Abstract
The invention discloses a chilled water pipeline for a central air conditioner, which is characterized in that firstly, the chilled water from a water chilling unit flows into fresh air handling units in air conditioned areas so as to process outdoor fresh air and carry out moisture load and partial thermal load by a fresh air handling chamber; then, the chilled water flows through indoor air conditioners in the air conditioned areas; and finally, the chilled water flows back to the water chilling unit by a water circulating pump. So that the loads of the indoor air conditioners are reduced, and the area of a coiled tube is reduced; the coiled tube runs under a dry working condition, therefore, a condensed water pipeline is saved, and the indoor environment is more sanitary; and because the indoor air conditioners are not required to remove the moisture excess of indoor air, the water supply temperature and the backwater temperature of the chilled water are increased, and the energy efficiency ratio of a refrigerating system is improved, therefore, the refrigerating system is more energy-saving. A certain relationship exists between the change in fresh air load and the change in moisture load, the air conditioner zoning is performed, and the air conditioner areas are connected by parallel pipelines, therefore, the air conditioners can be subjected to zoning control according to the changes in fresh air loads and moisture loads of different air conditioner areas, and the air handling situation of the fresh air handling unit is changed according to the running changes of the indoor air conditioners, so, the adaptive capability of the system is strong.
Description
Technical field
The present invention relates to a kind of central air conditioning equipment, particularly a kind of chilled water pipeline of central air-conditioning.
Background technology
Circulated refrigerated water is main refrigeration modes in central air conditioner system, and primary structure comprises water circulating pump, handpiece Water Chilling Units, new blower fan group and room air conditioner, relies on the chilled water pipeline to connect between them.In the at present common above-mentioned parts of central air-conditioning, new blower fan group is in parallel with chilled water pipeline between the room air conditioner, heat, humidity load in the room air conditioner process chamber, new blower fan group is only handled new wind load, there is following shortcoming in this structure: the one, for removing indoor surplus wet amount, the chilled water supply and return water temperature is lower, and systematic energy efficiency ratio is low; The 2nd, the room air conditioner coil surface easily produces condensate water, occurs bacteria breed easily and leak polluting the problem of ceiling; The 3rd, the factor that mainly causes of new wind load and indoor humidity load is an indoor occupant, and two loads are interrelated, use new blower fan group and room air conditioner parallel pipeline, and new blower fan group can not automatically be changed according to the variation of room air conditioner load, is unfavorable for energy-conservation; The 4th, whole hot humidity loads in the room air conditioner process chamber, the coil area that needs is bigger, and it is big to take up room.
In sum, at the deficiencies in the prior art, need a kind of central air-conditioning chilled water pipeline especially, to solve above-mentioned problem.
Summary of the invention
The objective of the invention is to: the problems referred to above that exist at existing central air-conditioning, for the user provides a kind of energy-conservation, health, adaptive ability is strong, cost is low, reliability is high central air-conditioning chilled water pipeline.
The objective of the invention is to realize by the enforcement following technical proposals:
A kind of central air-conditioning chilled water pipeline, be used for connecting the closed circuit that handpiece Water Chilling Units, water circulating pump, the new blower fan group of conditioned area and room air conditioner are formed, described new blower fan group and room air conditioner constitute by fan coil and air-conditioning unit, it is characterized in that, described fan coil and air-conditioning unit are connected in parallel to each other, between water circulating pump, handpiece Water Chilling Units, new blower fan group, the room air conditioner by the chilled water pipeline in regular turn with its series connection.
In one embodiment of the invention, described new blower fan group and room air conditioner are provided with several in each conditioned area, constitute some groups of new blower fan cohorts and room air conditioner group respectively; Pass through the parallel connection of chilled water pipeline between each new blower fan group in the new blower fan cohort, pass through the parallel connection of chilled water pipeline in the room air conditioner group between each room air conditioner, connect by the chilled water pipeline between new blower fan cohort and the room air conditioner group.
In one embodiment of the invention, it is characterized in that described conditioned area is provided with several, be connected in parallel to each other by the chilled water pipeline between the different conditioned area.
The invention has the advantages that: from the chilled water of handpiece Water Chilling Units, be introduced into the new blower fan group in the conditioned area, the outer new wind of process chamber is by humidity load and portion of hot load in the new wind process chamber, the cooling water room air conditioner in the conditioned area of flowing through is then sent handpiece Water Chilling Units back to through water circulating pump again.The room air conditioner load reduces like this, and coil area reduces; Condensate line is saved in the dried industrial and mineral operation of coil pipe, and simplicity of design is reduced investment outlay; Do not had condensate water, indoor sanitary condition is improved greatly; Because room air conditioner does not need to remove the surplus wet amount of room air, the chilled water supply and return water temperature improves, and the refrigeration system Energy Efficiency Ratio improves, and system is more energy-conservation.The factor that mainly causes of new wind load and indoor humidity load is an indoor occupant, there are certain relation in the variation of new wind load and the variation of humidity load, with air conditioning zoning, adopt parallel pipeline between each conditioned area, can directly control according to the situation of change subregion of zones of different new wind load and humidity load, the situation that new blower fan group is handled air changes according to the variation that room air conditioner moves, and the system self-adaption ability is strong.The present invention who adopts said structure compared with prior art has and can make central air-conditioning energy, health, adaptive ability is strong, cost is low and reliability is high advantage.
Description of drawings
Fig. 1 is the structured flowchart of a kind of central air-conditioning chilled water pipeline of the present invention.
Number in the figure explanation: constitute the fan coil 3 of room air conditioner in the new blower fan group 2 in the handpiece Water Chilling Units 1, air conditioning area, air conditioning area, constitute the air-conditioning unit 4 of room air conditioner in the air conditioning area, water circulating pump 5.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
