Results

COP_ref = T_c/(T_h−T_c).
9
COP_hp = T_h/(T_h−T_c).
10
W = Q_c/COP_ref.
111.111111W
Q_h = Q_c + W.
1,111.111111W

At a glance:COP_ref = T_c/(T_h−T_c); COP_hp = T_h/(T_h−T_c). Complements carnot-cycle and carnot-efficiency.

Formula

COP_ref = T_c/(T_h−T_c).

$$\text{COP}_R = \frac{T_c}{T_h - T_c} = \frac{Q_c}{W}, \quad \text{COP}_{HP} = \frac{T_h}{T_h - T_c} = \text{COP}_R + 1$$

How to Use

  1. Enter T_c, T_h and cooling capacity.
  2. The tool returns COPs and power.

Case Studies

T_c=270, T_h=300, Q_c=1000 W

COP_ref=9, W≈111 W.

FAQ

COP > 1?

Yes — a heat pump moves more heat than the work it consumes.
