Description

The full heat recovery type fresh air air conditioner of a kind of solution

Technical field

The utility model relates to air-conditioning technical field, relates in particular to the air conditioner that has the solution heat regenerator.

Background technology

Existing air-conditioning system mostly adopts return air to add the pattern of new wind, but because most of air being discharged to of, making that pollutant can not be very fast in indoor circulation is outdoor, harm humans health.Strengthen the resh air requirement method of operation of brand-new wind (or adopt), can indoor harmful substance dilute and discharge outdoorly, obviously improve indoor air quality.But then, the increase of resh air requirement makes new wind handle energy consumption increases greatly.

Adopting heat reclamation device, reclaim the energy of indoor exhaust wind, is to reduce the effective measures that new wind is handled energy consumption.Can reclaim sensible heat, the efficient that can reclaim the full heat recovery device of latent heat again will be higher than heat recovering device.The full heat recovery device that adopts mainly contains at present: rotary-type full heat regenerator, the full heat regenerator of fin plate type and the full heat regenerator of heat-pump-type.Preceding two kinds of full heat regenerators can not be avoided the cross pollution of new wind and air draft, so the gas that flows through must be innocuous substance, otherwise can cause cross-infection.Though the full heat regenerator of heat-pump-type can be avoided the contacting of new wind and air draft, pollution, heat recovery efficiency own is not high, and investment, self energy consumption be all than higher, thereby has limited its application to a certain extent.

The utility model content

The purpose of this utility model provides a kind of fresh air conditioner machine that has the full heat regenerator of solution.

The utility model solution heat recovery type fresh air air conditioner is made up of refrigeration system and full heat recovery system two parts.Refrigeration system is by the compressor 2 of freon refrigeration device, evaporimeter 1, and condenser 4, expansion valve 3, auxiliary condenser 5 and two solution air-to-air total heat exchanger E, F, solution pool 7,9, and plate type heat exchanger 11 is formed (see figure 1)s.Solution total-heat exchanger E is linked to each other by solution pump 10 by pipeline with solution pool 9, evaporimeter 1.Solution total-heat exchanger F has pipeline to pass through solution pump 10 with solution pool 7, condenser 4 to link to each other.Having pipeline to pass through plate type heat exchanger 11 between the solution pool 7 and 9 links to each other.Full heat recovery system is made up of four solution total-heat exchanger A, B, C, D.A, B are connected into one group in four solution air-to-air total heat exchanger A, B, C, the D (see figure 1), and C, D are connected into one group, and two groups are arranged in juxtaposition into a full heat recovery system.A, B series connection group, C, D series connection group have pipeline to pass through solution pump 10 respectively to link to each other with solution pool 8.

This new wind place air conditioner course of work is as follows:

In full heat recovery system, there are two solution pumps 10 to control the flow of two-stage spray solution respectively.In each level, solution flow to solution total-heat exchanger A from solution tank 8 under the driving of solution pump 10, flow down from liquid distributor then and soak filler.Solution contacts with return air in filler, and the exchange process of heat and quality takes place.Afterwards, solution flows under the influence of gravity into solution total-heat exchanger B, same and new wind generation caloic exchange process.At last, solution is got back in the solution tank 8, finishes whole circulation.In summer, the water capacity of outdoor new wind and temperature all are higher than the state of indoor return air.Solution contacts with return air in solution total-heat exchanger A, C, and solution is lowered the temperature concentrated, and return air is heated humidification; Solution contacts with new wind in solution total-heat exchanger B, D, and solution is heated dilution, and new wind is by cool-down dehumidification.Like this, be media with solution, can realize the full heat exchange of new wind and return air.The temperature and the water capacity of new wind all reduce, and damp and hot air draft is discharged from full heat regenerator.

Through the new wind of the full heat regenerator D of solution, B,, sent into indoor after the solution spraying cooling by evaporimeter 1 cooling through solution total-heat exchanger E.Indoor return air also is at first to pass through solution total-heat exchanger A, C, then through the be condensed solution spraying of device 4 heating of solution total-heat exchanger F, directly arranges to outdoor through auxiliary condenser 5 backs again.Auxiliary condenser 5 is used to discharge the condensation heat of refrigeration system.When the solution concentration in the solution tank 7 is higher, show that solution reactivation heat demand is few, promptly the heat exhaust in the condenser 4 needs to reduce, and at this moment opens auxiliary condenser 5, discharges unnecessary condensation heat.When the solution concentration in the solution tank 7 is low, show that the heat of solution regeneration needs increases, promptly need many heat extractions from condenser 4, at this moment close auxiliary condenser 5.The opening and closing of auxiliary condenser are by magnetic valve 6 controls.

Solution system is divided into two parts in the fresh air conditioner machine: a part is the working media as full heat recovery system, this part solution accumulates in the intermediate solution groove 8, another part be respectively with the solution of condenser and evaporimeter heat exchange, accumulate in respectively in left solution tank 7 and the right solution tank 9.There is the exchange of quality in solution in left side solution tank 7 and the right solution tank 9 by plate type heat exchanger 11.

This fresh air conditioner machine is owing to having adopted the full heat regenerator recovery waste heat of solution, freon refrigeration device refrigeration and the heat exchange of solution air-to-air total heat exchanger, so new wind processing energy consumption is low.Can avoid the cross infection of air-flow, can remove the dust and the bacterium of carrying secretly in the air, play the effect that purifies air by the spray of solution.
