AIR CONDITIONING SYSTEM

Japanese Patent JP2018048784

A

PROBLEM TO BE SOLVED: To provide an air conditioning system capable of sufficiently enhancing comfort of a user.SOLUTION: An CPU calculates a target air volume V2t of an indoor fan by substituting a heat recovery temperature difference ΔTb2 and a calculated refrigerant heat absorption amount Q2R and indoor upper part air specific heat Cp2 and an indoor upper part air density ρ2 read out by a subroutine of heat recovery operation control into a numerical expression. Then, the CPU sets rotational frequency N2 of a second indoor fan corresponding to the calculated target air volume V2t. Specifically, the CPU transmits the calculated target air volume V2t to a second indoor unit via a communication part, and the second indoor unit which has received the target air volume V2t drives the second indoor fan at the rotational frequency N2 so that the air volume by the rotation of the second indoor fan becomes the target air volume V2t.SELECTED DRAWING: Figure 6
