Description

Energy-saving brand-new air dehumidifier

Technical field

The utility model relates to a kind of dehumidifier, relates in particular to a kind of energy-saving brand-new air dehumidifier that adopts heat reclamation device.

Background technology

Brand-new air dehumidifier is used widely in the various occasions that brand-new wind dehumidifying demand is arranged with its unique air-treatment mode and engineering adaptability, as defence engineering, deposit the warehouse of venomous injurant etc.But we know that brand-new air dehumidifier does not have return air, and the new wind of the outer high hot high humidity of whole process chambers is compared with the dehumidifier of return air type, and the energy consumption of usually brand-new air dehumidifier itself is very big, and a large amount of energy of exhaust air is just discharged outdoor also very unfortunate without utilization.Though existing brand-new air dehumidifier can satisfy the demand of brand-new wind dehumidifying, energy consumption is higher, and this energy-saving and emission-reduction policy with country deviates from, and has also proposed new problem to us.And the stand-alone device volume is bigger sometimes, can not pass through short and small door opening smoothly.

Summary of the invention

Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of brand-new air dehumidifier of high-efficiency and energy-saving type that can satisfy brand-new wind dehumidifying demand and have better engineering adaptability is provided.

Technical scheme: a kind of energy-saving brand-new air dehumidifier, it comprises prime temperature adjusting and dehumidifying system and back level cool-down dehumidification system and heat regenerator, the temperature adjusting and dehumidifying system is connected in series layout successively by preceding stage compressor, water-cooled condenser, air-cooled condenser, prime heating power expansion valve and prime evaporimeter, also is serially connected with magnetic valve and one way stop peturn valve that the control refrigerant flows in the circuit of water-cooled condenser and air-cooled condenser; The cool-down dehumidification system is connected in series layout successively by back stage compressor, water-cooled condenser, back level heating power expansion valve and a back level evaporimeter, prime evaporimeter and back level evaporimeter arranged in series before and after the air-flow direction; Heat regenerator is located between air-cooled condenser and the prime evaporimeter, outdoor new wind is entered by the admission line inlet of heat regenerator, the admission line outlet of heat regenerator is communicated with the prime evaporimeter, the outlet pipe of back level evaporimeter is communicated with the outlet pipe inlet of heat regenerator, the outlet pipe outlet of heat regenerator is communicated with air-cooled condenser, the outlet pipe of air-cooled condenser is communicated with blower fan, by blower fan processed air is sent.

Wherein, described heat regenerator is the plate-fin heat regenerator.

General structure of the present utility model is a modularized combination type, is combined by dehumidifying section, heat-recovery section and three modular units of hot again air supply section.

The dehumidifying section is carried out the cool-down dehumidification processing to air, mainly comprises evaporimeter and captation that two-stage is separate; Heat-recovery section is to new wind precooling, and is hot again to the air-out of dehumidifying section, mainly comprises plate-fin heat regenerator and captation; Hot again air supply section carries out heat treatment again to the air that goes out for the second time heat regenerator, and the air after will handling simultaneously is transported to the destination, mainly comprises air-cooled condenser, centrifugal blower and compression refrigerating apparatus.The utility model can adopt the PLC control mode to control according to temperature, humidity index easily, mainly controls the unlatching or the closed condition of compression set refrigerating capacity, magnetic valve respectively, thereby has determined the heat again that needs.

The new wind that enters from heat regenerator passes through prime and two evaporimeter cool-down dehumidifications of back level successively, and then get back to heat regenerator, carry out the wet exchange of heat with the new wind that newly enters heat regenerator, send into air-cooled condenser after being heated, heat after blower fan is discharged to the space that needs through air-cooled condenser.When the enthalpy of outdoor new wind is higher than a certain setting value, prime temperature adjusting and dehumidifying system and back level cool-down dehumidification system move simultaneously, the magnetic valve C of temperature adjusting and dehumidifying system closes, D opens, cold-producing medium is compressed to the gas of HTHP in compressor, the liquid of warm high pressure in after the water-cooled condenser condensation, becoming, after magnetic valve D passes through the heating power expansion valve throttling, become the vapour-liquid two-phase mixture of low-temp low-pressure, enter evaporimeter, evaporate and absorb the new wind-heat amount by evaporimeter within it, after become low-temp low-pressure gas and sucked by compressor, finish a kind of refrigeration cycle.The course of work of cool-down dehumidification system is identical with the temperature adjusting and dehumidifying system.When the enthalpy of outdoor new wind is lower than a certain setting value, the operation of temperature adjusting and dehumidifying system, the cool-down dehumidification system is out of service.Determine the unlatching of magnetic valve C, D or close that when if leaving air temp is lower, D opens according to leaving air temp, C closes.Cold-producing medium enters evaporimeter from compressor through water-cooled condenser and heating power expansion valve, and air enters heat regenerator and carries out discharging after the heat exchange with the air that newly advances behind the evaporimeter cool-down dehumidification.If leaving air temp is higher, D closes, and C opens, cold-producing medium enters evaporimeter from compressor through air-cooled condenser and heating power expansion valve, and air enters heat regenerator and carries out discharging after the heat exchange with the air that newly advances behind the evaporimeter cool-down dehumidification, again after air-cooled condenser heating, discharge at last through blower fan.

Beneficial effect: (1) the utility model is applied to the plate-fin heat regenerator in the brand-new air dehumidifier, and energy-saving effect is obvious, compares with common brand-new air dehumidifier, and the unit power moisture removal can improve 21%, and dependable performance is stable.(2) adopt fabricated structure, the integrated level height has better engineering adaptability.
