Abstract
A method for energy-saving air exchanging of a small room belongs to the field of air conditioning energy saving. An air exchanging device comprises a wall lining, a heat recovery core, fans, a CO2 sensor, a circuit control panel, a filter cover and a shutter air port. The heat recovery core is fixed in the wall lining, the two-way fan is mounted at the end of the wall lining, or one-way fans are mounted at the two ends of the wall lining respectively, and the fans and the CO2 sensor are both connected with the circuit control panel. When indoor pollutant concentration is detected by the CO2 sensor to be higher than 1000 ppm, the fans are turned on to transmit outdoor fresh air to indoor, the fans are turned on again after the turnoff of the fans are delayed so as to allow for air contraflow, turnoff of the fans are delayed again after outdoor air exhausting, cold fluid and hot fluid pass through the heat recovery core alternately, and the fans are turned off after the indoor pollutant concentration is lower than 1000 ppm. By the aid of the method, indoor air is fresh, temperature of air entering indoors in summer is not too high, and temperature of air entering indoors is not too low, so that indoor cooling and heating load is reduced, and the method is energy-saving, highly intelligent, economical and practical.
Description
Technical field:
The present invention relates to a kind of small room energy-saving scavenging method, belong to air conditioner energy saving technical field.
Background technology
Along with the raising of people's living standard, the requirement of people to indoor air environment is more and more higher, when summer air-conditioning opening and warming, people usually get used to fastening house door and window, for some occasions without VMC, as student dormitory, household bedroom, office etc., indoor CO
2constantly rise with pollutant levels such as VOC, the symptom such as cause people dizzy, drowsiness, nauseating, has a strong impact on health of people and work and study.
Window gravity-flow ventilation, affect very large by outside climatic, can cause room temperature larger fluctuation, increase building energy consumption, also can cause house dust and noise pollution, especially indoor near window personnel are difficult to stand really.Novel energy-conserving Window for ventilation, can solve the problem to a certain extent, but cost is higher, common building seldom adopts by indoor apparatus of air conditioner front end high gas is drawn outdoor, rely on indoor and outdoor pressure reduction to infiltrate indoor mode air make-up from room door and window, do not possess the function of recuperation of heat.Add gas-gas heat-exchanger rig at the indoor set of air-conditioner, the new wind of indoor exhaust wind and outdoor, by gas-gas heat-exchanger rig, can reach the object of heat recovery and air make-up, but can strengthen indoor apparatus of air conditioner size, reduces room usage space.Independently room binary channels total heat recovery air interchanger, embeds and occupy little space within the walls, but the general cost of this kind of device is higher, sometimes even can exceed the price of split air conditioner air-conditioning.Above-mentioned scavenging way, usually according to the standard design as far as possible reducing indoor fresh air load, in particular cases, as when personnel increase etc., does not reach the object of supplying new wind as required.
Therefore, in the urgent need to a kind of energy-conserving and environment-protective, economical and practical, the little intelligent room air interchanger supplying new wind as required that can meet the 20 following rooms of square meter, solve the problem.
Summary of the invention
The technical problem that the present invention solves is can for providing a kind of energy-conserving and environment-protective, economical and practical, intelligent room air exchanging method without the air-conditioned room of VMC.
The present invention is solved the problems of the technologies described above by following technical proposals: air interchanger comprises body of wall lining, heat recovery core, blower fan, CO

2sensor is all connected with circuit control panel.
In aforementioned schemes, work as CO
2sensor sensing chamber internal contamination substrate concentration; during higher than 1000ppm; after startup blower fan send outdoor new wind (50 ~ 70) s to indoor; fan parking postpones (10 ~ 20) s time; and then starting fan makes reverse air flow, to outdoor air draft (50 ~ 70) the s time, blower fan is stop delay (10 ~ 20) the s time again; cold fluid and hot fluid, alternately across heat recovery core, is now a benefit air draft cycle.Carry out several and mend air draft week after date, indoor pollution substrate concentration, lower than after 1000ppm, stops blower fan.Reach the object of air make-up and recovery ventilation heat simultaneously.
Described heat recovery core is the loose structure that highly heat-conductive material that specific heat capacity is larger is made, as foam copper, foamed aluminium, beryllium oxide ceramics, acrylic resin, the loose structure that the waste products such as discarded aluminum beverage cans are made, the vesicular texture etc. that the leftover bits and pieces of the loose structure of waste metal block erosion and steel scrap pearl, Cu-AL pipe material is piled up.
Described blower fan is a Bidirectional axial flow fan, rotating performance indifference.
Described CO
2sensor, its measurement category is 0 ~ 2000ppm.
Described circuit control panel there is CO in display room
2concentration display, and can to indoor CO
2concentration controls.
Described body of wall lining is the insulating tube that different materials is made, its shape according to installing the difference of occasion and different, as U-shaped, L-type, S type, Y type, T-shaped etc.
Described air grille both can do air outlet, can do return air inlet again, and energy regulating tuyere wind direction and flow, as being with the H type, V-type list leaf air grille etc. of filter.
As a further improvement on the present invention, described heat recovery core can radially arrange the copper pipe being filled with low boiling working fluid, strengthens recovery waste heat ability further.
As a further improvement on the present invention, described heat recovery core inner spray nozzle, utilizes a small-sized circulating water pump and tank to couple together, for room humidification, and can strengthen heat absorption capacity.
As a further improvement on the present invention, described heat recovery core can scribble hygroscopic material, dehumidifies to outdoor air.
Usefulness of the present invention, makes to enter indoor new air temperature summer and is unlikely to too high, enter indoor new air temperature winter and be unlikely to too low, reduce indoor cooling and heating load, reach energy-conservation object.In addition, outdoor dust and noise pollution can be avoided, simple, practical, economic advantage.For different human body requirements, by control circuit board, CO in control room
2concentration, the air quantity in adjusting louver air port and wind direction, thus ensure that the comfortableness of different user and the requirement of health, reach the requirement of intellectuality, hommization.About device of the present invention only needs often to overlap and spends in 200-300 unit.
Below in conjunction with drawings and Examples, the present invention will be further described.
