Description

A kind of fresh air energy-saving control method detected with CO
Technical field
The present invention relates to air conditioner fresh air field, particularly relate to a kind of fresh air energy-saving control method detected with CO.
Background technology
Air-conditioning and air conditioning (air conditioning), refer to and use artificial means, the parameter such as temperature, humidity, cleanliness factor, speed of building/structures environment air carried out to the process of regulation and control.Generally comprise low-temperature receiver/heat resource equipment, cold and hot medium distributing system, a few major part such as end equipment and other auxiliary equipment.Mainly comprise water pump, blower fan and pipe-line system.The cold and hot amount utilizing transmission & distribution then is responsible for by end equipment, specifically processes air, makes the air parameter of target environment reach requirement.
Air-conditioning is divided into single cold air-conditioning and air conditioner for both cooling and heating, and operation principle is the same, and the cold-producing medium of air-conditioning general use mostly is in the past freon.The characteristic of freon is: when becoming liquid state from gaseous state, discharges a large amount of heats.And when being gaseous state by liquid state, a large amount of heats can be absorbed.I.e. first endothermic gasification liquidation exothermic reaction again.Air-conditioning be exactly accordingly principle design.
The refrigerant compression of gaseous state is the gaseous refrigerant of HTHP by compressor, becomes the liquid refrigerant of normal temperature high voltage after then delivering to condenser (off-premises station) heat radiation, so off-premises station produces by boasting is hot blast.
Then capillary is arrived, enter evaporimeter (indoor set), suddenly increase because cold-producing medium arrives evaporimeter rear space from capillary, pressure reduces, and liquid cold-producing medium will be vaporized, and becomes the cold-producing medium of gaseous state low temperature, thus absorb a large amount of heats, evaporimeter will turn cold, and the air of indoor is blown over by the fan of indoor set from evaporimeter, so indoor set produces by boasting is exactly cold wind; Will water droplet be condensed into after water vapour in air runs into cold evaporimeter, spill out along water pipe, the reason of air-conditioning meeting water outlet that Here it is.
Have the parts being cross valve when heating, make cold-producing medium at the flow direction of condenser and evaporimeter with contrary during refrigeration, so when heating, outdoor blows is cold wind, what indoor set blew is hot blast.
The principle of heat will be absorbed when will discharge heat and vaporization (becoming gas from liquid) time liquefaction (the becoming liquid state from gas) of acquiring in the junior physics being exactly in fact.
Air-conditioning is do cold and hot exchange to indoor and outdoors in fact, generally all requires indoor airtight, long-time using air-condition, indoor air can be made very dirty.For such situation, just there is VMC.
VMC is according to sending new wind at airtight indoor side special equipment to indoor, then from opposite side by special equipment to outdoor discharge, the principle of " new wind flow field " can be formed in indoor, thus meet the needs of indoor fresh air ventilating.Embodiment is: adopt high-head, large discharge small power DC high-speed brushless driven by motor centrifugal blower, rely on machinery powerful by side to indoor air-supply, to be forced to the mode of outdoor discharge with the new blower fan of custom-designed air draft by opposite side and form new wind flow field in system.The filtration of new wind, the poison that goes out, sterilization, oxygenation, preheating (winter) is entered to entering indoor air while air-supply.Air draft carries out recuperation of heat exchange through main frame and new wind, reclaims most of energy and sends indoor back to by new wind.Use the scheme forming clean room on a large scale, ensure that it is clean for entering indoor air.The object of indoor air purification environment is reached with this.
Existing VMC is all generally Non-follow control, and existing VMC is all generally directly introduce outside air, discharges foul indoor air simultaneously, if indoor/outdoor temperature-difference is comparatively large, then indoor heat energy/cold energy loss is larger.
In addition, if CO concentration over-standard is easy to apnea time occurs in confined space, existing new wind function generally all can not be opened when indoor CO exceeds standard automatically.
Patent " fresh air ventilator " (application number: 200710178748.0 applyings date: 2007-12-05) discloses a kind of fresh air ventilator, this ventilator comprises a housing closed, this housing closed is respectively equipped with and one first opening of indoor conducting and one second opening with outdoor conducting, in the housing closed between the first opening and the second opening, swingingly be provided with a centrifugal fan, the air inlet of this centrifugal fan and the corresponding switched conductive of air outlet difference are in the first opening and the second opening.Only arrange a ventilation shaft by the second opening between the ventilator of this invention and outdoor, and in ventilator, also only arrange a swingable centrifugal fan, therefore, ventilator overall volume of the present invention can be made to reduce, structure is simple, and is convenient to installation.Meanwhile, owing to being provided with filter and the 3rd opening in the fresh air ventilator of this invention, therefore, purified treatment can be carried out to entering indoor air; And ventilator of the present invention can realize indoor and outdoor ventilation and indoor air purification two kinds of functions on a ventilator simultaneously.
Although this mode makes a ventilator can realize indoor and outdoor ventilation and indoor air purification two kinds of functions simultaneously, indoor heat/cold loss of energy when can not reduce ventilation, meanwhile, can not prevent CO concentration over-standard.
