Abstract
The invention designs a drying refrigeration system for an air-source heat pump. The drying refrigeration system comprises a drying room, a refrigerating chamber, a sealed chamber and the air-source heat pump. A moisture exhaust pipeline is arranged in the drying room. An outlet of the moisture exhaust pipeline is communicated with the closed chamber by means of a connecting pipe. An evaporator of the air-source heat pump is arranged in the sealed chamber. A cold air outlet of the sealed chamber is communicated with the refrigerating chamber by means of a pipeline. The drying refrigeration system for the air-source heat pump has following beneficial effects: the long-term problem in a drying field that moisture exhaust gas is discharged to the atmosphere is solved such that residual cool of a dyer after heating operation is recycled for utilization; refrigeration cost is saved; and the drying refrigeration system is applicable to storage of agricultural seeds and refreshment and refrigeration of agricultural and sideline products and can be used for the field of industry and other mechanical manufacture fields and is in accord with the national policy of energy conservation and emission reduction and has obvious advantage.
Description
Art
The present invention relates to a kind of air energy heat pump and dry refrigerating system.
Background technology
In agricultural production, as Chinese medicine, vegetables, meat, melon and fruit, etc. many agricultural product all need through airing and oven dry, and common airing time long, ted often, cause the production cycle long, the unfavorable factors such as human cost is high, become the stumbling-block of restriction Agricultural Industrialization Development.Under this background elementary, dryer technology is dried drying to solution and is served vital effect; Similarly, dryer also can be used for the fields such as building materials, textile, leather, pottery, electroplating industry.Therefore, dryer is widely used in production, but existing dryer is while heating, and a large amount of cold air of generation are not recycled utilization, is but directly entered in air, causes the waste of resource and the impact of environment.
Summary of the invention
For above-mentioned Problems existing, the present invention devises a kind of air energy heat pump and dries refrigerating system, dryer can be heated cold more than rear generation recycling, for refrigeration, while economize energy, improve economic benefit.
The technical solution adopted for the present invention to solve the technical problems is: a kind of air energy heat pump dries refrigerating system, comprises baking room, refrigerating chamber, confined chamber and air energy heat pump; Described baking room is provided with dehumidifying pipelines, and be communicated with a confined chamber by tube connector in the outlet of dehumidifying pipelines, arrange the evaporimeter of air energy heat pump in confined chamber, the cold air outlet of confined chamber is communicated with refrigerating chamber by pipeline.
Described air energy heat pump comprises evaporimeter, condenser, compressor and expansion valve, by the thermodynamic cycle process allowing working medium constantly complete evaporation (heat in suction chamber external environment) → compression → condensation (releasing heat in indoor baking room) → throttling → evaporate again, thus by the transfer of heat in outer low temperature environment in baking room, refrigerant under the effect of compressor at system internal circulation flow.It completes the boosting temperature-rise period (temperatures as high 100 DEG C) of gaseous state in compressor, it enters interior machine and discharges air in heat of high temperature heating, drying room, oneself be cooled and be converted into flow liquid state simultaneously, after it runs to outer machine, the liquid evaporation of heat absorption is rapidly converted into gaseous state again, and simultaneous temperature can drop to-20 DEG C ~-30 DEG C, can be used as refrigerating chamber, at this moment the air of heat dump periphery will transfer heat to compressor continuously, is discharged by thermal energy through overcompression.
The present invention adopts a kind of air energy heat pump designed by such scheme to dry refrigerating system, solve the problem of drying field row moisture exhausting air for a long time, make dryer heat the remaining cold of rear generation and be recycled utilization, save refrigeration cost, can be used for agricultural seed deposit, agricultural byproducts be fresh-keeping, refrigeration, also can introduce the mechanical manufacturing field such as industry, meet the policy that national energy-saving reduces discharging, there is remarkable advantage.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is principle of the invention schematic diagram.
Fig. 2 is structural representation of the present invention.
In figure: 11, evaporimeter, 12, condenser, 13, compressor, 14, expansion valve, 21, baking room, 22, dehumidifying pipelines, 23, confined chamber, 24, cold air outlet, 25, pipeline, 26, refrigerating chamber, 27, air energy heat pump.
Detailed description of the invention
As shown in Figure 2, a kind of air energy heat pump dries refrigerating system, comprise baking room 21, refrigerating chamber 26, confined chamber 23 and air energy heat pump 27, described baking room is provided with dehumidifying pipelines 22, be communicated with a confined chamber 23 by tube connector in the outlet of dehumidifying pipelines 22, in confined chamber 23, arrange the evaporimeter 11 of air energy heat pump 27, the cold air outlet 24 of confined chamber is communicated with refrigerating chamber 26 by pipeline 25.
According to Fig. 1, described air energy heat pump 27 comprises evaporimeter 11, condenser 12, compressor 13 and expansion valve 14, by the thermodynamic cycle process allowing working medium constantly complete evaporation (heat in suction chamber external environment) → compression → condensation (releasing heat in indoor baking room) → throttling → evaporate again, thus by the transfer of heat in outer low temperature environment in baking room 21, refrigerant under the effect of compressor 13 at system internal circulation flow.It completes the boosting temperature-rise period (temperatures as high 100 DEG C) of gaseous state in compressor 13, it enters interior machine and discharges air in heat of high temperature heating, drying room 21, oneself be cooled and be converted into flow liquid state simultaneously, after it runs to outer machine, the liquid evaporation of heat absorption is rapidly converted into gaseous state again, simultaneous temperature can drop to-20 DEG C ~-30 DEG C, can be used as refrigerating chamber 26, at this moment the air of heat dump periphery will transfer heat to compressor 13 continuously, is discharged by thermal energy through overcompression.
The above is only the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
