Description
Technical field
The present invention relates to the apparatus of air conditioning, it is more particularly to a kind of for central air-conditioning can energy saving
Electricity-saving appliance.
Background technology
At present central air conditioner cold source system design all adopt constant flow mode.This cold source system
Design is simple, it is not necessary to complicated automatic control technology, it is only necessary to set leaving water temperature and return water temperature,
Leaving water temperature and return water temperature adjust automatically working condition of the cold source system according to setting.
According to the design data of air-conditioner host, have between chilled-water flow maxima and minima and compare
Big regulation space.In fact, when ambient temperature or air conditioning terminal load change, chilled water
Supply and return water temperature, the temperature difference, pressure reduction and flow with cooling water all changes therewith.When ambient temperature or sky
When adjusting end load to reach human comfort's temperature, whole system lies substantially in stable working condition,
The work of refrigeration host computer is also interruption.A change is there is between return water temperature, leaving water temperature not
The big temperature difference.If central air conditioner system global design closes existing and working properly, this temperature approach typically can
Between return water temperature, the leaving water temperature value of refrigeration host computer setting, without departing from setting value.Low-temperature receiver system
Setting value also low rc～3 DEG C of the setting value of temperature often than specifying, so there is during system design
Larger energy dissipation.According to actually detected, the temperature of chilled water often reduces rc, its system energy consumption
27% will be increased.
Than larger, remaining time is interruption to the workload for the previous period of central air-conditioning refrigeration host computer start
Sex work.The energy consumption of central air-conditioning is relevant with actual environment temperature, when ambient temperatures are low, refrigeration
Main frame is just short in the start leading portion working time；When ambient temperature is high, refrigeration host computer is in start leading portion work
Make the time just long；When supply and demand reaches it is in a basic balance when, refrigeration host computer is then in unloaded state or underloading shape
State.Water circulation system is constantly in constant flow running status, and refrigeration system and water circulation system are in design
When be according to cold air usable floor area and ambient temperature more than 38 DEG C when maximum with air conditioning quantity configure,
It is exaggerated 20% surplus on the basis of actual disposition according to an international practice simultaneously.In actual use,
The working time of central air-conditioning state more than 38 DEG C in maximum cold air usage amount and ambient temperature is very
It is few.Central air conditioner cold source Design of Automatic Control System is simple, the setting value of temperature when cold source system is designed
Also lower i DEG C than the setting value of regulation～3 DEG C, the temperature of chilled water often reduces rc, its system energy
Consumption will increase by 27%.Refrigeration system and water circulation system are according to cold air usable floor area and ring in design
Maximum when border temperature is more than 38 DEG C is configured with air conditioning quantity, while actually matching somebody with somebody according to an international practice
20% surplus is exaggerated on the basis of putting, very big energy waste has been thereby resulted in.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the task of the present invention to be to provide a kind of central hollow and adjust
Electrical equipment, using intelligent automatic tracking control technology, it solves the design of central air conditioner cold source system
Temperature is lower, also reduce chilled water temperature so that system energy consumption is greatly increased, and causes energy waste
Problem.
