Description
Technical field
The present invention is a kind of air-conditioner that is used for machine room, belongs to the improvement technology of the air-conditioner that is used for machine room.
Background technology
Development along with the information industry; The quantity of communications equipment room is also in rapid increase; And the normal operation that will keep machine room must have refrigeration plant to keep the environmental requirement of machine room; According to existing statistics; The energy consumption for cooling of machine room occupies the energy consumption of whole equipment room system nearly 40%, and the refrigerated energy-saving of machine room seems more and more important.Utilize having that the cold of outside environment realizes freezing in the power-saving technology of existing machine room refrigeration: ethylene glycol cool off and the new wind of direct introducing naturally.Wherein ethylene glycol nature cooling system need increase by a cover ethylene glycol heat exchange coil, has increased the load of indoor fan, and the annual energy consumption of blower fan increases, and has offset the part energy-saving effect; Directly introduce new wind; Major defect is that introducing can cause the equipment condensation when low when outdoor temperature is crossed, and must filter new wind in addition, and filter needs the regular maintenance of professional person; And whether the quality of filtering the back air meet the demands and be difficult to judge, may erode to equipment in the machine room.
Summary of the invention
The purpose that the present invention is is to consider the problems referred to above and a kind of not only good energy-conserving effect is provided, can avoid original technology to have the air-conditioner that is used for machine room of defective simultaneously.
Technical scheme of the present invention is: a kind of air-conditioner that is used for machine room; Include compressor; First one-way control valve; Condenser; Liquid reservoir; The first throttle device; Evaporimeter; On-off control valve; Wherein the outlet of compressor is connected to the inlet of condenser through first one-way control valve; The outlet of condenser is connected to the inlet of liquid reservoir; The outlet of liquid reservoir is connected to the inlet of evaporimeter through the first throttle device; The outlet of evaporimeter is connected to the on-off control valve inlet; The on-off control valve outlet is connected to the inlet of compressor; It is characterized in that also comprising the liquid pump; Second throttling arrangement and second one-way control valve; Wherein liquid pump and the two ends that are attempted by the first throttle device after second throttling arrangement is connected in series; The inlet of liquid pump is connected with the outlet of liquid reservoir; Outlet is connected with the inlet of second throttling arrangement; The outlet of second throttling arrangement is connected with the inlet of evaporimeter; The inlet of second one-way control valve is connected on the pipeline between evaporimeter and the on-off control valve, and outlet is connected on the pipeline between first one-way control valve and the condenser.
Said on-off control valve is two disconnected all control valves.
Said on-off control valve is the threeway on-off control valve, and threeway on-off control valve inlet connects the outlet of evaporimeter, and an outlet connects the inlet of compressor, and another outlet connects the inlet of second one-way control valve.
Said first one-way control valve and second one-way control valve are check valve.
The present invention adopts two kinds of refrigerating operaton patterns, and during conventional refrigerating operaton, the liquid pump cuts out, and compressor and starting is carried out kind of refrigeration cycle; When the environment temperature of condenser side is lower than the vaporizer side environment temperature; Open the liquid pump; Close compressor; Carry out cooling cycle system through the liquid pump; Since the electric energy that the electric energy that the running of liquid pump consumes consumes much smaller than compressor operating, thus reach energy-saving effect, and the while cools off naturally with original ethylene glycol and directly introduces new wind facies ratio; This power save mode can not increase the load of blower fan, and has avoided the condensation and the air quality problems of new wind.
The specific embodiment
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation of the embodiment of the invention 2.
Below in conjunction with accompanying drawing and embodiment the present invention is described further
Embodiment 1:
As shown in Figure 1; The present invention is used for the air-conditioner of machine room; Include compressor 1; First one-way control valve 2; Condenser 3; Liquid reservoir 4; First throttle device 5; Evaporimeter 8; On-off control valve 9; Liquid pump 6; Second throttling arrangement 7 and second one-way control valve 10; Wherein the outlet of compressor 1 is connected to the inlet of condenser 3 through first one-way control valve 2; The outlet of condenser 3 is connected to the inlet of liquid reservoir 4; The outlet of liquid reservoir 4 is connected to the inlet of evaporimeter 8 through first throttle device 5; The outlet of evaporimeter 8 is connected to the inlet of on-off control valve 9; The outlet of on-off control valve 9 is connected to the inlet of compressor 1; Liquid pump 6 and the two ends that are attempted by first throttle device 5 after second throttling arrangement 7 is connected in series; The inlet of its liquid pump 6 is connected with the outlet of liquid reservoir 4; Outlet is connected with the inlet of second throttling arrangement 7; The outlet of second throttling arrangement 7 is connected with the inlet of evaporimeter 8; The inlet of second one-way control valve 10 is connected on the pipeline between evaporimeter 8 and the on-off control valve 9, and outlet is connected on the pipeline between first one-way control valve 2 and the condenser 3.
In the present embodiment, said on-off control valve 9 is two disconnected all control valves.Said first one-way control valve 2, second one-way control valve 10 are check valve.
When the present invention works; Under the conventional refrigerating operaton pattern; Refrigerant through compressor 1 compression after the condensation in the condenser 3 of first one-way control valve 2; Evaporation in liquid reservoir 4, the laggard evaporimeter 8 of first throttle device 5 throttlings then; Through 9 times compressors of on-off control valve, so circulation realizes conventional refrigeration again.Under energy conservation model; Refrigerant provides power through liquid pump 6, after 7 throttlings of second throttling arrangement, in evaporimeter 8, evaporates, and arrives condenser 3 condensations through second one-way control valve 10 then; Get back to the liquid pump through liquid reservoir 4 again, so circulation realizes the energy saver mode refrigeration.Because the energy consumption of liquid pump is much smaller than compressor, thereby reach energy-saving effect.
