Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of compact conformation, when environment temperature-25 ℃ ~+38 ℃, air conditioner all can normally carry out the cooling condition operation, the requirement of the heat that satisfied expeling cabin internal heat generation equipment gives out, the ultralow temperature outdoor machine of air-conditioner that operating ambient temperature range is wide.
The technical solution adopted in the utility model is: a kind of ultralow temperature outdoor machine of air-conditioner, its technical characterstic is to comprise refrigeration compressor, magnetic valve more than one, air-cooled condenser, variable-frequency motor, cooling fan, check valve, check (non-return) valve, dehydrator, refrigeration compressor one end connects indoor set, be connected with side by side magnetic valve and a check (non-return) valve more than two on the other end, air-cooled condenser is that two above condensers combine side by side, magnetic valve more than two connects respectively two above condensers, two above condensers connect reservoir through check valve respectively, check (non-return) valve connects reservoir, and reservoir drying device connects indoor set.
Further, described refrigeration compressor is provided with Pressure gauge, dual-pressure controller and pressure sensor.
Again further, described refrigeration compressor is provided with the crankcase heating cabinet.
During the work of ultralow temperature outdoor machine of air-conditioner, the low-pressure gas of refrigerant sucks from indoor machine evaporation and is collapsed into high-temperature gas through refrigeration compressor, enter in the condenser, after walking heat, the cooling-air salband make refrigerant become highly pressurised liquid, behind dry filter, become low pressure liquid by expansion valve control expenditure and pressure, enter in the indoor machine evaporation pipe by evaporation tube and fin and evaporimeter outside air and carry out heat exchange, become low-pressure gas after the refrigerant heat absorption, reenter the refrigeration compressor compression and circulate.The air heat release cooling behind the evaporimeter of then flowing through blows out off-premises station by centrifugal blower, circulates in air conditioned cabin.
Adopt above technical scheme, the beneficial effect that the utility model reaches is: by control valve and check (non-return) valve acting in conjunction, adjusting is by the refrigerant amount of air-cooled condenser, and the rotating speed of regulating the frequency conversion cooling blower to electric control box by pressure sensor transmission pressure information changes cooling air quantity, thereby adjust the condensing pressure of air-conditioning system, reach the system pressure balance and stability; Can regulate the condenser number that air-cooled condenser participates in cooling by magnetic valve and check valve acting in conjunction, cooperate variable-frequency motor to regulate cooling fan, satisfy corresponding air-cooled that the wind adjustable huyashi-chuuka (cold chinese-style noodles) amasss, the cooling requirement that changes to adapt to car and boat different external environment conditions of living in and internal environment, can satisfy refrigeration use under the global environment, the scope of application is wide.
Description of drawings
Fig. 1 is that the utility model uses the example structure schematic diagram.
Among the figure: off-premises station 1, off-premises station 2, electric control box 3, centrifugal blower 4, evaporimeter 5, connecting line 6, refrigeration compressor 7, crankcase heating cabinet 8, Pressure gauge 9, dual-pressure controller 10, pressure sensor 11, safety valve 12, magnetic valve 13, air-cooled condenser 14, condenser 141, variable-frequency motor 15, cooling fan 16, check valve 17, control valve 18, reservoir 19, check (non-return) valve 20, device for drying and filtering 21, expansion valve 22.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of ultralow temperature outdoor machine of air-conditioner shown in Figure 1 cooperates the use structural representation of indoor set, comprise off-premises station 1, off-premises station 2 and electric control box 3, evaporimeter 5 gas outlets of off-premises station 1 are connected to the evaporimeter inlet through refrigeration compressor 7, air-cooled condenser 14, reservoir 19, device for drying and filtering 21, the expansion valve 22 that connecting line 6 connects off-premises station successively, are provided with the centrifugal blower 4 between corresponding evaporimeter and air outlet in the off-premises station; Electric control box 3 is arranged in the off-premises station 2, be provided with the cooling fan 16 of corresponding air-cooled condenser in the off-premises station 2, refrigeration compressor is connected with centrifugal blower and is connected electric control box 3, air-cooled condenser 14 is that two above condensers 141 combine side by side, arbitrary or all condenser inlet all are equipped with magnetic valve 13, and arbitrary or all condensator outlets all are equipped with check valve 17; Cooling fan 16 is by variable-frequency motor 15 control connections, and magnetic valve, variable-frequency motor all connect electric control box; Refrigeration compressor is provided with Pressure gauge 9, dual-pressure controller 10 and the pressure sensor 11 that all is connected in electric control box; Be provided with check (non-return) valve 20 between refrigeration compressor and the reservoir; The merging of condensator outlet check valve is connected to reservoir by control valve 18; Refrigeration compressor connects the condenser of air-cooled condenser through safety valve 12, magnetic valve; Refrigeration compressor is provided with crankcase heating cabinet 8.
During the work of ultralow temperature outdoor machine of air-conditioner, the low-pressure gas of refrigerant sucks from evaporimeter and is collapsed into high-temperature gas through refrigeration compressor, enter in the condenser, after walking heat, the cooling-air salband make refrigerant become highly pressurised liquid, behind dry filter, become low pressure liquid by expansion valve control expenditure and pressure, enter in the evaporator tube by evaporation tube and fin and evaporimeter outside air and carry out heat exchange, become low-pressure gas after the refrigerant heat absorption, reenter the refrigeration compressor compression and circulate.The air heat release cooling behind the evaporimeter of then flowing through blows out off-premises station by centrifugal blower, circulates in air conditioned cabin.Externally temperature is crossed low or off-premises station heat exchange amount demand when reducing, participate in by reducing air-cooled condenser cooling the condenser number, reduce variable-frequency motor rotating speed, directly supply with high-temperature gas from refrigeration compressor to reservoir by check (non-return) valve, reducing the evaporimeter heat-energy transducer needs, and realizes the condensing heat-exchange of low temperature or ultralow temperature.
