Refrigeration COP and Heat Pump Calculator

Calculate coefficient of performance: COP_R = Q_L/W = T_L/(T_H−T_L) (ideal). Typical actual COP_R: 2–6 for air conditioning. COP_HP = 1 + COP_R. Convert to SEER = 3.412 × COP_R.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How to Use

Enter the values for the patient or scenario you are assessing. Calculate coefficient of performance: COP_R = Q_L/W = T_L/(T_H−T_L) (ideal). Typical actual COP_R: 2–6 for air conditioning. COP_HP = 1 + COP_R. Convert to SEER = 3.412 × COP_R. Use the refrigeration cop result to inform your clinical assessment.
