accompanying drawing explanation:
Below in conjunction with drawings and the specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of the preferred embodiment of the utility model.
the specific embodiment:
As shown in Figure 1, a kind of freezing type mould dehumidifier, include the first refrigeration system 2, the second refrigeration system 3 and a pressure fan 11, the first refrigeration system 2 is by the first gas-liquid separator 27, the first compressor 21, the first shell and tube condenser 23, finned cooler 24, the first device for drying and filtering 25, the circulatory system that the first expansion valve 26 and the first finned evaporator 28 are connected in sequence, the second 3 of refrigeration systems are by the second gas-liquid separator 36, the second compressor 31, the second shell and tube condenser 33, the second device for drying and filtering 34, the circulatory system that the second expansion valve 35 and the second finned evaporator 38 are connected in sequence.
The first finned evaporator 28, the second finned evaporator 38, finned cooler 24 and pressure fan 11 are arranged in order on air dewetting passage 1, need a side of first finned evaporator 28 of dehumidified air from air dewetting passage 1 to enter, a side of the pressure fan 11 from air dewetting passage 1 is discharged.
Between the first finned evaporator 28 and the second finned evaporator 38, be provided with the first temperature-sensing probe 29, whether temperature control the second refrigeration system 3 detecting according to the first temperature-sensing probe 29 opens.In addition, on the first evaporator fin 28 in the first refrigeration system 2, be connected with one first hot gas bypass valve 22, whether the temperature that can detect according to the first temperature-sensing probe 29 is controlled the first hot gas bypass valve 22 and is opened.
Between the second finned evaporator 38 and finned cooler 24, be provided with one second temperature-sensing probe 37, on the second finned evaporator 38 of the second refrigeration system 3, be connected with one second hot gas bypass valve 32, the opening and close the control that is subject to the second temperature-sensing probe 37 of described the second hot gas bypass valve 32.
Operation principle of the present utility model and process are:
During start, the first refrigeration system 2 work: become high temperature and high pressure gas through the first gas-liquid separator 27 refrigerant gas out after the first compressor 21 compressions, then this high temperature and high pressure gas enters the first shell and tube condenser 23 and is cooled with cooling water generation heat exchange, then enter again finned cooler 24 and carry out again the cooling sub-cooled liquid refrigerant that becomes, through the first device for drying and filtering 25, be dried and impurity screening more afterwards, after the first expansion valve 26 reducing pressure by regulating flows, become again the gas-liquid two-phase mix refrigerant of low-temp low-pressure, this gas-liquid two-phase mix refrigerant becomes low-temp low-pressure gas from the first finned evaporator 28 out after entering the first finned evaporator 28 and air generation heat exchange cooling-air again, finally by entering the first compressor 21 after mistake the first gas-liquid separator 27, again compress, complete a circulation.In first refrigeration system 2 courses of work, the air detecting after the first finned evaporator 28 when the first temperature-sensing probe 29 reaches frosting temperature, hot gas bypass valve 22 is opened, carry out defrosting, prevent the surperficial frosting of the first finned evaporator 28, and control the second refrigeration system 3 when the first temperature-sensing probe 29 detects 8 ℃ of air themperature > after the first finned evaporator 28, open, the second compressor 31 is compressed into high-temperature high-pressure gas refrigerant by the low-temp low-pressure gas refrigerant from the second gas-liquid separator 36, then this high-temperature high-pressure gas refrigerant enters the second shell and tube condenser 33 water cooling that is cooled and becomes liquid normal temperature cold-producing medium, this liquid state normal temperature cold-producing medium is and impurity screening dry through the second device for drying and filtering 34 again, after the second expansion valve 35 reducing pressure by regulating flows, become afterwards the gas-liquid two-phase mix refrigerant of low-temp low-pressure, this gas-liquid two-phase mix refrigerant enters the second finned evaporator 38 and after air themperature is reduced again, becomes low-temp low-pressure gas from the second finned evaporator 38 out with air generation heat exchange after the first finned evaporator 28, finally by mistake the second gas-liquid separator 36, entering the second compressor 31 compresses again, complete a kind of refrigeration cycle.The air themperature that in second refrigeration system 3 courses of work, the second temperature-sensing probe 37 detects through the second finned evaporator 38, when this temperature reaches the frosting temperature of the second finned evaporator 38, the second hot gas bypass valve 32 is opened and is carried out hot gas defrosting, to guarantee the surperficial frost-free of the second finned evaporator 38.Air dewetting degree processing procedure is that fresh air is after the first finned evaporator 28 cool-down dehumidifications, if the second refrigeration system 3 is opened, air cool-down dehumidification again when through the second finned evaporator 38, to guarantee that the aridity of air reaches requirement, and then by pressure fan 11, delivered to the place that needs dry air after finned cooler 24 heating.
The utility model adopts two refrigeration systems, and dispose the first temperature-sensing probe 29 and the second temperature-sensing probe 37, the state of temperature of each point in the time of operation being detected, can automatically select according to the variation of environment temperature the unlatching quantity of refrigeration system, in the situation that ambient humidity, variations in temperature are larger, effect on moisture extraction is obvious, without heater is provided, the dry air providing meets mould except the requirement of revealing, and reduces energy consumption; In addition, in the first refrigeration system 2 and the second refrigeration system 3, be equipped with respectively the first hot gas bypass valve 22 and the second hot gas bypass valve 32, can play defrosting effect, thereby can guarantee finned evaporator surface frost-free.Moreover, after the first finned evaporator 28 and the second finned evaporator 38, finned cooler 24 is installed, this finned cooler 24 is the structure of refrigeration system itself, thereby can utilize the condenser heat of refrigeration system itself that the first finned evaporator 28, the second finned evaporator 38 low temperature drying air heat are out delivered in mold cavity after becoming air drying air again, can prevent from mould outdoor face, forming dewfall phenomenon because mould cavity temperature is too low.
