Understanding Air Conditioning: Technical Overview
Air conditioning systems work by removing heat and humidity from an indoor space and transferring it outdoors, thereby cooling and dehumidifying the air. The process relies on the principles of thermodynamics, specifically the refrigeration cycle, which involves four main components:
- Evaporator: Absorbs heat from indoor air as a low-pressure refrigerant evaporates, cooling the air that’s blown over the coils.
- Compressor: Compresses the refrigerant gas, raising its pressure and temperature, preparing it for heat expulsion.
- Condenser: Releases the absorbed heat to the outdoors as the high-pressure refrigerant condenses back into a liquid.
- Expansion Valve: Reduces the refrigerant’s pressure, allowing it to cool and return to the evaporator to repeat the cycle.
The refrigerant, typically a hydrofluorocarbon (HFC) like R-410A or the more eco-friendly R-32, is the working fluid that facilitates heat transfer. AC efficiency is measured by metrics like the Seasonal Energy Efficiency Ratio (SEER) or Energy Efficiency Ratio (EER), which indicate cooling output (in BTUs or watts) per unit of energy input (in watts).
Types of Air Conditioners
| Type | Description | Pros | Cons |
|---|---|---|---|
| Window AC | A single unit that fits into a window or wall opening. | Affordable, easy to install, compact. | Noisy, not suitable for large rooms. |
| Split AC | Comprises an indoor and outdoor unit. | Quieter, energy-efficient, better cooling. | Higher installation cost, requires more space. |
| Inverter AC | Uses variable-speed compressors to adjust cooling. | Energy-saving, maintains consistent temperature. | Expensive upfront cost. |
Key Technical Specifications to Consider
When choosing an AC, you’ll need to evaluate several technical parameters:
Cooling Capacity & Room Size
Measured in British Thermal Units per hour (BTU/hr) or tons (1 ton = 12,000 BTU/hr).
Determines how much heat the unit can remove. Oversizing or undersizing leads to inefficiency or discomfort.
| Room Size (sq. ft.) | Recommended AC Capacity (Ton) |
|---|---|
| Up to 120 sq. ft. | 0.75 – 1 Ton |
| 121 – 180 sq. ft. | 1.5 Ton |
| 181 – 250 sq. ft. | 2 Ton |
Energy Efficiency & BEE Star Ratings
ACs in India come with BEE Star Ratings, which indicate power consumption levels. The higher the rating, the lower the energy consumption.
| BEE Star Rating | Annual Power Consumption (1.5 Ton AC) |
|---|---|
| 1 Star | 1600-1700 kWh |
| 3 Star | 1100-1300 kWh |
| 5 Star | 750-850 kWh |
Compressor Type & Refrigerants
Compressor Types
- Rotary Compressor: Quieter, more efficient.
- Reciprocating Compressor: Noisier, but durable.
- Scroll Compressor: Used in high-capacity ACs.
Refrigerants to Consider
| Refrigerant | Global Warming Potential (GWP) | Ozone Depletion Potential (ODP) | Eco-Friendliness |
|---|---|---|---|
| R-22 | High | Yes | ❌ |

| Central AC | 24,000–60,000+ | 14–20 | 30–50 (indoor) | High (Professional) | Large homes, commercial |
| Ductless Mini-Split | 9,000–36,000+ (multi-zone) | 16–25 | 20–40 (indoor) | Medium (Professional) | Zoned cooling, retrofits |
| Evaporative Cooler | Varies (CFM-based) | N/A (no compressor) | 40–60 | Low (DIY) | Dry climates, open spaces |
Cooling Capacity Guidelines by Room Size
| Room Size (sq.ft.) | Cooling Capacity (BTU/hr) | Recommended System Type | Notes |
|---|---|---|---|
| 100–250 | 5,000–6,000 | Window, Portable | Small bedrooms, offices |
