Description
Technical field
The invention belongs to air conditioner cold accumulation field of energy-saving technology, and in particular to a kind of phase change cold-storage Air Conditioning Facilities.
Background technique
With popularizing for air-conditioning, electricity consumed by air-conditioning also gradually increases in the ratio of building energy consumption.In summer, sky
The energy consumption of tune accounts for the 85% of building energy consumption, keeps the peak-valley difference of electricity usage larger, and peak times of power consumption electricity consumption occur, supply falls short of demand,
The phenomenon of electricity consumption low peak period electricity consumption surplus.And since country is proposed the Power policy of encouragement peak load shifting, to make full use of
Therefore electric power resource, cold accumulation air-conditioner are favored by people.
So-called cold accumulation air-conditioner works in night electricity consumption low peak period, at this time and the air conditioner load lower period, air-conditioning
Host refrigeration and by cooling capacity savings get up, cooling capacity is released to peak times of power consumption on daytime, to meet peak times of power consumption
Air conditioner load needs.In this way, most of power consumption of air-conditioning is transferred to night, and daytime only air-conditioning ancillary equipment running,
Realize " peak load shifting " of air conditioning electricity load.
Existing central air conditioner system is to design by peak load, and there are certain allowances.Under regular situation, in portion
System can be run in inefficient area (when especially less than 60% load) when dividing load, and energy consumption is higher.Central air conditioner room is mainly used
Electric equipment includes: refrigeration host computer, chilled water pump, cooling water pump and cooling tower.Wherein 60% or more energy consumption is refrigeration host computer energy
Consumption.The comprehensive energy efficiency COP of computer room is improved, optimal state is to make this four big electrical equipment, under different load state, all
It can be run in high efficient district.Wherein, host efficiency is most importantly improved.Major measure has two o'clock: one is to try to reduce cooling water
Temperature；Second is that formulating reasonable booting strategy, makes host in the operation of different load state, can be run in high efficient district.Water pump
This two o'clock is all surrounded with the control strategy of cooling tower to formulate.
Current Air Conditioning Facilities lack the accurate detection to above-mentioned four big equipment running status, realize to equipment operation extensive
Formula management；Or without formulating the booting strategy that host can be made to keep efficient operation again simultaneously according to end load variation, or control
Means processed are limited, cannot perform effectively；Or system debug is not in place, does not exclude defect, causes system longtime running in spite of illness；Row
Industry specification payes attention to the efficiency of host, ignores computer room comprehensive energy efficiency.
