Abstract
The utility model mainly discloses a fresh air fan control device in a central air conditioning central control system, which comprises the following components: a central air conditioning central control system, a fresh air electric air valve and an indoor carbon dioxide concentration sensor. The indoor carbon dioxide concentration sensor is provided at the indoor space for detecting carbon dioxide concentration at the indoor space, and furthermore transmits an indoor carbon dioxide concentration signal to the central air conditioning central control system. The fresh air electric air valve is equipped at a fresh air opening of the fresh air fan, and is connected with a control end of the central air conditioning central control system. The fresh air fan control device in the central air conditioning central control system has the following functions: automatically adjusting operation state according to the carbon dioxide concentration at the indoor space, improving indoor air quality and ensuring human health.
Description
Technical field
The utility model relates to the central air-conditioning technology, especially with newly fan controller is relevant in a kind of central air-conditioning centralized control system.
Background technology
New blower fan in the central air-conditioning is the terminal wherein a kind of equipment of central air-conditioning; Chilled water or hot water are transported to through the central air-conditioning pipe-line system and carry out heat exchange in the new fan coil, and the outdoor fresh air unification that will be handled by new blower fan wind pipe again is transported in each zone.
The general main fresh wind port that comprises that coil pipe, blower fan and junction chamber are outer in the new blower fan, the recirculated water of central air-conditioning are through coil pipe, and the outdoor fresh air that will be handled by blower fan is then delivered to indoor each zone and used.When meeting the requirements at outdoor environment, and temperature reaches setting value, and the air-conditioning system recirculated water in the then new blower fan stops, and directly opens fresh wind port, introduces outside new wind, is room temperature lowering, thereby realizes filtering the purpose of central air-conditioning energy in season.
And come into operation and test shows according to actual now, the terminal operating position of central air-conditioning is in dynamic change always, and the standard key of indoor air quality is seen gas concentration lwevel.Show that according to hygiene department's research the room air gas concentration lwevel was at 0.07% o'clock, human body sensory is good; The room air gas concentration lwevel is at 0.10% o'clock, and people hang up one's hat so indoor, will feel sick, lassitude, in addition unhealthful; The room air gas concentration lwevel was at 0.20% o'clock, and indoor sanitary condition obviously worsens.And the central air-conditioning use can cause indoor air to flow fast, and the room air gas concentration lwevel can make room air circulate with extraneous so need regularly introduce new wind than higher.And the new blower fan current operating mode of introducing new wind is more single, exist one open standard-sized sheet situation, can't make corresponding change according to indoor actual conditions, and VMC has accounted for about 30% at the energy consumption of whole central air conditioner system, energy consumption is huge.Simultaneously, under the prerequisite of not destroying IAQ, for realizing energy-conservation purpose.So the inventor under the structure of existing central air-conditioning, designs a kind of control device of new blower fan, this case produces thus.
The utility model content
The utility model main purpose is to provide in a kind of central air-conditioning centralized control system new fan controller, realizes that new blower fan can regulate duty automatically according to indoor sanitary condition, improves IAQ, ensures health, realizes energy-conservation purpose.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
New fan controller in the central air-conditioning centralized control system comprises central air-conditioning centralized control system, new blower fan Electric air valve, indoor carbon dioxide concentration sensor; The indoor carbon dioxide concentration sensor is positioned at indoor sensing chamber gas concentration lwevel, and concentration signal is sent in the central air-conditioning centralized control system; New blower fan electric vent control valve is installed on the fresh wind port of new blower fan, is connected the control end of central air-conditioning centralized control system.
Described central air-conditioning centralized control system inside is provided with the concentration initial value in advance.
After adopting such scheme; The utility model can be grasped indoor concentration situation, when indoor concentration reaches the concentration initial value that presets according to the detected indoor concentration of concentration sensor; Open size through central air-conditioning centralized control system control Electric air valve; Make new blower fan introduce new wind from the outside, the air of indoor muddiness is circulated, in time reduce gas concentration lwevel.
Description of drawings
Fig. 1 is the utility model preferred embodiment structural representation;
Fig. 2 is the electrical control module diagram of the utility model preferred embodiment.
The specific embodiment
In conjunction with accompanying drawing, preferred embodiment explains further details to the utility model.
Like Fig. 1, shown in Figure 2, the parts that the utility model preferred embodiment is mainly concerned with comprise central air-conditioning centralized control system 1, indoor carbon dioxide concentration sensor 2, new blower fan 4.
Central air-conditioning centralized control system 1 can adopt original control system in the central air-conditioning, and its internal structure is an equipment commonly used in the industry, does not do here and gives unnecessary details.
New blower fan 4 is exactly the wherein a kind of end-equipment in the central air-conditioning, mainly comprises coil pipe 41, blower fan 42 and fresh wind port 47.Coil pipe 41 has new Fan pipeline system's return pipe 43 and new Fan pipeline system water inlet pipe 44, and blower fan 42 comprises air outlet 45.The recirculated water of central air-conditioning is through the driving of circulation-water pump electric machine, from return pipe 43 inputs of new Fan pipeline system, from water inlet pipe 44 outputs of new Fan pipeline system.The wind regime that blower fan in the fan section 42 will pass through after the coil pipe heat exchange is seen off from air outlet 45.The external port of fresh wind port 5 is to reveal to put outdoor, and the fresh air of outside is incorporated into the new blower fan 4 from outdoor.Electric air valve 3 is installed in fresh wind port 47, is connected on the control output end of central air-conditioning centralized control system 1.
Indoor carbon dioxide concentration sensor 2 is to belong to the gas concentration lwevel sensor, is mounted on indoorly, and gas concentration lwevel state in the sensing chamber constantly, and formation concentration signal is sent on the central air-conditioning centralized control system 1.Central air-conditioning centralized control system 1 inside preestablishes the initial value of concentration, and detected actual indoor carbon dioxide concentration and initial value are done comparison, greater than initial value, then through the 3 unlatching work of central air-conditioning centralized control system 1 control Electric air valve.
Electric air valve 3 can have been realized the level adjusting in the utility model.Detected gas concentration lwevel is greater than 0.04% in the present embodiment, and smaller or equal to 0.05% o'clock, Electric air valve 3 was opened the state 25%; Gas concentration lwevel is greater than 0.05%, and smaller or equal to 0.06% o'clock, Electric air valve 3 was opened the state 50%; Gas concentration lwevel is greater than 0.06%, and smaller or equal to 0.07% o'clock, Electric air valve 3 was opened the state 75%; Gas concentration lwevel was greater than 0.07% o'clock, and Electric air valve 3 is opened the state 100%.
The utility model has been realized coming the state of Electric air valve 3 in the new blower fan of flexible according to terminal indoor carbon dioxide concentration situation, guarantees IAQ.The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
