The outlet of the compressor is connected with a hot air bypass valve I and a hot air bypass valve II, the outlet of the condenser is connected with an expansion valve I and an expansion valve II, both the hot air bypass valve I and the expansion valve I are communicated with one end of the evaporating tube I, both the hot air bypass valve II and the expansion valve II are communicated with one end of the evaporating tube II, both the other end of the evaporating tube I and the other end of the evaporating tube are connected with the compressor. The low temperature type constant-temperature and humidity air conditioning unit can perform defrosting and refrigeration at the same time, and reduce temperature fluctuation so as to enhance the temperature control precision, moreover the utility model can balance the supply air temperature so as to make the supply air temperature more uniform.
Description
Technical field
The utility model relates to a kind of low form thermostatic and humidistatic air conditioning unit group, relates in particular to the defroster of the evaporimeter of low form thermostatic and humidistatic air conditioning unit group.
Background technology
Because the temperature of low form thermostatic and humidistatic air conditioning unit group working environment is very low, evaporator surface can frosting.Opening electric heater heated defrosting to evaporator surface when the method that solves generally was defrosting.Because defrost process need heat evaporator surface, so energy consumption is very big.A kind of refrigerator that provides in the Chinese utility model patent of publication number for CN2624135 of announcing on July 7th, 2004 stores up defroster automatically, condenser, the device for drying and filtering that is connected with condenser and capillary that its refrigerant cycle apparatus comprises compressor, is connected with compressor by high-voltage tube, capillary is connected with evaporimeter, evaporimeter is connected with compressor by low-voltage tube, refrigerant cycle apparatus also includes the liquid storage pipe that is connected with condenser, liquid storage pipe is connected with cross valve, and cross valve also is connected with evaporimeter with compressor.This technology is compared with adopting electric-heating technology, adopting refrigeration compressor to be discharged into useless heat that outdoor condenser distributes is reclaimed and replaces the electric heater energy to defrost, a large amount of energy consumptions have been saved, but its defrost process can not be freezed, cause temperature recovery and make temperature fluctuation very big, control accuracy of temperature is low.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of low form thermostatic and humidistatic air conditioning unit group, and the simultaneous temperature that effectively defrosts fluctuation is very little, and wind pushing temperature is even.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: low form thermostatic and humidistatic air conditioning unit group of the present utility model, comprise compressor, condenser, evaporimeter, the defrosting temperature sensor, controller, described evaporimeter comprises evaporation tube I and evaporation tube II, described evaporation tube I and described evaporation tube II each other arranged crosswise on evaporimeter, the outlet of described compressor is connected with hot gas bypass valve I and hot gas bypass valve II, the outlet of described condenser is connected with expansion valve I and expansion valve II, described hot gas bypass valve I and described expansion valve I are communicated with the end of evaporation tube I, described hot gas bypass valve II and described expansion valve II are communicated with the end of evaporation tube II, and the other end of the other end of described evaporation tube I and evaporation tube II all is connected with compressor.
Further, the fin of described evaporimeter is provided with the defrosting temperature sensor, and described defrosting temperature sensor is connected with controller.
The utility model is owing to adopt technique scheme, and this low form thermostatic and humidistatic air conditioning unit group can be moved defrosting and refrigeration simultaneously, has improved temperature control precision thereby reduce temperature fluctuation, and the balanced draft temperature, makes the wind-warm syndrome degree of sending even.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the system works schematic diagram of the utility model low form thermostatic and humidistatic air conditioning unit group.
The specific embodiment
As shown in Figure 1, the utility model comprises compressor 1, condenser 2, evaporimeter 3, defrosting temperature sensor 4, controller 5.Evaporimeter 3 comprises evaporation tube I6 and evaporation tube II7, evaporation tube I6 and evaporation tube II7 are set to two autonomous systems of arranged crosswise, on the fin of evaporimeter 3, be provided with defrosting temperature sensor 4, defrosting temperature sensor 4 is connected with controller 5, so controller 5 can be according to the signal controlling defrost process of defrosting temperature sensor 4 feedbacks; Be connected with hot gas bypass valve I8 and hot gas bypass valve II9 in compressor 1 exit, the outlet of condenser 2 is connected with expansion valve I10 and expansion valve II11, hot gas bypass valve I and described expansion valve I10 are communicated with the end of evaporation tube I6, hot gas bypass valve II9 and described expansion valve II11 are communicated with the end of evaporation tube II7, and the other end of the other end of evaporation tube I6 and evaporation tube II7 all is connected with compressor 1; Hot gas bypass valve I8 and hot gas bypass valve II9 are common magnetic valves, and they can both realize conducting or shutoff under the control of controller 5 as the bypass line of condenser 2.
Use this defroster, controller 5 judges according to defrosting temperature sensor 4 feedacks whether needs start defrosting to unit, open hot gas bypass valve I8 in the time of need beginning to defrost, the part superheated steam that refrigeration compressor 1 is discharged into condenser 2 passes through the evaporation tube I6 that hot gas bypass valve I8 enters evaporimeter 3, pressure reduction diminishes and closes automatically before and after this moment expansion valve I10, evaporation tube I 6 defrosts, and evaporation tube II7 still freezes.Controller 5 judges according to defrosting temperature sensor 4 feedacks whether evaporation tube I6 defrosting finishes, close hot gas bypass valve I8 when needing to finish evaporation tube I6 defrosting, pressure reduction becomes big unlatching automatically before and after the expansion valve I10, evaporation tube I6 recovers refrigeration, open hot gas bypass valve II9 simultaneously, the part superheated steam that refrigeration compressor 1 is discharged into condenser 2 enters the evaporation tube II7 of evaporimeter 3 through hot gas bypass valve II9, and pressure reduction diminishes and closes automatically before and after this moment expansion valve II11, and evaporation tube II7 defrosts.Controller 5 judges according to defrosting temperature sensor 4 feedacks whether evaporation tube II7 defrosting finishes, and needs to finish to close hot gas bypass valve II9 when evaporation tube II7 defrosts, and pressure reduction becomes big unlatching automatically before and after the expansion valve II11, and evaporation tube II7 recovers refrigeration.Refrigerating operaton all recovers in back two systems of circulation that 3 two systems of end evaporimeter replace defrosting, and whether the 4 automatic judgement defrostings of defrosting temperature sensor enter next circulation.Evaporimeter 3 is designed to evaporation tube two systems of arranged crosswise each other, and hot gas only enters evaporimeter 3 one of them system during defrosting, and simultaneously another system freezes, and can not make temperature fluctuation big because of defrosting like this, arranged crosswise also balance wind pushing temperature.
