Single-span air conditioning system

Abstract

The present invention aims to provide a single-span air conditioning system which has the following advantages: reduced space, easy construction, capability of realizing energy saving of a comfortable air conditioner and low cost. The single-span air conditioning system which performs air conditioning on each air conditioning space (S) between main beams is provided with an air conditioner (20) that is provided with a first coil pipe (23). The air conditioner (20) causes returned air or mixed gas of return air and outer air to generate heat exchange with heat medium or coolant of the first coil pipe (23) and utilizes the mixed air as air for the air conditioner. Simultaneously the air for the air conditioner is supplied to the air conditioning spaces (S) between the main beams.

Description

Technical field [0001] The invention relates to a single-span air conditioning system. Background technique [0002] Office buildings and other buildings usually have air conditioners on each floor. Due to the large range of air conditioners, large air conditioners or mechanical rooms are required, which is troublesome for construction. In addition, ordinary air conditioners use forced convection of cold or hot air to achieve air conditioning. Therefore, uneven temperature is likely to occur in floors. In order to eliminate such unevenness, expensive and complicated air conditioning control is required (see Patent Document 1 ). [0003] current technology: [0004] Patent Document 1: Japanese Patent Laid-Open No. 60-191157; [0005] Patent Document 2: Japanese Patent Laid-Open No. 7-318098; [0006] Patent Document 3: Japanese Patent Application Laid-Open No. 4-45331. Summary of the invention [0007] Cold and warm water type air conditioners have a limit to reduce operating costs un...

AI Technical Summary

Problems solved by technology

[0002] Office buildings, etc. usually have air conditioners on each floor. Due to the large range of air conditioners, large air conditioners or mechanical rooms are required, and the construction is troublesome.

And common air conditioner is to utilize the forced convection of cold wind or hot wind to realize air-conditioning, so the situation of uneven temperature easily takes place in the floor, in order to eliminate the situation of such unevenness, need expensive and complicated air-conditioning control (refer to patent document 1 )
