Existing three kinds of duties to the utility model are described in detail as follows:
State one: shown in Fig. 4 a-b; The integral type air-conditioning is under the user mode that normally need not renew wind (in order clearly to represent the situation of change of air inlet, will renew wind executing agency 6 is that wind deflector and wind guide tank assembly move on to outside the machine, renews wind executing agency 6 in the following state one, two and also moves on to the situation of change that machine is represented its air inlet outward); The first outdoor air inlet 1.1 is blocked in the wind deflector left side; First indoor air inlet 2.1 is opened, and the air of indoor is under the effect of blower fan, and (this heat exchanger is an evaporimeter in summer to first heat exchanger 3 of flowing through; Be condenser winter; The switching of the cross valve through air-conditioning system realizes), the cooling (summer) or (winter) after-blow that heats up are gone into indoor, reach the purpose of reductions (summer) or raising (winter) indoor temperature.Wind deflector 2 right sides are then blocked second indoor air inlet 1.4; The second outdoor air inlet 1.2 is opened; The air of outside is under the effect of blower fan, and flowing through along the air channel, (this heat exchanger is a condenser in summer to second heat exchanger 4, and be evaporimeter winter; The switching of the cross valve through air-conditioning system realizes) after, take to heat (summer) or cold (winter) outdoor.
State two: shown in Fig. 5 a-b, when specific gas (like CO
2) CO
2When sensor detects the overproof setting value of the content of indoor specific gas; Drive unit will drive wind deflector 2 and turn to respective angles and (see Fig. 5 a; Open angle is by the decision of specific gas concentration numerical value, by the action of control circuit command execution unit), this moment, a part was opened with the first outdoor air inlet 1.1 in wind deflector 2 left sides; First indoor air inlet 1.3 is blocked a part; The fresh air of outside is under the effect of blower fan, and is inboard through first heat exchanger, 3 inlet chambers, reaches the purpose of replenishing fresh air to the indoor.A part is then opened with second indoor air inlet 1.4 in wind deflector 1 right side, and the second outdoor air inlet 1.2 is blocked a part, the indoor foul air under the effect of blower fan, flow through 4 heat exchange of second heat exchanger along the air channel after, be discharged to outdoor.Under this state; Because indoor outdoor air (air themperature of outside is cool in summer and warm in winter relatively) second heat exchanger 4 of flowing through that is discharged to, the heat exchange efficiency of integral air conditioner will obviously improve; Under the constant situation of consumed power; Its refrigeration (summer) heats (winter) amount and will obviously improve, and has reclaimed major part and has renewed the cold and hot amount loss in the wind process, reaches the purpose that reduces energy loss.
State three: shown in Fig. 6 a-b, when specific gas (like CO
2) CO
2Sensor detects the indoor specific gas (like CO
2) content very high; During the value of overstepping the extreme limit, drive unit will drive wind deflector and turn to position among Fig. 6 a, and this moment, opened the first outdoor air inlet 1.1 fully in wind deflector 2 left sides; First indoor air inlet 1.3 is blocked fully; The fresh air of outside flows to the indoor through first heat exchanger 3 under the effect of blower fan, maximal rate exchange fresh air for for the indoor.Then open second indoor air inlet 1.4 fully on the wind deflector right side, the second outdoor air inlet 1.2 is blocked fully, the indoor foul air under the effect of blower fan, maximal rate flow through 4 heat exchange of second heat exchanger along the air channel after, be discharged to outdoor.Under this state; The air of second heat exchanger 4 all comes from the indoor (air themperature of relative outside owing to flow through; Cool in summer and warm in winter), integral air conditioner refrigeration (summer) heats (winter) efficient and reaches the highest, can compensate most of energy loss that causes because renewing wind.
The angle of wind deflector rotation determined to change air quantity size, the anglec of rotation is by step motor drive.Control circuit according to specific gas (like CO
2) CO
2The Data Control stepper motor of sensor can be according to the specific gas in the room air of reality (like CO
2) concentration realize automatically ventilation volume from zero to peaked step-less adjustment.When being in state for the moment, the integral type air-conditioning is the logical air-conditioning of a Daepori purely; When the state two of being in, the integral type air-conditioning is an air-conditioning, also is a cold and hot retracting device, simultaneously can carry out replenishing of fresh air to indoor; When state three, the integral type air-conditioning is in cold and hot recovery state fully, and carries out replenishing of fresh air with maximal rate to indoor.The control system can be according to indoor specific gas (like CO
2) its duty of concentration step-less adjustment, remain the fresh of room air.
It is example that the foregoing description is selected with machine through walls, the same to other integral type air-condition principles such as window machines, does not do explanation in addition.
Under the duty of refrigeration in normal summer, second heat exchanger 4 is as the condenser of air-conditioning system, and its effect is that the cold-producing medium to HTHP carries out condensation.Summer, the outdoor air temperature was higher; If when renewing wind, the room air of lower temperature second heat exchanger 4 of when discharging, flowing through is with condensation rate that obviously improves cold-producing medium and effect; Air conditioner refrigerating efficient will be largely increased; Its increase rate flow of room air of this heat exchanger that directly is decided by to flow through, so change air quantity bigger (simultaneously indoor also big more because of replenishing the loss of refrigeration capacity that fresh air causes), air conditioner refrigerating efficient is also high more; The absolute value of cold recovery is also big more, and the indoor loss of refrigeration capacity that causes because of additional fresh air is played compensating action.
Under normal winter heating duty, second heat exchanger 4 is as the evaporimeter of air-conditioning system, and its effect is the heat in the absorption chamber outer air, and the cold-producing medium of low-temp low-pressure is evaporated.Winter, the outdoor air temperature was lower; When renewing wind, the indoor air of higher temperature second heat exchanger 4 of when being discharged to the outside, flowing through is with evaporation rate that obviously improves cold-producing medium and effect; The air-conditioning heating efficiency will be largely increased; Its increase rate its flow of room air that directly is decided by to flow through, so change air quantity bigger (simultaneously indoor also big more because of replenishing the thermal loss that fresh air causes), the air-conditioning heating efficiency is also high more; The absolute value of heat recovery is also big more, and the indoor thermal loss that causes because of additional fresh air is played compensating action.
Since any cold and hot retracting device all can not 100% the cold and hot amount of losing in the wind process that will renew all reclaim; Take automatic control system; IAQ is controlled on the numerical value of setting, when IAQ is qualified, closes automatically and renew wind system; When IAQ is defective, confirm the suitable air quantity that changes according to its concrete air parameter.So just avoided a lot of ventilation units under the room air of being everlasting situation up to standard, the meaningless wind that renews, or it is excessive to change air quantity, the problem of loss indoor energy in vain.
About selecting in the air specific gas concentration parameter as the explanation of air quality parameters: the IAQ influence factor is a lot; Generally speaking; Get rid of disposable influences such as finishing, human and other vegeto-animal activities mainly can be selected CO to the influence of air quality
2Concentration is as parameter index, because the small main influences of burning such as the backlight cooperation of human or animal's breathing, plant usefulness, smoking and kitchen range can be through monitoring CO
2Concentration is used as reference value, and CO
2Concentration sensor is a mature technique, is very easy to realize.Certainly, to special circumstances, we also can select the parameter of other gas concentration as air quality, even can select multiple gases parametric synthesis fuzzy control in case of necessity, all are ripe on the engineering, do not explain in addition.
The utility model guarantee freeze, heat, on the basis of integral type air-conditioning basic function such as dehumidifying, introducing intelligence renews the wind function, through to specific gas in the room (like CO
2)) concentration data gathers automatically, intelligence accurately control renews wind executing agency, realizes the effective control to air quality in the room.Simultaneously; Through the design of special air channel, the flow direction of air is controlled, make to be discharged to the flow through heat exchanger of air-conditioning of outdoor turbid air; Cold (summer) or heat (winter) are reclaimed; Significantly reduce the loss of indoor cold (heat), thereby reduce the specific energy consumption of air-conditioning, reach energy-conservation purpose.The utility model is integrated in the air channel of integral type air-conditioning, and realizes Based Intelligent Control, stepless automatic adjusting, has not only improved and guarantees IAQ but also reduce the specific energy consumption of air-conditioning.
