According to structure described above, below the course of work of many refrigeration circulating air conditioners unit of the integrated spray cooling energy-saving function of the present embodiment is described with reference to the accompanying drawings:
As shown in Figure 1, a1 represents the return air of evaporimeter, and a2 represents the air-supply of evaporimeter; B1 represents the air intake of condenser, and b2 represents the air draft of condenser.
This system has three kinds of kind of refrigeration cycle, is referred to as: compression refrigeration circulation, refrigerated medium pump kind of refrigeration cycle, cold-producing medium natural flow kind of refrigeration cycle.
First, refrigerated medium pump kind of refrigeration cycle and cold-producing medium natural flow cool cycles only just can be enabled during lower than indoor temperature at outdoor wet-bulb temperature.And compressor cooling circulates under any outdoor temperature condition and can enable, its conditions for use is: although refrigerated medium pump kind of refrigeration cycle and cold-producing medium natural flow kind of refrigeration cycle are unavailable or available, when refrigerating capacity is not enough.In addition, refrigerated medium pump kind of refrigeration cycle and cold-producing medium natural flow kind of refrigeration cycle and compressor cooling circulation can not be worked simultaneously.
For example, when compression refrigeration conditions being possessed (: the refrigerating capacity deficiency of refrigerated medium pump kind of refrigeration cycle and cold-producing medium natural flow refrigeration, evaporimeter EAT are higher than desired temperature), compression refrigeration startup work.During work, first close described refrigerated medium pump C1, described control valve C3 and the 3rd control valve D1, open described control valve C4, compressor A1.Compressor A1 shortens high pressure, high temperature refrigerant gas into low-temperature low-pressure refrigerant vapour pressure in outdoor location A, and by the second pipeline 12, high-temperature high-pressure refrigerant gas is sent to described condenser A2, high-temperature high-pressure refrigerant in described condenser A2 is toward outdoor heat extraction and be condensed into high temperature high pressure liquid, and be stored in described reservoir C2 liquid phase region C21, now, open described spray cooling energy-saving module, air intake place atomized water spray to described condenser, reduce inlet air temperature of condenser, be conducive to improve the refrigerating efficiency of described compressor, high temperature high pressure liquid enters described expansion valve A3 by the 3rd pipeline 13, pressure declines rapidly, some flash steams produce, reduced the temperature of remaining liq, low-temp low-pressure liquid gas mix refrigerant enters evaporimeter B1 by the 4th pipeline 14, while evaporating in evaporimeter B1, from room air, absorb heat and flash to gas, by the first pipeline 11, enter described compressor A1, and so forth, form continuous compression refrigeration circulation.
For example, when refrigerated medium pump kind of refrigeration cycle conditions being possessed (: outdoor wet-bulb temperature lower than evaporimeter EAT and indoor temperature higher than needed temperature), open refrigerated medium pump cooling recirculation system and coordinate described spray cooling energy-saving module: during work, first close the second control valve C4 and compressor A1, the 3rd control valve D1 and expansion valve A3, open the first control valve C3 and refrigerated medium pump C1.The effect of refrigerated medium pump C1 is the resistance that overcomes refrigerant tubing, realizes flowing of cold-producing medium.Whole cyclic process is with refrigerated medium pump, to promote the pressure of refrigerant liquid, the liquid refrigerant of rising pressure enters the evaporimeter B1 in indoor set B by the 4th pipeline 14, in evaporimeter B1 after evaporation and heat-exchange, utilize the power of heat power and refrigerated medium pump, make refrigerant vapour via the first pipeline 11, the first check-valves C5 on compressor bypass pipeline 16 and compressor bypass pipeline and the second pipeline 12 enter in described condenser A2, now, the mating reaction of described spray cooling energy-saving module, its nozzle is towards the air intake place of described condenser sustained firing water smoke, condenser air intake place is lowered the temperature, increased the difference of evaporimeter EAT and inlet air temperature of condenser, strengthened condensation effect, like this, in condenser A2, refrigerant vapour is condensed into liquid, then via reservoir C2, the first control valve C3 enters the entrance of described refrigerated medium pump C1 again, and so forth, form continuous refrigerated medium pump cool cycles.
Whether described spray cooling energy-saving module carries out spraying work, by control system by the difference of outdoor wet-bulb temperature and evaporimeter EAT and according to refrigerating efficiency with refrigeration reliability etc. because of usually judgement.This energy-saving module is not worked during higher than evaporimeter EAT at outdoor wet-bulb temperature.When outdoor wet-bulb temperature is during lower than evaporimeter EAT, according to the needs of refrigerating efficiency and reliability, open: if do not open spraying, also can not have and meet necessary refrigerating efficiency or open spraying can play side effect time, the work of the energy-saving module that just stops spraying.
When cold-producing medium natural flow kind of refrigeration cycle conditions being possessed (for example: outdoor wet-bulb temperature lower than evaporimeter EAT and indoor temperature higher than needed temperature, outdoor location higher than indoor set), can also adopt natural flow cooling recirculation system: first, the condition that this nature cooling recirculation system is implemented is the installation site height higher than indoor set B by the installation site height of outdoor location A, because only have in this case, cold-producing medium just can rely on himself gravity and heat power to realize nature cool cycles.During work, first close the first control valve C3 and refrigerated medium pump C1, the second control valve C4 and compressor A1, open the 3rd control valve D1.Liquid refrigerant enters described the 3rd control valve D1 via described expansion valve the second bypass line 17, because outdoor location A installation site is higher than indoor set B installation site height, therefore, liquid refrigerant enters the evaporimeter B1 in indoor set B according to self gravitation by the 4th pipeline 14, in evaporimeter B1, liquid refrigerant evaporation endothermic becomes refrigerant vapour, then by the first pipeline 11, the first check-valves C5 on compressor bypass pipeline 16 and compressor bypass pipeline 16, the second pipeline enters the entrance of described condenser A2, now, the mating reaction of described spray cooling energy-saving module, its nozzle is towards the air intake place of described condenser sustained firing water smoke, condenser air intake place is lowered the temperature, in condenser A2, refrigerant vapour condensing heat-exchange becomes refrigerant liquid gas mixture, liquid vapour mixture stores liquid refrigerant by reservoir, liquid refrigerant enters described the 3rd control valve D1 again by the 3rd pipeline 13 being communicated with reservoir C2 liquid phase region C21, and so forth, form continuous natural flow cool cycles.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments (for example: while having had high service system in whole data center, cancel water intaking valve E2, filter E3 and water pump E4, sprayer unit is directly introduced external high pressure water).And the apparent variation of being extended out thus or change are still among protection domain of the present utility model.
