1. What is a Heat Pump Output Temperature Calculator?

Definition: This calculator determines the temperature change of a fluid or air in a heat pump system based on heat energy, mass, and specific heat capacity.

Purpose: It helps HVAC professionals and engineers predict the output temperature of heat pump systems for proper system design and evaluation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \Delta T \) — Temperature change (°F)
• \( Q \) — Heat energy (BTU)
• \( m \) — Mass of the fluid/air (lb)
• \( c \) — Specific heat capacity (BTU/lb·°F)

Explanation: The heat energy is divided by the product of mass and specific heat capacity to determine the temperature change.

3. Importance of Temperature Change Calculation

Details: Accurate temperature change prediction ensures proper heat pump sizing, efficient operation, and prevents system overload or underperformance.

4. Using the Calculator

Tips: Enter the heat energy in BTU, mass in pounds, and specific heat capacity (default 1.0 BTU/lb·°F for water). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical specific heat for water?
A: Water has a specific heat of 1.0 BTU/lb·°F. For air, it's approximately 0.24 BTU/lb·°F.

Q2: How do I find the heat energy (Q)?
A: Q can be calculated from heat pump specifications or measured directly from system performance data.

Q3: What if I'm working with air instead of water?
A: Use the mass of the air and adjust the specific heat capacity to 0.24 BTU/lb·°F.

Q4: Does this account for heat loss?
A: No, this calculates ideal temperature change. For real-world applications, consider system efficiency and heat loss.

Q5: How do I convert this to output temperature?
A: Add ΔT to your input temperature to get the output temperature.
