Description
Technical field
The present invention relates to the air conditioner in machine room operation control system, especially for reaching the precision temperature control of machine room, the machine room air-conditioning energy-saving operation control system of environmental protection and energy saving.
Background technology
It is unreasonable that the architectural characteristic of the interior common split-type air conditioner of existing machine room makes it exist operation to exist in the specific environment of machine room, manage situation not in place, because artificial factor, can't accurately hold the actual distribution of temperature and setting rationally, the particularly setting of operating temperature, estimate by rule of thumb often and roughly supposition, especially inevitable low temperature setting excessively, caused the surprising waste of the energy: one, common split-type air conditioner is to use the return air inlet temperature to survey and control the start and stop of compressor of air conditioner, reach the refrigeration purpose, but, because the distribution that the indoor object of laying layout and normal domestic use and commercialization of the interior rack equipment of machine room mainly occupy around the body of wall is different fully, all be in the central authorities in room, cause the not smooth of air-flow circulation, bring the inequality of Temperature Distribution, the temperature of air-conditioning return air inlet can not the real embodiment environment temperature and the temperature of cooled equipment, indoor temperature distribution inhomogeneous brings the not in place and inaccurate of desired temperature, two, because the design selection of air conditioner in machine room all is to calculate according to maximum cooling load, need satisfy the cold and hot exchange of extreme weather (heat), the general configuration bigger than normal of its refrigerating capacity, leave certain surplus capacity, compressor is intermittent duty in the ordinary course of things, but, because the time delay of air-conditioning instruction, bring the unnecessary prolongation of cooling time, the waste that causes electric energy to use, three, because artificial low temperature setting, make air-conditioning be in unnecessary refrigerating operaton state for a long time, cause artificial waste, reason in sum, cause the excessive refrigeration of air conditioner in machine room, produced a large amount of energy wastes, use the energy as required in order to satisfy, being badly in need of a kind of the employing with the temperature of refrigeration object surveys, rather than survey the operation of controlling compressor of air conditioner with the return air temperature of Natural Circulation, pass through technique for temperature compensation, contain the meaningless work of compressor that artificial low temperature setting brings, thereby reach the needs that energy-conservation operation control system satisfies people's calculator room equipment refrigeration.
Summary of the invention
The objective of the invention is to develop a kind of addressing the above problem, simple in structure, convenient suitable, the machine room air-conditioning energy-saving operation control system of good energy-conserving effect.
The technical scheme that the present invention solves its problem is:
The present invention is mainly by main control system, temperature-compensating box and temperature sensor are formed, it is characterized in that: the temperature-compensating box is connected with main control system by data wire with temperature sensor, form complete control system, wherein, main control system comprises: the temperature setting module, the hygroscopy module, difference contrast module, difference judge module and compensation output module, temperature sensor is arranged on needs the refrigeration plant place, strict is sensing with the destination object, the control of realization precise dose, the temperature-compensating box adopts refrigeration semiconductor to make, be connected with air-conditioning return air temperature probe, main control system is by the temperature setting module, the hygroscopy module, difference contrast module, difference judge module and compensation output module control temperature-compensating box carry out temperature correction and compensation to its air-conditioning return air temperature between in due course, in time impose influence of temperature variation, opening of control and adjustment compressor of air conditioner, stop transport and go, main control system carries out ceiling temperature and lower limit temperature setting, when the temperature of need refrigeration plant is higher than the ceiling temperature of setting, the cooling of temperature-compensating box no power, make the compressor operate as normal, when the temperature of need refrigeration plant is lower than the lower limit temperature of setting, temperature-compensating box energising cooling, temperature is lower than the minimum temperature that air-conditioning itself may be provided with, avoid artificial low temperature mistake to be provided with, when temperature is between the bound temperature of setting, the compensation box is interrupted energising, reach the purpose of timely reduction compressor time delay operation, the temperature-compensating time of temperature-compensating box draws with detecting temperature and contrast and judgement that temperature is set.
The bound temperature segment value of setting on temperature value that detects by the external temperature sensor and the main control system compares, when being in different temperature values, main control system control temperature-compensating box carries out suitable and real-time temperature-compensating to the air-conditioning return air temperature, thereby realizes: fully low temp compensating, intermittently low temp compensating and the state that do not have a low temp compensating controls compressor of air conditioner indirectly and are in: do not move, intermittent duty and the complete purpose of normally moving.
The present invention has following advantage:
1, via enforcement of the present invention, do not destroy the seal of machine room, do not change the control circuit of air-conditioning yet, carry out the intelligent decision of cryogenic temperature value and carry out the compensation correction of judging temperature value, just can realize the precise monitoring of computer room temperature and the optimal control of compressor of air conditioner operation, avoid artificial low temperature setting, to air-conditioning without any influence, also without any potential safety hazard, simple and easy to do to calculator room equipment, energy-saving effect is obvious.
