Abstract
A phase changing energy storage air conditioner for a communication machine room comprises an indoor unit and an outdoor refrigerating machine. The outdoor refrigerating machine comprises a condenser, a compressor and a tube-type heat exchanger. The phase changing energy storage air conditioner is characterized in that a plate type heat exchanger, a controller and a phase changing energy storage tank made of phase changing materials are additionally arranged inside the indoor unit, a temperature collector is arranged inside the plate type heat exchanger and is connected with the input end of the controller, and the output end of the controller is connected with the compressor. The indoor temperature can be controlled through exchanging between cold in the natural environment and a cold source of day and night temperature difference in the natural environment and the latent heat of the phase changing materials. Compared with a common air conditioner, the phase changing energy storage air conditioner has the advantages that the energy efficiency ratio of the system is greatly improved, electric energy is saved, the electricity saving rate is more than 30%, the times of starting and stopping of the compressor are reduced, the operation time is shortened, the comprehensive energy efficiency ratio is greatly improved, and the service life is greatly prolonged.
Description
Technical field
The utility model belongs to technical field of electric appliances, relates to a kind of used in communication machine room aircondition, and particularly a kind of have a phase-changing energy-storing case aircondition.
Background technology
The refrigeration modes that existing air-conditioning generally adopts compressor to be combined with condenser, compressor is by the liquid freon of the freon boil down to HTHP of gaseous state, then delivering to after condenser heat radiation the liquid freon that becomes medium temperature and medium pressure, is hot blast so off-premises station produces by boasting.Liquid freon, through capillary, enters evaporimeter, and space increases suddenly, pressure reduces, and liquid freon will be vaporized, and absorbs a large amount of heats, evaporimeter will turn cold, and the fan of indoor set is blown over indoor air from evaporimeter, so indoor set produces by boasting, is exactly cold wind.But in communications equipment room, because the communication equipment electric power is large, heat radiation is large, and variations in temperature is larger, and compressor needs continuous batch (-type) to start, and starts frequency higher, affects service life.
Summary of the invention
The utility model is in order to reduce the startup frequency of compressor, design has increased a kind of device with phase-changing energy-storing case, increase the cycle cooling system with phase-change material, by energy storage materials of phase change heat radiation and compressor cooling cooperation, all be connected to control system of machine room air conditioner, utilize the accumulation of energy characteristic of phase-change material, exchange by the refrigerant with natural environment, provide cold in communications equipment room, enable phase-change material when externally temperature is low and circulate to the communications equipment room internal refrigeration storage.
The technical solution adopted in the utility model is, used in communication machine room phase change energy storage air conditioning device, comprise indoor set and outdoor refrigeration machine, wherein outdoor refrigeration machine comprises condenser, compressor and pipe heat exchanger, key is: increase phase-change accumulation energy tank, plate type heat exchanger and the controller with phase-change material in indoor set, be provided with Temperature sampler in plate type heat exchanger, Temperature sampler is connected with the input of controller, and controller output end is connected with compressor.
The heat exchanger of described indoor phase-change material belongs to plate type heat exchanger.
Described plate type heat exchanger presents vertical formula ripple struction and horizontal type ripple struction.
Also be provided with cross valve in described aircondition, controller is connected with cross valve.
The utility model utilizes the low-temperature receiver of day and night temperature in natural environment and the latent heat of phase-change material, by the Cooling capacity exchanging with natural environment, realizes indoor temperature control.The interchanger of indoor phase-change material is plate heat exchanger, presents vertical formula ripple struction and horizontal type ripple struction and can improve heat exchanger effectiveness.With conventional air-conditioning, compare, can greatly improve the Energy Efficiency Ratio of system, save electric energy, power saving rate is more than 30%, used in communication machine room phase change energy storage air conditioning device can reduce start-stop number of times and the running time of compressor, significantly improves comprehensive energy efficiency ratio and service life.
The accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
1 representation temperature collector, 2 represent controller, and 3 represent cross valve, and 4 represent compressor.
The specific embodiment
Used in communication machine room phase change energy storage air conditioning device, comprise indoor set and outdoor refrigeration machine, wherein outdoor refrigeration machine comprises condenser, compressor 4 and pipe heat exchanger, key is: increase phase-change accumulation energy tank, plate type heat exchanger and the controller 2 with phase-change material in indoor set, be provided with Temperature sampler 1 in plate type heat exchanger, Temperature sampler 1 is connected with the input of controller 2, and controller 2 outputs are connected with compressor 4.
The heat exchanger of described indoor phase-change material belongs to plate type heat exchanger.
Described plate type heat exchanger presents vertical formula ripple struction and horizontal type ripple struction.
Also be provided with cross valve 3 in described aircondition, controller 2 is connected with cross valve 3.
Phase-change material when machine room high temperature, the heat of the room air absorbed by indoor plate type heat exchanger, then to outdoor by outdoor pipe heat exchanger release heat.
During winter low temperature: the phase-changing energy-storing system starts, and phase-change material, as medium, is replaced outdoor natural environment low temperature cold in communications equipment room, reaches the temperature environment of communications equipment room requirement.
When temperature in spring and autumn: at night, the low temperature cold that utilizes natural environment is to the communications equipment room internal cooling time, and phase-change material stores low-temperature receiver; On daytime, during the communications equipment room internal high temperature, indoor phase-change material released cold quantity, realize indoor temperature control requirement, substantially need not open compressor cooling.
During summer high temperature: utilize the accumulation of energy characteristic of phase-change material, when compressor start freezes to the communications equipment room internal cooling, phase-change material stores low-temperature receiver; Phase-change material released cold quantity when compressor quits work, realize indoor temperature control requirement.Improve the compression mechanism cold efficiency, reduce the number of starts and the running time of compressor simultaneously.
