Abstract
The invention provides a novel data center hybrid refrigeration design method. According to the mechanical compression refrigeration mode, when the outdoor temperature is higher than 20 DEG C, a compressor is started for refrigeration, and the demand for indoor heat dissipation is met; according to the low-temperature energy-saving mode, when the outdoor temperature is lower than 10 DEG C, the compressor system is switched automatically to make an energy-saving pump operate on the condition that the indoor refrigeration demand is met, energy consumption of a unit is greatly reduced, and the yearly natural refrigeration operating time is prolonged. Compared with the prior art, a traditional economical air conditioner is effectively combined with natural refrigeration which is quite popular nowadays, the economical efficiency and reliability of the traditional air conditioner are obtained, and meanwhile outside natural cold can be fully utilized. A frequency conversing and energy saving pump circulation module is additionally arranged in the same unit, and on the premise of fully utilizing outside natural cold, the three operating modes of mechanical compression refrigeration, hybrid refrigeration and natural cold energy conservation can be provided finally with refrigeration of the compressor as a supplement.
Description
Technical field
The present invention relates to data center refrigeration design field, the specifically method for designing of a kind of new types of data center hybrid refrigeration.
Background technology
Target for energy-saving and emission-reduction is specify that in " 12 " planning of China.But at present along with largeizationr of data center's scale, increasing information technoloy equipment and corresponding auxiliary erection of equipment are come in, and this means that the energy resource consumption that data center produces is also increasing.The problem balanced how is kept to become present stage Constructing data center person and the common problem inquired into of users between data center's scale and energy consumption.
The refrigeration modes of data center constantly develops, and from air-cooled to water-cooled, then adds water-cooled to air-cooled, and water way of energy storage.The refrigeration modes that the many employings of small-sized data center below current 3000 square meters are air-cooled.But along with the development of domestic cloud computing, large-scale and ultra-large type data center becomes future developing trend.Air-cooledly cannot meet these large-scale data centers, on the contrary, the water cooling air conditioning system that refrigerating efficiency is higher can meet the demand of these large-scale data centers to the refrigeration of lasting rising.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the method for designing of a kind of new types of data center hybrid refrigeration is provided, the data center's refrigeration solution under collection mechanical compression refrigeration, hybrid refrigeration, naturally cold energy-conservation three kinds of operational modes.
Technical scheme of the present invention realizes in the following manner, and its method is as follows:
Mechanical compression refrigeration pattern: when outdoor temperature is greater than 20 DEG C, enable compressor and freeze, meet indoor radiating demand;
Low-temperature energy-saving pattern: when outdoor temperature is less than 10 DEG C, under satisfied indoor refrigeration demand condition, automatic switchover compressor assembly enters energy-saving pump and runs, and greatly reduces units consumption, improves the annual natural cold operation time;
Hybrid refrigeration pattern: except mechanical compressor refrigerating operaton and low-temperature energy-saving pattern refrigerating operaton two kinds of patterns, newly increase hybrid refrigeration pattern; When outdoor temperature≤20 DEG C, hybrid refrigeration pattern can be opened, be run by variable frequency pump auxiliary compressor, save compressor power consumption, reduce condensation temperature, improve refrigerating capacity, increase systematic energy efficiency ratio.
Hybrid refrigeration pattern is set; When outdoor temperature≤20 DEG C, hybrid refrigeration pattern can be opened, be run by variable frequency pump auxiliary compressor, save compressor power consumption, reduce condensation temperature, improve refrigerating capacity, increase systematic energy efficiency ratio.
Compressor cooling+natural cooling source, energy-saving and cost-reducing, embody green machine room theory, reach when imposing a condition, starting energy-saving cooling system, reduces units consumption; Intelligent controller automatically switches to refrigeration mode; Do not introduce new wind, not by outside air quality influence, range of application is expanded greatly; Outdoor temperature is lower, and energy-saving effect is better.
Energy-saving and frequency-variable pump loop module is added in same set of refrigeration unit, making full use of under extraneous naturally cold prerequisite, with compressor cooling as a supplement, finally can provide mechanical compression refrigeration, hybrid refrigeration, naturally cold energy-conservation three kinds of operational modes, each is local can be applied in the whole nation like this.In the north that annual temperature is lower, energy-saving effect is up to more than 50%.Even if in In Middle And Lower Reaches of Changjiang River, efficiency also can promote 30%.
Advantage of the present invention is:
The method for designing of a kind of new types of data center of the present invention hybrid refrigeration compared to the prior art, by traditional economic air-conditioning and now popular naturally cold effective combination, possess the economic reliability of traditional air conditioner on the one hand, the naturally cold of the external world can have been made full use of simultaneously.In same set of unit, adding energy-saving and frequency-variable pump loop module, making full use of under extraneous naturally cold prerequisite, with compressor cooling as a supplement, finally can provide mechanical compression refrigeration, hybrid refrigeration, naturally cold energy-conservation three kinds of operational modes.As the heat management solution that a height is energy-conservation, stronger advantage is had in reliability, intellectuality, adaptability, rapid deployment, ease for maintenance etc., cut down the electricity charge of user in equipment operation simultaneously, help user's lifting means efficiency, reach the effect of energy-saving and emission-reduction.
