The specific embodiment
Below with reference to accompanying drawing, use following embodiment to be further elaborated the utility model.
As shown in Figure 1, one multifunction refrigeration air conditioner unit in parallel described in the present embodiment, it comprises the vaporising device 1, compression set 2, the condensing unit 3 that are linked to be successively closed circuit by pipeline, and be located at the expansion valve 4 between described condensing unit 3 and described vaporising device 1, also comprise and being located between described condensing unit 3 and described vaporising device 1, and in parallel with described expansion valve 4 for naturally cooling bypass solenoid valve 5, and be arranged on the high-order air-out apparatus 6 of evaporimeter of the port of export of described vaporising device 1; Described compression set 2 comprises multiple parallel with one another and compressors that power is different.In the present embodiment, when outdoor temperature is during lower than indoor temperature, can open described bypass solenoid valve, and strengthen the natural cooling effect of described vaporising device by the high-order gas-returning devices of described evaporimeter, if desired, can also open described compressor and strengthen the cooling ability of nature, it is cooling that the air-conditioning unit of this structure can not only carry out machinery like this, and in outdoor temperature during lower than indoor temperature, can also carry out nature cooling, realize low temperature nature cooling and energy conserving function.
In the present embodiment, described vaporising device 1 comprises evaporimeter 11 and evaporator fan 12, and described condensing unit 3 comprises condenser 31 and condenser fan 32.As preferred embodiment, the high-order gas-returning devices 6 of described evaporimeter is made as the elbow pipeline being arranged between described vaporising device 1 and described compression set 2, described elbow pipeline peak 61 peaks higher than described evaporimeter 11.The high-order air-out apparatus 6 of described like this evaporimeter can make described evaporimeter 11 in full liquid status, thereby at utmost brings into play the cooling heat absorption capacity of described evaporimeter 11.
Further, if in installation process, can guarantee that the installation site of described condensing unit 3 is higher than the installation site of described evaporimeter 11, the bypass line that be provided with by-passing valve 7 in parallel with described compression set 2 can also be set, like this when outdoor temperature is during lower than indoor temperature, can make cryogen realize nature by described bypass solenoid valve 5 and described bypass line 7 cooling, enough thick at pipeline diameter, be in the situation that pipe resistance is enough little, generally do not need to open described compression set 2, like this, natural cooling and energy conserving is most effective.But, due to the existence of pipe-line system resistance, sometimes only rely on the mode of opening bypass solenoid valve, its maximum natural cooling capacity is restricted, now, close described bypass line 7, the mode of opening one to two or one to three compressor improves free cooling refrigeration ability.It is cooling that the air-conditioning unit like this with this structure can not only carry out machinery, and can also be in outdoor temperature during lower than indoor temperature, in from the less temperature difference of indoor and outdoor to larger temperature range, all can carry out the natural cooling and energy conserving operation of greater efficiency, and realize equally the adjusting of multi-level refrigerating capacity, make free cooling refrigeration ability and load exact matching.
If it is unavailable that the natural type of cooling of described bypass line 7 lower than the installation site of evaporimeter, is opened in the installation site of condenser.Now, only need to open as required one to two or one to three compressor, can realize nature cooling.
As preferred embodiment, in the present embodiment, the number of described compressor in parallel is made as three, the power ratio of three described compressors is 3:2:1, and the outlet of each described compressor is provided with a check-valves 8, like this in the time of one of them or two described compressor operating, can not make the motion action of other described compressor, certainly, the number of described compressor in parallel can arrange arbitrarily according to actual conditions, and described in each, power of compressor also can arrange arbitrarily as required.
On the basis of above-described embodiment, described vaporising device 1 comprises evaporimeter 11 and evaporator fan 12, and described condensing unit 3 comprises condenser 31 and condenser fan 32, and the port of export of described condenser 31 is also provided with reservoir.
In the present embodiment, when outdoor temperature is during lower than indoor temperature, open described bypass solenoid valve 5 and described bypass line 7 and realize nature cooling and energy conserving; In the time that outdoor temperature is more lower than indoor temperature, due to refrigeration pipe resistance, while making the refrigerant flow of this natural type of cooling be difficult to promote, just close described bypass line 7, open described compressor circulating mass of refrigerant is promoted, strengthen free cooling refrigeration ability.The combination of the compressor by one to three different ability, realizes multiple different natural cooling capacity and the combination of efficiency, make a whole set of Cooling System from indoor/outdoor temperature-difference hour when larger, have higher refrigerating efficiency.Compared with the Cooling System of existing employing refrigerated medium pump, natural cooling effectiveness while having promoted the less temperature difference of indoor and outdoor, because in existing refrigerated medium pump system, refrigerated medium pump must be opened, and not speed governing, does not adopt many parallels connection of pumps yet, so, at indoor/outdoor temperature-difference hour, the natural type of cooling efficiency of opening refrigerated medium pump is lower.
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 without also giving exhaustive to all embodiments.And the apparent variation of being extended out thus or variation are still among the protection domain in the invention.
