Fig. 1~4 are referred to, embodiment of the present utility model provides a kind of air energy drying system, including：

Hothouse 2；

Air source heat pump 1, it includes being in turn connected into the filter 11 of closed-loop path, expansion valve 12, evaporator 13, compression Machine 14 and condenser 15；The evaporator 13 includes evaporative cylinder 131, is built in the shape of a spiral and coaxially the evaporative cylinder 131 Evaporation tube 132, the radial multiple evaporation fins 133 being fastened on the evaporation tube 132 and located at the evaporation tube 132 1 The evaporation fan 134 of side, the condenser 15 includes the condensation framework for being horizontally placed on the first madial wall 21 of the hothouse 2 151st, it is embedded in the condenser pipe 152 of the condensation framework 151, is evenly arranged in institute successively along the length direction of condenser pipe 152 State multiple condensing fins 153 on condenser pipe 152；The two ends of evaporation tube 132 are connected with expansion valve 12 and compressor 14 respectively, The two ends of condenser pipe 152 are connected with the filter 11 and compressor 14 respectively；

Electric heater 6, it is horizontally placed on the second madial wall 22 of the hothouse 2；

Circulating fan 3, it includes the first blower fan 31 and the second blower fan 32, and first blower fan 31 is built in the hothouse 2 bottoms and its air intake, which are rectified, to be rectified to the condenser pipe 152, air-out to second madial wall 22, in second blower fan 32 It is placed in the top of hothouse 2 and the symmetrical electric heater 6 of its air intake, air-out is rectified to first madial wall 21；And

Temperature sensor 4, its test side is built in the hothouse 2 and for detecting the temperature in the hothouse 2；

Wherein, the madial wall 22 of the first madial wall 21 and second be arranged in parallel.

During specific effect, the refrigerant of lower temperature enters in evaporation tube 132, under fan action, and air passes through evaporation Gap between pipe 132 and the refrigerant transferred heat in evaporation tube 132, refrigerant temperature raise and move to compressor 14, in the presence of compressor 14, refrigerant temperature is raised and into condenser 15 again, and is distributed heat by condenser 15 To hothouse 2, temperature sensor 4 is then monitored in real time can pass through air-source heat under the drying temperature in hothouse 2, conventional situation Pump 1 is heated, and when being not enough to the drying temperature of offer demand by air source heat pump 1, can open self-heating device pair Hothouse 2 is heated；Wherein, the air intake of the first blower fan 31 of the present embodiment circulating fan 3 is rectified to condenser 15, can will be cold The hot-air that condenser 15 is heated is pumped into, and by just being discharged to the outlet air end of the first blower fan 31 of the second madial wall 22, its is favourable In the heat produced efficiency for promoting condenser 15, promote the drying efficiency of hothouse 2, while setting the air intake of the second blower fan 32 to rectify Electric heater 6, air-out are rectified to the first madial wall 21, its one side, which is conducive to coordinating with the first blower fan 31, promotes hothouse 2 Interior air circulation, the air flow on the other hand then advantageously ensuring that the heating of electric heater 6, promote the heating effect of electric heater 6 Rate.For the ease of the circulation of above-mentioned air to improve drying efficiency, the present embodiment condenser 15 and electric heater 6 are close to drying The middle part of room 2 is set, so as to ensure the harmony of heat transfer.

In order to improve utilization rate of the air source heat pump 1 to air energy, evaporation tube 132 is set to spiral helicine by the present embodiment Coil pipe, specifically, evaporation tube 132 is gradually spiral forms from the inside to the outside, and evaporates fin 133 and is radially arranged along evaporation tube 132, I.e. multiple evaporation radial arrangements of fin 133, on the one hand its can fix evaporation tube 132, on the other hand increase heat transference efficiency； Moreover, the present embodiment can be connected from beginning to end along the axially arranged multiple evaporation tubes 132 of evaporative cylinder 131, two neighboring evaporation tube 132, So as to increase the contact area of evaporation tube 132 and air in evaporative cylinder 131, and then improve the utilization ratio of air energy.

And distributing for the ease of the heat of condenser 15, the present embodiment condensation framework 151 embed condenser pipe 152 so that Condenser pipe 152 can directly with the air contact in hothouse 2, while being arranged condensing fin 153 on condenser pipe 152 to promote heat The transfer rate of amount, while setting the first blower fan 31 to coordinate extracts the air that condenser pipe 152 is heated, it is ensured that the heat of condenser pipe 152 Distribute.

Condenser pipe 152 described in the present embodiment include along it is described condensation the length direction of framework 151 be evenly arranged successively it is multiple 152a is in charge of in condensation, and 152a head and the tail connections are in charge of in the two neighboring condensation, and two neighboring condensation is formed between being in charge of 152a Airflow clearance, in the presence of the first blower fan 31, air-flow is constantly in charge of the gap 152a through condensation, and then ensures higher Heat produced efficiency.Wherein, the two neighboring condensing fin 153 being in charge of on 152a that condenses of the present embodiment is staggered, so that just In staggeredly radiating for condensing fin 153, it is conducive to the rate of heat dispation for improving condensing fin 153.

Under self gravitation and air-flow double action, condenser 15 is vulnerable to the effect of larger downward power, therefore this reality The support 154 that the example condenser 15 also includes being obliquely installed is applied, described one end of support 154 connects with first madial wall 21 Connect, the other end is connected with the middle part of condensation framework 151, it can play a supporting role to condenser 15, extension condenser 15 Service life.

Due to by personal monitoring's temperature sensor 4 and controlling the switch of electric heater 6 that there is hysteresis quality, therefore the present embodiment The air energy drying system also includes a radiator valve 5, and it includes being used to gather the detection temperature of temperature sensor 4 production The temperature signal collection circuit 51 of raw electric signal, for compare the electric signal whether be less than first threshold first compare it is electric Road 52, for driving the first drive circuit 53 that the electric heater 6 heats when electric signal is less than first threshold, for comparing Whether the electric signal is more than the second comparison circuit 54 of Second Threshold, for being driven when the electric signal is more than Second Threshold The electric heater 6 stops the second drive circuit 55 of heating；Wherein, the first threshold is less than Second Threshold.The present embodiment Temperature in hothouse 2 is controlled by radiator valve 5, it is to avoid too high or too low for temperature in hothouse 2, it advantageously ensures that dry Equilibrium in dry room 2 is dried.Specifically, the present embodiment by temperature sensor 4 in real time monitoring hothouse 2 in air themperature simultaneously Electric signal is produced, and above-said current signal is gathered by temperature signal collection circuit 51 in real time, when the temperature of air in hothouse 2 is low When setting value, then electric signal is less than first threshold, and it can drive electric heater 6 to be heated to supplement air source heat pump 1 Deficiency, and when the temperature of air in hothouse 2 is higher than setting value, then electric signal is more than Second Threshold, it can drive electrical heating Device 6 stops heating avoiding temperature in hothouse 2 too high.
