your electricity bill. This shows up as units consumed.4 ton ac units 3) Select Phase: Select if you have a three phase connection or single phase connection. air conditioning unit for apartmentThis information is also available on the electricity bill.what is a 4 ton ac unit 4) Connected Load: It is decided by the utility based on appliances you have at your home, please see our article on connected load to get more details.. It is also mentioned as sanctioned load, load, connected load, or approved load. If the load mentioned is in Watts (it is a number is 100s or 1000s) then divide it by 1000 and enter it. 1) Understand various components of your electricity bills. 2) Understand how much you are paying per unit (1 kWh) of electricity bill.

3) Understand how much you spend on various appliances like lights , air conditioner , refrigerator ,  tubelight , computer , set top box , fan , etc. Please note that we have taken approximate usage of these appliances based on how it is used normally in houses. Actual amount may vary as per your use. The values are just a representation. 4) Understand savings if you switch from inefficient to efficient appliances. Even these values are approximation based on general usage. We are in process of building tools to help you get to better values as per your consumption in future. The tool has been built with latest tariff data available from all the state electricity boards in India and has maximum information as available on internet and through our contacts who helped us with sample electricity bills from various states. Certain values have been rounded to have better readability and so it may not match exactly to your electricity bills but will be very close. 1) Energy Charge: This is the per unit electricity charge that you pay on your bill.

It is mostly defined slab wise and the cost increases as units on electricity bill increases. 2) Fixed Charge: This is mostly dependent on the connected load that the utility provides you. Connected load is typically calculated as sum of wattage of all the appliances that you have at your home. The utility allocates this much amount of electricity for your home and that is why the fixed charge is applicable. 3) Electricity Duty & Tax: This is the government tax for using electricity. Duty is applicable per unit of electricity consumption and tax is applied on the whole bill amount. 4) Meter Rent: Rent that you pay for having meter at your home. Rates are different for single phase and three phase connections. 5) Wheeling Charge: The tool also helps you find out how your bill gets impacted if you move from Reliance Energy to Tata Power in Mumbai. Wheeling charges are applicable for the switchover. 6) Minimum Monthly Charges: In some states if the consumption is less than a certain amount, minimum monthly charges are applicable, which means that the bill amount cannot be less than minimum monthly charges.

1) FAC (Fuel adjustment charge) or FCA (fuel cost adjustment) or FPPCA (Fuel and Power Purchase Cost Adjustment): This is the amount which utilities apply on bills based on varying price of fuel or Coal. Every month this value is different and is derived based on the current cost of Coal. Typically this a few paise per unit. 2) Arrears/Interest and Other Charges: If your electricity bill has old payment pending and interest on the same, or any other charges, then those will not match from the output of the tool to your electricity bill. Also check this video that can help you understand how many units your appliances are consuming: domestic LT (Low Transmission) connections with a connected load between 0 and 20 kW and has been validated for following states: Andhra Pradesh, Assam, Bihar, Chandigarh, Chattisgarh, Gujarat, Haryana, Karnataka, Kerala, Madhya Pradesh, Maharashtra, New Delhi , Rajasthan, Tamil Nadu, Uttar Pradesh and Uttarakhand.
