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 the energy-conservation air exchanging method in a kind of small-sized room, belong to the air conditioner energy saving technical field.
Background technology
The Along with people's growth in the living standard, people to indoor air environment require increasingly high, at summer air-conditioning during open and warming; People usually get used to fastening the house door and window, for the occasion of some no VMCs, like student dormitory; Household bedroom, office etc., indoor CO
2Constantly rise with pollutant levels such as VOC, cause symptoms such as people are dizzy, drowsiness, nauseating to have a strong impact on health of people and work and study.
The gravity-flow ventilation of windowing receives extraneous climatic effect very big, can cause room temperature than great fluctuation process, increases building energy consumption, also can cause house dust and noise pollution, and especially indoor personnel near the window are difficult to stand really.The novel energy-conserving Window for ventilation; Can address the above problem to a certain extent, but cost is higher, common building seldom adopts through drawing indoor apparatus of air conditioner front end high gas outdoor; Door and window infiltrates indoor mode air make-up from the room to rely on indoor and outdoor pressure reduction, does not possess the function of recuperation of heat.Add gas-gas heat-exchanger rig in indoor machine of air-conditioner, indoor exhaust wind and outdoor new wind can reach the purpose of heat recovery and air make-up, but can strengthen the indoor apparatus of air conditioner size through gas-gas heat-exchanger rig, reduce the room usage space.The full heat recovery air interchanger of independent room binary channels embeds and to occupy little space within the walls, but the general cost of this type 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 that reduces indoor new wind load as far as possible, in particular cases, when increasing like personnel etc., does not reach the purpose of supplying new wind as required.
Therefore, press for a kind of energy-conserving and environment-protective, economical and practical, the little intelligent room air interchanger of supplying new wind as required that can satisfy the following room of 20 square meters, address the above problem.
Summary of the invention
The technical problem that the present invention solves is that a kind of energy-conserving and environment-protective, economical and practical, intelligent room air exchanging method can be provided for the air-conditioned room of no VMC.
The present invention solves the problems of the technologies described above through following technical proposals: air interchanger comprises body of wall lining, recuperation of heat core body, blower fan, CO
2Sensor, circuit control panel, filter mantle, air grille; Its annexation is to be fixed with the recuperation of heat core body in the body of wall lining, two-way blower fan or two unidirectional blower fans is housed, blower fan and CO in the end of body of wall lining
2Sensor all links to each other with circuit control panel.
In the aforementioned schemes, work as CO
2Sensor sensing chamber internal contamination substrate concentration, when being higher than 1000ppm, start blower fan to indoor send outdoor new wind (50 ~ 70) s after; Blower fan is shut down and is postponed (10 ~ 20) s time; And then starting fan makes reverse air flow, and to outdoor air draft (50 ~ 70) the s time, blower fan is shut down delay (10 ~ 20) the s time again; Cold fluid and hot fluid is alternately through the recuperation of heat core body, and be a benefit air draft cycle this moment.Carry out several and mend air draft week after date, after the indoor pollution substrate concentration is lower than 1000ppm, stop blower fan.Air make-up and the purpose that reclaims the ventilation heat have been reached simultaneously.
Described recuperation of heat core body is the loose structure that the bigger highly heat-conductive material of specific heat capacity is processed; Like foam copper; Foamed aluminium, beryllium oxide ceramics, acrylic resin; The loose structure that discarded waste products such as aluminum beverage can are processed, the vesicular texture that the leftover bits and pieces accumulation of loose structure that the erosion of waste metal piece forms and steel scrap pearl, copper aluminium tube forms etc.
Described blower fan is a two-way axial flow blower, rotating performance indifference.
Described CO
2Sensor, its measurement category are 0 ~ 2000ppm.
CO in the display room is arranged on the described circuit control panel
2The concentration display, and can be to indoor CO
2Concentration is controlled.
Described body of wall lining is the insulating tube that different materials is processed, and its shape is according to the difference that occasion is installed and difference, like U type, L type, S type, Y type, T type etc.
Described air grille both can be done air outlet, can do return air inlet again, and can regulate air port wind direction and flow, like the single leaf air grille of H type, V-type of band filter etc.
As further improvement of the present invention, described recuperation of heat core body can radially be arranged the copper pipe that is filled with low boiling working fluid, further strengthens the recovery waste heat ability.
As further improvement of the present invention, the built-in nozzle of described recuperation of heat core body utilizes a small-sized water circulating pump and tank to couple together, and is used for the room humidification, and can strengthens heat absorption capacity.
As further improvement of the present invention, described recuperation of heat core body can scribble hygroscopic material, and outdoor air is dehumidified.
Usefulness of the present invention makes the new wind-warm syndrome degree in the inlet chamber in summer be unlikely to too high, and the interior new wind-warm syndrome degree of inlet chamber in winter was unlikely to low, had reduced indoor cooling and heating load, reached energy-conservation purpose.In addition, can avoid outdoor dust and noise pollution, simple, practical, economic advantage.To different human body requirements, through control circuit board, CO in the control room
2Concentration is regulated the air quantity and the wind direction of air grille, thereby has been guaranteed the comfortableness of different user and the requirement of health, has reached requirement intelligent, hommization.Device of the present invention only needs every cover to spend in about 200-300 unit.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
