Air conditioning system

Abstract

An air conditioning system that can perform stable temperature / humidity control and in which the capacity of a freezing machine and energy consumption can be reduced. A cold water supply line (11) and a return cold-water supply line (12) are connected to a cooling-cum-heating coil (3). A warm water supply line (14) is connected to a heating coil (5). The amount of water supplied from the cold water supply line (11) or the return cold-water supply line (12) to the cooling-cum-heating coil (3) is controlled so that the humidity of air to be treated is a desired set humidity. When the amount of humidification is insufficient, the amount of warm water supplied from the warm water supply line (14) to the heating coil (5) is controlled. Further, the amount of water supplied from the cold water supply line (11) to the cooling-cum-heating coil (3) and the amount of return cold-water supplied from a return cold-water supply line (18) to a reheating coil (6) are controlled so that the temperature of the air to be treated is a desired set temperature. When the amount of reheating heat is insufficient, the amount of warm water supplied from the warm water supply line (16) to a second reheating coil (7) is controlled.

Description

technical field [0001] The present invention relates to an air-conditioning system for adjusting the temperature and humidity of air to be processed, and more particularly to an improved air-conditioning system capable of achieving stable temperature and humidity control, reduction in refrigerator capacity, and energy saving. Background technique [0002] In electronic industry factories, precision machinery industry factories, food storage warehouses, experimental animal breeding rooms, biological clean rooms, etc., since it is necessary to maintain a constant indoor environment such as temperature and humidity, it is necessary to use timely temperature control. Humidity-regulated air conditioning system. [0003] As such an air conditioning system, there is a system disclosed in Patent Document 1 or Patent Document 2, for example. That is, the invention described in Patent Document 1 or Patent Document 2 utilizes the cooling capacity of the outside air in winter, so the ...

AI Technical Summary

Problems solved by technology

[0007] However, in the invention described in Patent Document 1 or Patent Document 2, in order to make the distribution of the outside air supplied to the room uniform, a water humidifier must be installed in the corresponding place , therefore, there is a problem that the cost of piping construction for transporting air increases

In addition, when the water is dispersed in the room, it may cause an accident, and there is a problem that it is necessary to install a space and the uniformity of temperature and humidity is difficult.
