Strict demand to air purity can not be reduced in transition season as common air-conditioning using the method for increasing fresh air
Operation energy consumption.Even in winter, because a large amount of heat dissipations of equipment, computer room are also required to freeze.
The special of refrigerating operaton is required throughout the year to the temperature of environment, the exact requirements of humidity and air conditioner in machine room
Property, so that air conditioner in machine room has the specificity different from common air-conditioning in use.Air conditioner in machine room requires at all seasons
Refrigeration, even if in winter.
It would therefore be highly desirable to solve above-mentioned technical problem.
Summary of the invention
Goal of the invention: the object of the present invention is to provide one kind can use in winter with transition season outdoor natural cooling source into
Row refrigeration, is effectively reduced the energy-saving machine room air-conditioner set of energy consumption and operating cost.
Technical solution: in order to achieve the above object, the invention discloses a kind of energy-saving machine room air-conditioner sets, comprising:
First circulation system, including be sequentially connected end to end in turn by pipeline evaporator, refrigeration compressor, air-cooled condenser and
Expansion valve；
Second circulation system, including indoor surface air cooler, the refrigerating medium circulating pump, outdoor being sequentially connected end to end in turn by pipeline
Side finned heat exchanger；
Control system, when outdoor environment temperature is higher than setting room conditioning temperature, which opens first circulation
System realizes the control to room temperature；When outdoor environment temperature is lower than 10 DEG C of room conditioning temperature of setting or more, the control
System opens control of the second circulation system realization to room temperature.
Wherein, the air side outlet of the indoor surface air cooler is connected by flange with the air side-entrance of evaporator,
And the windward side length and width of indoor surface air cooler are identical with the windward side length and width of evaporator.
Preferably, the evaporator side is equipped with indoor circulation blower, and indoor surface air cooler and evaporator share the room
Interior circulating fan.
Furthermore the air-cooled condenser side is equipped with condensation fan.
Preferably, outside finned heat exchanger side is equipped with cooling blower.
Further, the evaporator, refrigeration compressor, air-cooled condenser, expansion valve and indoor surface air cooler are arranged in room
Interior, the refrigerating medium circulating pump and outside finned heat exchanger are arranged in outdoor.
The utility model has the advantages that compared with prior art, the present invention has following remarkable advantage: energy-saving machine room air conditioner of the present invention
Group does not use electric driven compression and freezes with transition season using the realization indoor cooling of computer room of outdoor natural cold source in winter,
Relative to common computer-room air conditioning system, in winter and transition season, operating cost can be saved, reduce operating cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Technical solution of the present invention is described further with reference to the accompanying drawing.
As shown in Figure 1, a kind of energy-saving machine room air-conditioner set of the present invention, comprising: first circulation system, including pass through pipeline
Evaporator 1, refrigeration compressor 2, air-cooled condenser 3 and the expansion valve 4 being sequentially connected end to end in turn；Second circulation system, including pass through
Indoor surface air cooler 5 that pipeline is sequentially connected end to end in turn, refrigerating medium circulating pump 6, outside finned heat exchanger 7；Control system, when
When outdoor environment temperature is higher than setting room conditioning temperature, which opens first circulation system and realizes to room temperature
Control；When outdoor environment temperature is lower than 10 DEG C of room conditioning temperature of setting or more, which opens second circulation system
Realize the control to room temperature.
Evaporator 1, refrigeration compressor 2, air-cooled condenser 3, expansion valve 4 and the setting of indoor surface air cooler 5 of the invention exists
The air side outlet of interior, indoor surface air cooler 5 is connected by flange with the air side-entrance of evaporator 1, and indoor table is cold
Device 5 and evaporator 1, air side series connection, make air first flow through indoor surface air cooler 5, are flowing through evaporator 1.Indoor surface air cooler 5
Windward side length and width it is identical with the windward side length and width of evaporator 1.1 side of evaporator is equipped with indoor circulation blower 8, and indoor table
Cooler 5 and evaporator 1 share the indoor circulation blower 8, realize the series connection on air-flow direction.3 side of air-cooled condenser is set
There is condensation fan 9.Refrigerating medium circulating pump 6 and outside finned heat exchanger 7 are arranged in outdoor, outside finned heat exchanger 7
Side is equipped with cooling blower 10.Indoor surface air cooler 5 and outside finned heat exchanger 7 fill second two by piping connection
Alcohol refrigerating medium realizes circulation by refrigerating medium circulating pump 6.
The summer temperature higher time, i.e., when outdoor environment temperature is higher than setting room conditioning temperature, through refrigerant compression
The refrigerant vapour of high temperature and pressure after the compression of machine 2, is condensed into liquid and is subcooled in air-cooled condenser 3, liquid supercooling system
It after expanded 4 expansion throttling of valve of cryogen, is evaporated in evaporator 1, exports cooling capacity, reach refrigeration effect.In winter and outdoor temp
Degree is lower than the transition season of room temperature, i.e., when environment temperature is lower than 10 DEG C of room conditioning temperature of setting or more, compression refrigeration
Circulation does not work, i.e. first circulation system does not work；Second circulation system is enabled, refrigerating medium passes through indoor surface air cooler 5 and room
Interior air exchanges heat, and after refrigerant temperature increases, send through refrigerating medium circulating pump 6 to outside finned heat exchanger 7 and room
Outer air exchanges heat, and makes the reduction of refrigerating medium cooling temperature, then side surface air cooler 5 sent to the room, and then realizes using outdoor natural
Cold source is the purpose of indoor environment cooling, and in the period, energy-saving machine room air-conditioner set does not have to open compressor, is only opened
Refrigerating medium circulating pump reduces system overall energy consumption, reaches energy-efficient effect.
The above examples are only used to illustrate the technical scheme of the present invention rather than restriction technologies scheme.It should be appreciated that this field
Those of ordinary skill without creative work can it is according to the present invention design make many modifications and variations.Therefore, all
Those skilled in the art pass through logic analysis, reasoning or limited reality on the basis of existing technology under this invention's idea
