Problems solved by technology

[0008] In the above air conditioning system, such as Figure 5 As shown in the table of , although the target air-conditioning capacity can be roughly achieved when the demand control level (the expected excess amount of electric power) is low, but when the demand control level is increased, comfort will be sacrificed in order to strictly adhere to the target power
[0009] In particular, the multi-connected air conditioners used in buildings generally control the humidity along with the temperature control. 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

Embodiment Construction

[0043] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0044] figure 1 The air conditioning system (1) shown in this embodiment is an air conditioning system (1) with a demand control device (10) for controlling the total power consumption of multiple air conditioning loads, including an air conditioning system (1) that mainly processes indoor sensible heat loads A device (20), and a humidity control device (30) mainly dealing with indoor latent heat load. That is, the air conditioning system (1) is configured to separately process the sensible heat load and the latent heat load in the room.

[0045] The air conditioner (20) includes a refrigerant circuit that performs a vapor compression refrigeration cycle, but the refrigerant circuit that performs a vapor compression refrigeration cycle is not shown in the figure. Such as figure 2 As shown, the air conditioner (20) is a so-called multi-connected air conditioner (...

Abstract

An air-conditioning system (1) comprising a demand controller (10) for controlling the total consumed electric energy of air-conditioning loads. To enhance the amenity during demand control the system (1) is provided with an air conditioner (20) having a coolant circuit and adapted to handle the sensible heat load in the room and a humidifier (30) having adsorbing members (32,33) and adapted to handle the latent heat in the room, and the humidity in the room is regulated by the humidifier (30) according to the demand control levels while controlling the evaporation temperature of the coolant circuit constituting the air conditioner (20).

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...
