Abstract
The utility model discloses an energy-saving control structure of a dehumidifier special for a swimming pool. The energy-saving control structure of the dehumidifier is characterized in that a fresh air opening is provided with a fresh air temperature and humidity sensor, a programmable logic controller (PLC) calculates parameter points after fresh air and return air are mixed according to different mixing ratios, and the parameter points are compared with an air-supply parameter region set by the PLC. If the air-supply parameter points are in the air-supply parameter region after mixing, a compressor does not need to run; and if the air-supply parameter points are not in the air-supply parameter region after mixing, an opening degree of an exhaust valve, an opening degree of a fresh air valve and an opening degree of a return air valve are adjusted continuously so that mixed-air parameters are close to the air-supply parameter region as far as possible, and running time and power of the compressor are reduced. The energy-saving control structure of the dehumidifier has the advantages that an expensive dew point sensor is not adopted, outdoor fresh air is fully and reasonably utilized, the running time of the refrigeration compressor is reduced, the energy is saved, simultaneously indoor comfortableness is improved, and corrosion is reduced.
Description
One, technical field
The utility model relates to the special-purpose dehumidifier of swimming pool, particularly relates to the Energy Saving Control structure of the special-purpose dehumidifier of swimming pool that makes full use of outdoor new wind, the least possible operation compressor.
Two, background technology
Along with people's is to the attention of health with to the pursuit of high-quality life, and swimming pool becomes the place of people's favor gradually, and comfortable, healthy, energy-conservation, friendly type swimming pool arises at the historic moment.
The air conditioning parameter of indoor swimming pool is generally got as follows:
Require air themperature higher 1～2 ℃ simultaneously than swimming pool water temperature.
Can be found out that by above-mentioned data if the air of indoor swimming pool keeps constant temperature and humidity, Chi Shui to keep constant temperature, then Chi Shui and air exist partial pressure of water vapor poor, Chi Shui is to the air evaporation water vapour, and therefore indoor swimming pool needs to dehumidify the whole year.
It is a kind ofly both room air to be heated, cool off, dehumidifies that air dewetting, air constant temperature, Chi Shui heat three-in-one indoor swimming pool dehumidifying unit, realizes the multifunction refrigeration system that swimming pool Chi Shui is heated simultaneously.
In the period (like excessive season) that temperature suits in 1 year, outdoor in some cases new wind state is better than the return air after the dehumidifying.In these above-mentioned times, return air is discharged from through intelligent ventilating system, 100% outdoor new wind (brand-new wind), and the mist of perhaps a certain proportion of new wind and return air gets into the dehumidifying unit through intelligent ventilating system, is sent back to the swimming pool space after the dehumidifying heating.
At fresh wind port, exhaust outlet, the inner return air inlet of unit volume damper is set respectively; At fresh wind port new wind dew point transducer is set; When the air dew point after dew point that this dew point transducer detects outdoor new wind is than the dehumidifier dehumidifying is low; New air-valve, air returning valve aperture become big, increase resh air requirement, exhaust air rate.When outdoor new wind can satisfy indoor dehumidifying fully and requires, compressor did not move, and saved the energy.
But adopt the new wind sensor control of above-mentioned dew point resh air requirement, a consideration dehumidifying needs, and does not consider indoor cooling and heating load, though do not need dehumidifying under most of situation, needs to freeze or heat, and compressor still needs to move, and can not realize purpose of energy saving.
And dew point transducer costs an arm and a leg, and investment of equipment is high.
In addition, the evaporation of constant indoor temperature swimming pool pond water surface can make room air contain a large amount of chlorine ammonia/haloforms, and serious harm people's health is also corroded building.
For addressing the above problem, traditional swimming pool adopts ventilation drying, replaces chloride air, and power consumption greatly; Adopt the special-purpose dehumidifier of swimming pool (being called again: three integrated machines, dehumidifying heat pump) now, it is energy-conservation to compare the tradition ventilation dehumidifying, but energy consumption is still bigger; And adopt the minimum fresh air operation, comfortableness is not high more.
The utility model is to produce for addressing the above problem.
Three, summary of the invention

Technical scheme;
Unit is separately installed with new wind-warm syndrome humidity sensor, return air Temperature Humidity Sensor, mixing wind-warm syndrome humidity sensor, air-supply Temperature Humidity Sensor at fresh wind port, return air inlet, new return air hybrid hydrostatic case, air outlet; Gather outdoor new wind-warm syndrome humidity, return air humiture respectively, new return air mixes the numerical value of humiture, air-supply humiture, on psychrometric chart, mark each point, and obtain the enthalpy of outdoor new wind, the enthalpy of return air, the enthalpy of mixing wind, the enthalpy of air-supply respectively according to this value; Calculate the enthalpy of room air according to indoor target component, but and confirm receiving chamber's internal object parameter region; The air supply parameter zone that programmable controller PLC adjusts out with PID;
On the air psychrometric chart, indoor target component point is (N), establishes float ± 1 ℃, humidity of temperature and floats and ± 5% be acceptable target temperature humidity range, and promptly indoor target component point is regional for indoor target component; Then, air supply parameter point is the air supply parameter zone.
Between fresh wind port place, exhaust outlet place, new return air hybrid hydrostatic case and air draft plenum chamber, be separately installed with new air-valve, exhaust valve, air returning valve, these 3 air-valves are the air quantity ratio adjusting valve, by its aperture of programmable controller PLC control.Constantly regulate the aperture of new air-valve, exhaust valve, air returning valve; Make mixing wind parameter the most regional with the air supply parameter that PID adjusts out near programmable controller PLC; If mix the wind parameter point in this air supply parameter zone; Then refrigeration system such as compressor need not moved and just can satisfy the room parameter requirement, saves the energy;
If mix the wind parameter point not in this air supply parameter zone; Then calculate best new wind ratio according to above enthalpy; Make and mix the wind parameter point, confirm the aperture of new air-valve, exhaust valve, air returning valve, control resh air requirement, exhaust air rate near the air supply parameter zone that needs; Section, power are minimum to make compressor operating time, save the energy.
According to indoor occupant needs, the indoor chloride air needs of displacement, establish the minimum fresh air ratio; When the new wind ratio that calculates is worth less than this, carry out by this value.
Beneficial effect:
The beneficial effect of the utility model is: do not adopt expensive dew point transducer, reduce initial cost; Adopt temperature, the humidity of the new wind of Temperature Humidity Sensor composite measurement, not only considered the indoor humidity load of new wind burden, but also considered that new wind bears indoor cooling and heating load, fully, rationally utilize outdoor new wind, reduce refrigeration compressor running time, save the energy; Improve indoor comfort simultaneously, reduce corrosion.
