PCT No. PCT/FI94/00310 Sec. 371 Date Apr. 30, 1996 Sec. 102(e) Date Apr. 30, 1996 PCT Filed Jul. 5, 1994 PCT Pub. No. WO95/02157 PCT Pub. Date Jan. 19, 1995A method and an arrangement for controlling heat transfer in a ventilation apparatus or an air conditioning apparatus, in which heat contained in exhaust air is recovered into supply air by means of a heat transfer circuit having fluid circulation. Additional heating or additional cooling energy is supplied to the heat transfer circuit when the heat transfer is insufficient for maintaining a desired temperature of the supply air. To optimize the heat recovery, the supply of additional heating or cooling energy is minimized by measuring the temperatures and fluid flows of the heat transfer fluid and of the additional energy.
