For reaching above-mentioned purpose, the present invention is achieved through the following technical solutions.
The machine room energy-saving cooling system, its structure is as follows: compressor, condenser of connecting and evaporimeter with compressor, between condenser and evaporimeter, be provided with gas-liquid separator, between gas-liquid separator and evaporimeter, be serially connected with first magnetic valve and throttling arrangement, compressor is in parallel with second magnetic valve, and first magnetic valve and throttling arrangement are in parallel with the 3rd magnetic valve.
Described throttling arrangement is a heating power expansion valve.
The level height of described condenser is than the level height height of evaporimeter.
Described the 3rd magnetic valve and auxiliary circulating pump are connected in series.
Described auxiliary circulating pump is air pump or water pump.
The control method of machine room energy-saving cooling system, when outdoor temperature was higher than indoor temperature, second magnetic valve, the 3rd magnetic valve and auxiliary circulating pump were closed, and first magnetic valve is opened, compressor start work; When outdoor temperature is lower than indoor temperature and indoor when needing refrigeration, first closed electromagnetic valve, compressor does not start, and starts second magnetic valve, the 3rd magnetic valve carries out energy-conservation refrigeration.
Close second magnetic valve, the 3rd magnetic valve when reaching the indoor temperature setting value after described startup second magnetic valve, the 3rd magnetic valve and auxiliary circulating pump freeze.
Describedly freeze to reach the indoor temperature setting value time, start compressor cooling when starting second magnetic valve, the 3rd magnetic valve.
Described temperature after starting second magnetic valve, the 3rd magnetic valve and freezing is higher than indoor temperature setting value 2 when spending, and starts compressor cooling.
Advantage of the present invention and effect are as follows:
When outdoor temperature is lower than indoor temperature, starting energy-conservation refrigeration, the interior refrigerant heats of evaporimeter this moment becomes gas and rises to outdoor condenser, because the temperature of outdoor condenser is lower, the refrigerant loses heat of gaseous state becomes liquid refrigerant, and descend and to flow back to indoor evaporimeter and form a kind of kinetic energy, reach heat radiation and purpose of energy saving.System of the present invention moves more power saving, has effectively saved electric energy, and has reduced the time of operation of air conditioner, has prolonged the service life of air-conditioning.

Among the figure: 1, compressor; 2, condenser; 3, evaporimeter; 4, first magnetic valve; 6, gas-liquid separator; 8, throttling arrangement; 9, second magnetic valve; 10, the 3rd magnetic valve; 11, auxiliary circulating pump.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Embodiment 1:
As shown in Figure 1, machine room energy-saving cooling system of the present invention, constitute by following structure: compressor 1, condenser 2 of connecting with compressor 1 and evaporimeter 3 are provided with gas-liquid separator 6 between condenser 2 and evaporimeter 3, be in series with first magnetic valve 4 and throttling arrangement 8 between gas-liquid separator 6 and evaporimeter 3 successively, compressor 1 is in parallel with second magnetic valve 9, at the two ends of first magnetic valve 4 and throttling arrangement 8 the 3rd magnetic valve 10 in parallel, condenser 2 is located at outdoor, and evaporimeter 3 is located at indoor.
Refrigerant in described condenser and the evaporimeter can be under the situation that compressor does not start cycle heat exchange automatically.Refrigerant in evaporimeter and the condenser flows to and will meet the trend that vapour-liquid changes, otherwise just need install auxiliary circulating pump additional.Described the 3rd magnetic valve 10 is connected in series with auxiliary circulating pump 11.
Above-mentioned auxiliary circulating pump 11 is air pump or water pump.Throttling arrangement 8 is a heating power expansion valve.The level height of condenser 2 is than the level height height of evaporimeter 3.
The control method of machine room energy-saving cooling system is made of following step: when outdoor temperature was higher than indoor temperature, second magnetic valve 9, the 3rd magnetic valve 10 were closed, and first magnetic valve 4 is opened, and compressor 1 starts system's operate as normal; When outdoor temperature is lower than indoor temperature and indoor when needing refrigeration, first magnetic valve 4 cuts out, and compressor 1 cuts out, and starts second magnetic valve 9, the 3rd magnetic valve 10 freezes.
Embodiment 2:
When starting to reach after second magnetic valve 9, the 3rd magnetic valve 10 and auxiliary circulating pump 11 freeze, embodiment 1 closes second magnetic valve 9, the 3rd magnetic valve 10 when indoor low temperature sets value.Start second magnetic valve 9, the 3rd magnetic valve 10 and freeze in the time of to reach the desired temperature that heat radiation requires, start compressor 1 refrigeration.Start second magnetic valve 9, the 3rd magnetic valve 10 and freeze in the time of reaching the desired temperature that heat radiation requires, close all magnetic valves, compressor and circulating pump, refrigeration system quits work.When raising once more, indoor temperature starts energy-conserving refrigeration system once more.
Be specially: the indoor temperature setting value is 26 degree, can not reach 26 when spending and surpass 28 degree when starting second magnetic valve 9, the 3rd magnetic valve 10 and the auxiliary circulating pump 11 indoor temperature in back of freezing, (when energy-conservation refrigeration does not reach the cold of room requirement) so just starts compressor 1 and freezes.Reach preferential when starting once more behind the design temperature and start energy-conservation refrigeration; Freeze can reach the desired temperature that heat radiation requires the time when starting second magnetic valve 9, the 3rd magnetic valve 10 and auxiliary circulating pump 11, close all magnetic valves, compressor and circulating pump, refrigeration system quits work.When raising once more, indoor temperature starts energy-conserving refrigeration system once more.
Described auxiliary circulating pump 11 can not use circulating pump under desirable mounting condition, only do not use when reaching mounting condition, or auxiliary refrigerant circulates, to reach the purpose of refrigerated energy-saving.
Embodiment 3:
When embodiment 2 starts temperature after second magnetic valve 9, the 3rd magnetic valve 10 and auxiliary circulating pump 11 freeze and is higher than indoor temperature setting value 2 and spends, start compressor 1 refrigeration.Other is with embodiment 2.Setting value can be set in original controller of system.
