Question

How much kW is in 1.5 ton AC?

Answer 1

Let's break this down carefully:

When you ask **"How much kW is in 1.5 ton AC?"**, you're essentially asking **how much cooling power** (in kilowatts) an air conditioner with a **1.5-ton** capacity has.

### Step 1: Understand what "ton" means in air conditioning

In air conditioning, a **ton** doesn't refer to weight.  
Instead, it is a unit of **cooling capacity**.

- **1 ton of cooling** = the amount of heat required to melt **1 ton (2000 pounds)** of ice in **24 hours**.
- This is standardized as:
  \[
  1 \text{ ton} = 12,000 \text{ BTU/hour}
  \]
  (where BTU = British Thermal Unit).

So:
- **1 ton = 12,000 BTU/hour**
- **1.5 ton = 1.5 × 12,000 = 18,000 BTU/hour**

---

### Step 2: Convert BTU/hour to kilowatts (kW)

Now, we need to convert **BTU/hour** into **kilowatts (kW)**.

**Conversion factor**:
\[
1 \text{ kW} = 3412 \text{ BTU/hour}
\]
Thus:
\[
\text{kW} = \frac{\text{BTU/hour}}{3412}
\]

Now plugging in the values:
\[
\text{kW} = \frac{18,000}{3412}
\]
\[
\text{kW} ≈ 5.275
\]

Thus, a **1.5-ton AC** has a **cooling capacity of approximately 5.28 kW**.

### Step 3: Summary

| AC Tonnage | Cooling Capacity (BTU/hr) | Cooling Capacity (kW) |
|:---|:---|:---|
| 1 Ton | 12,000 | ~3.52 kW |
| 1.5 Ton | 18,000 | ~5.28 kW |
| 2 Ton | 24,000 | ~7.03 kW |

---

### Step 4: Important Clarifications

- The **5.28 kW** figure is **cooling output**, not the **power consumption**.
- **Actual electricity consumption** depends on the **efficiency** (EER or SEER ratings) of the AC.
  - A **high-efficiency** 1.5-ton AC may **consume less power** while delivering the same cooling.
  - Typically, a **1.5-ton split AC** might **consume** between **1.2 kW to 2 kW** of **electric power** during operation, depending on its efficiency.

---

### Final Answer:
✅ **A 1.5-ton air conditioner provides about 5.28 kW of cooling capacity**.  
✅ **Its electricity consumption** will be **lower than 5.28 kW**, depending on its efficiency.
