Chiller Fish Tank – Aquarium Temperature Regulator 853BTU 200W

A chiller is a refrigeration unit designed to produce cooling and lower temperatures. Chillers utilize water as the primary medium for heat exchange and cooling transfer. They are widely implemented in industrial applications for dissipating heat from machinery, ensuring equipment longevity, and maintaining operational efficiency.

When applied to aquaculture, chillers are known as Chiller Fish Tanks. These devices are crucial for regulating water temperature to optimal levels for fish cultivation, enabling rapid cooling.

A 200W / 853BTU chiller can cool approximately 34 liters of water from 30°C to 25°C in 1 hour.

Question:

How many liters of water can a 853 BTU or 200W water chiller cool to 25°C within 1 hour?

Calculation Data:

• Cooling Capacity: 200 Watts or 853 BTU/hour
• Target Temperature: 25°C
• Assumed Initial Water Temperature: 30°C → Required Temperature Drop: 5°C
• Specific Heat Capacity of Water = 4.186 J/g°C
• 1 liter of water = 1000 grams

Calculation Steps:

1. Energy Output by the Unit in 1 Hour:

$$200\text{Watts}\times 3600\text{seconds}=720,000\text{Joules}$$

2. Energy Required to Lower 1 Liter of Water by 5°C:

$$1000\text{grams}\times 4.186\times 5=20,930\text{Joules}$$

3. Calculation of Coolable Water Volume:

Liters of Water = 720,000 / 20,930 ≈ 34.4 LitersLiters of Water=20,930720,000​≈34.4Liters

✅ Summary:

A 200 Watt or 853 BTU chiller can cool approximately 34 liters of water from 30°C to 25°C within 1 hour.
