Air-conditioning system

Abstract

An air conditioning system (1) including a demand control device (10) that controls the total amount of the working power of a plurality of air conditioning loads is provided with, in order to improve comfortableness under demand control, an air conditioner (20) including a refrigerant circuit and dominantly processes an indoor sensible heat load and a humidity controller (30) which includes adsorption members (32, 33) and dominantly processes a latent heat load. According to a set level of a plurality of demand control levels, the evaporation temperature of the refrigerant circuit composing the air conditioner (20) is controlled while the indoor humidity is adjusted by the humidity controller (30).

Description

technical field [0001] The invention relates to an air-conditioning system with a demand control device, and the demand control device controls the total power consumption of a plurality of air-conditioning loads. Background technique [0002] Hitherto, there has been a demand control device that controls load so that peak power does not exceed a certain range as a device for realizing energy saving in facilities such as buildings (for example, refer to Patent Document 1). Generally speaking, the demand control device is a device that controls the operation of the load machine so that the average power used during a certain period of time (usually 30 minutes) does not exceed the contract power signed with the power company. When the contracted power is to be exceeded, the demand control device plays the role of issuing a peak cut command of the load to the air conditioner of each room in the building (multitype air conditioner for the building) , The ability to control ligh...

AI Technical Summary

Problems solved by technology

[0006] In the air-conditioning system described above, as shown in the table of FIG. 5, although the target air-conditioning capacity can be substantially achieved when the demand control level (the expected excess amount of electric power) is low, when the demand control level is increased, in order to strictly Adhere to target power at the expense of comfort

[0007] In particular, multi-connected air conditioners used in buildings generally follow the temperature control to control the humidity. Therefore, in summer, once the set temperature is changed by using the switch control of the indoor unit, the humidity will also increase significantly, so that the comfort is obvious. reduce
