Abstract
A cold and hot water type precise air conditioning system carries out dehumidification temperature compensation by virtue of heat of hot water made through a multifunctional cold and hot water unit, thus eliminating power consumption caused by electric heating, and achieving the water-saving purpose; water is adopted as a secondary refrigerant, the flow of cold and hot water is controlled by a frequency conversion water pump, thus further precisely controlling the temperature of a room; the system adopts a cold water tank and a hot water tank to carry out coldness storage and heat storage, so that the air conditioning system can not completely rely on the refrigeration system of a host within short time, thus achieving the purpose of discontinuous running and improving the reliability of equipment in a machine room.
Description
Under technical field a kind of be refrigerating medium with water, can accurately control room temperature and humidity, precision air conditioner that can reliability service steady in a long-term.
Background technology increasing communication apparatus machine room occurred along with the develop rapidly of China's telecommunication industry, and these equipment machine rooms are had relatively high expectations to environment temperature and humidity, and the air conditioner in machine room of its humiture can be accurately controlled in general use.Traditional air conditioner in machine room generally with equipment as for indoor, adopt compressor cooling or dehumidifying, employing electrical heating as the temperature-compensating of dehumidifying, adopt humidifier to come humidification.This traditional control mode is used in a large number, but still not enough below existing: adopt electrical heating as temperature-compensating when 1, dehumidifying, the waste electric power resource; 2, at present comparatively ripe invariable frequency compressor refrigeration system to the accuracy control over temperature ability a little less than, and the frequency-changeable compressor system is still immature, is not used widely in the air conditioner in machine room field as yet; 3, when the air-conditioning unit all breaks down, the humiture in the machine room influences the machine room reliability of operation with out of hand.
Summary of the invention: the object of the invention, can solve the problem of electrical heating waste electric energy, guarantee that simultaneously the humiture of machine room is accurately controlled, and can guarantee that the short time still can uninterruptedly guarantee the humiture in the machine room under the situation that main frame breaks down.
The present invention solves the employed technical scheme of its technical problem:
1, adopt Mobyneb hot and cold water unit as main frame, this unit can separate refrigeration water, heat water separately, produce cold water and hot water simultaneously, and this unit eer is high, and when chilled water heated water simultaneously, high energy efficiency ratio can reach more than 7.0;
2, two attemperaters are set, are respectively applied for and store cold water and the hot water that main frame is produced;
3, indoor set is installed in machine room, indoor set is made up of several parts such as cold water fan coil, hot water fan coil, humidifiers;
4, the blower fan of cold water fan coil adopts the adjustable speed blower fan, is used to control the air circulation of chilled water coil, and then control refrigerating capacity and leaving air temp.
5, indoor set hot water or cold water coil pipe respectively and the water pump between the hot and cold water tank adopt the velocity fluctuation pump can control discharge, be used to control hot water or cold water's discharge, and then refrigerating capacity, the heating capacity of control indoor set.
Benefit of the present invention is: because the hot water in the hot water is to produce according to known method recuperation of heat in refrigeration through main frame; Consumed energy not; So carry out temperature-compensating through this hot water, saved the energy that electrical heating consumed, improved the Energy Efficiency Ratio of air-conditioning system greatly; Discharge through variable frequency pump is regulated, and makes the refrigerated medium adjustable heat load of indoor coil, has improved the Temperature and Humidity Control precision; When the main frame refrigeration system broke down, cold and heat through the hot and cold water in the water tank stores still can provide uninterrupted Temperature and Humidity Control, the reliability of the calculator room equipment when having improved air-conditioning unit fault.
Hereinafter combines accompanying drawing that the present invention is further specified.
Accompanying drawing is a systematic schematic diagram of the present invention
Among the figure 1, Mobyneb hot and cold water unit 2, cold water constant speed water pump 3, hot water constant speed water pump 4, cold water water tank 5, hot water 6, cold water velocity fluctuation pump 7, hot water velocity fluctuation pump 8, chilled water coil 9, hot-water coil pipe 10, chilled water coil speed-changing draught fan 11, hot-water coil pipe constant speed blower fan 12, electrode humidifier
Hot and cold water type precision air conditioner system in the specific embodiment accompanying drawing; Form by host machine part, water tank part, interior machine part three parts; Wherein main frame is known Mobyneb hot and cold water unit 1, and this unit can be produced cold water, hot water simultaneously, or produces one of them separately; Water in the cold water water tank 4 circulates between water pump 2 and the main frame through cold water surely frequently; Through the cooling of main frame, the water in the water tank gradually becomes the lower chilled water of temperature, and in like manner the water in the hot water 5 becomes the higher hot water of temperature.
Interior machine has partly comprised chilled water coil 8 and hot-water coil pipe 9; Chilled water coil circulates with the water in the cold water water tank through cold water velocity fluctuation pump 6; Air in the machine room carries out heat exchange through chilled water coil speed-changing draught fan 10 with the cold water in the chilled water coil 8; Make the air cooling, and the moisture in the air is separated out the purpose that reaches cooling and dehumidify.In like manner the air in the machine room carries out heat exchange through hot-water coil pipe speed-changing draught fan 11 with the hot water in the hot-water coil pipe, and air themperature is raise, and reaches the purpose of intensification.
For 6,7 two velocity fluctuation pumps, its rotating speed can be set with the size of the absolute value of the difference of design temperature according to actual temperature in the machine room, and when this value was big, water pump moved in fair speed, when this value hour, water pump is to move than low velocity.So just, greatly reduce the temperature fluctuation in the room, reach the purpose of accurate temperature controlling through the mode of control discharge.
For chilled water coil speed-changing draught fan 10, its rotating speed can be set with the difference size of setting humidity according to actual humidity in the machine room, when this value is big; This blower fan low cruise reduces air quantity, and then improves moisture removal; When this humidity difference is less, the blower fan high-speed cruising, and then reduce moisture removal; To reduce moisture fluctuation, reach the wet purpose of accurate control.
When the main frame refrigeration system breaks down; Main shut-down system; Hot water or cold water's velocity fluctuation pump still continues operation according to former control logic, and two blower fans of indoor coil also still continue operation, utilize the cold and the heat of the water in the hot and cold water tank that the humiture in the machine room is accurately regulated.
