Description
Technical field
The utility model relates to a kind of energy recovery equipment, is specifically related to a kind of full recuperation of heat unit with bypass pipe, is used for reclaiming air-conditioning air draft waste heat.
Background technology
Chinese annual completion construction area is about 2,000,000,000 m at present
2, wherein public building has 400,000,000 m approximately
2In the annual energy consumption of public building (particularly megastore, hotel, high-grade hotel, high-grade office building etc.), about 50%～60% is consumed in air conditioner refrigerating and heating system, and 20%～30% is used for illumination.And in this part energy consumption of air-conditioning heating, about 20%～50% by peripheral structure conduct heat consume (hot summer and warm winter region is about 20%, and the Xia Redong cryogenic region is about 35%, and cold district is about 40%, severe cold area about 50%).From the present circumstances analysis, these are built at building enclosure, heating and air-conditioning system, and the illumination aspect, the potentiality of total energy savings 50%.The heating air conditioning energy-saving potential is maximum, and aspect design of HVAC, controlling just can the effective energy-saving energy.And the latent heat load that new wind brings can account for 20%～40% of air-conditioning total load, therefore develops the key subjects that energy-conservation VMC is a building energy saving field.
Full recuperation of heat unit is a kind of air energy reclaimer, and by blower fan, full recuperation of heat runner, filter etc., common mounting means is divided into two kinds: the heat recovery system (Fig. 1) of not establishing bypass usually; Be characterized in small investment; Simple installation, take up an area of to economize, but the transition season that need not reclaim heat (spring, Qiu Liangji) increased fan energy consumption (transition season the inner air and outer air temperature be more or less the same, if heat recovery equipment still turns round; Do not have temperature difference exchange, but blower fan requires the expenditure of energy still.); The heat recovery system (Fig. 2) of bypass is set, is characterized in that transition season is new, air draft is walked around heat reclamation device through bypass pipe, do not increase fan energy consumption; Use this mounting structure; Need manual work to open or close bypath valve, the one side system complex, machine room area increases; The manual control real-time is poor on the other hand, and is also more loaded down with trivial details.
Summary of the invention
The utility model purpose provides a kind of full recuperation of heat unit with bypass pipe, through the improvement of structure, makes system realize automation, and is in real time controlled strong, need not manual intervention.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of full recuperation of heat unit with bypass pipe comprises blower fan, heat exchange runner, filter and connects the ventilating duct of each equipment that said ventilating duct is positioned at outdoor new wind inlet and the exhaust outlet of being provided with; Ventilating duct is positioned at indoor air outlet and the return air inlet of being provided with; Said heat exchange runner two ends also are connected to the bypass air channel, and said new wind porch is provided with enthalpy probe, the signal output part of this enthalpy probe with have the control of software device and be connected; Said bypass air channel is provided with magnetic valve, and the control end of this magnetic valve is connected with the said control of software device that has.
In the technique scheme, said enthalpy probe is for detecting the sensor of enthalpy in the air, and airborne enthalpy is meant the total amount of heat that contains in the air, and the unit mass with dry air is a benchmark usually, is called specific enthalpy.Abbreviate enthalpy in the engineering as, be meant one kilogram of dry air enthalpy and with the summation of the enthalpy of its corresponding steam.On engineering, we can judge that air obtains heat or lost heat according to the variation of air specific enthalpy in processing procedure of certain mass.The specific enthalpy of air increases to be represented to obtain heat in the air; The specific enthalpy of air reduces to represent to have lost in the air heat.The utility model is provided with the enthalpy probe in new wind porch; The outdoor new wind enthalpy that detects is transferred to has in the control of software device; By the enthusiasm of predefined algorithm judgement air draft recuperation of heat this moment, be lower than the whole Energy Efficiency Ratio (air conditioner refrigerating amount/power consumption) of air-conditioning system like heat recovery system Energy Efficiency Ratio (reclaiming heat/blower fan power consumption), then drive the magnetic valve on the bypass air channel; Open bypass, close the heat exchange runner; Otherwise, then open the heat exchange runner, close the magnetic valve on the bypass air channel.Through measuring the variation of enthalpy, the outer indoor air enthalpy of Control Room changes in real time, opens bypass by controller in good time, and cost greatly cuts down the consumption of energy.Saidly have a robot control system(RCS) that the control of software device can use air-conditioning system self, need not to increase the control appliance cost.
In the technique scheme, said new wind porch is provided with moisture probe, and the signal output part of this moisture probe is connected with the said control of software device that has.Through adding the detected value of humidity, controller can accurately be judged the period in transition season.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because the utility model is provided with the enthalpy probe in new wind porch, on the bypass air channel, is provided with magnetic valve, detects the enthalpy of fresh wind port by the enthalpy probe in real time; Have the control of software device according to recording data; Compare with the data that default in the controller, judge whether to open or close the bypass air channel, when opening the bypass air channel; Close the heat exchange runner, otherwise then open; Automatically a whole set of air draft heat recovery system of control need not manual intervention, and administrative staff are frequently switched the workload of unit operational mode when having reduced season alternation greatly, have good energy-conservation performance and practicality;
2, the utility model is through the real-time detection data of moisture probe and enthalpy probe; Have the control of software device and whether judge transition season according to recording data, the preset value in the comparison controller is opened bypass air channel magnetic valve in good time; Reduce system energy consumption, reduce operating cost;
3, avoid the frequent transitions operating mode of unit, improve unit durability.
