Abstract
The invention relates to an energy-conservation control method of a dehumidifying machine special for a swimming pool. The control method comprises the following steps: arranging a fresh air temperature/humidity sensor on a fresh air opening; counting a mixed parameter point according to different fresh air/returning air mixing ratios by dint of a programmable computer PLC; comparing with a blowing parameter area set by the PLC, wherein if a mixed blowing parameter point is within the blowing parameter area, a compressor does not need to be operated; if the mixed blowing parameter point is not in the blowing parameter area, the openings of an air exhaust valve, a fresh air valve and a returning air valve are regulated continuously, thus, mixed air parameters are approximate to the blowing parameter area as much as possible; and the operation time and power of the compressor are reduced. According to the benefit effect of the invention, an expensive dew point sensor is not used; outdoor fresh air is utilized completely and reasonably the operation time of a refrigeration compressor is reduced; energy resource is saved; simultaneously, indoor comfort is improved; and corrosion is reduced.
Description
One, technical field
The present invention relates to dehumidifier special for swimming pool, particularly relate to the energy-saving control method of the dehumidifier special for swimming pool that takes full advantage of outdoor new wind, the least possible operation compressor.
Two, background technology
Along with people to the attention of health with to the pursuit of high-quality life, swimming pool becomes the place of people's favor gradually, 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 simultaneously air themperature higher 1～2 ℃ than swimming pool water temperature.
Can be found out by above-mentioned data, if the air of indoor pool keeps constant temperature and humidity, Chi Shui to keep constant temperature, then Chi Shui and air exist partial pressure of water vapor poor, and Chi Shui is to the air evaporation water vapour, so indoor 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 pool dehumidifying unit, realizes simultaneously the multifunction refrigeration system that swimming pool Chi Shui is heated.
In temperature suitable period (such as excessive season) in 1 year, outdoor new wind state is better than the return air after the dehumidifying in some cases.In these above-mentioned times, return air is discharged from by intelligent ventilating system, 100% outdoor new wind (all-fresh air), perhaps the mist of a certain proportion of new wind and return air enters the dehumidifying unit by intelligent ventilating system, is sent back to the swimming pool space after the dehumidifying heating.
Return air inlet in fresh wind port, exhaust outlet, unit inside arranges respectively volume damper, 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 large, 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, only the consideration dehumidifying needs, and does not consider indoor cooling and heating load, although do not need dehumidifying in most of situation, needs to freeze or heat, and compressor still needs operation, can not realize energy-conservation purpose.
And dew point transducer is expensive, 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 now dehumidifier special for swimming pool (being called again: three integrated machines, dehumidifying heat pump), compare the tradition ventilation dehumidifying energy-conservation, but energy consumption is still larger; And adopt the minimum fresh air operation, comfortableness is not high more.
The present invention produces for addressing the above problem.
Three, summary of the invention

Technical scheme:
Unit arranges new wind-warm syndrome humidity sensor, return air Temperature Humidity Sensor, mixing wind-warm syndrome humidity sensor, air-supply Temperature Humidity Sensor, respectively the humiture of the outer new wind of measuring chamber, return air humiture, mix wind-warm syndrome humidity, air-supply humiture, mark each point, and obtain respectively the enthalpy of outdoor new wind, the enthalpy of return air, the enthalpy of mixing wind, the enthalpy of air-supply at psychrometric chart according to this value; Calculate the enthalpy of room air according to indoor target component, but and determine 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 namely indoor target component point is regional for indoor target component; Then, air supply parameter point is the air supply parameter zone.
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 the refrigeration system such as compressor does not need operation just can satisfy the room parameter requirement, the saving 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 mixing wind parameter point the most regional near the air supply parameter of needs, determine the aperture of new air-valve, exhaust valve, air returning valve, control resh air requirement, exhaust air rate, 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 invention has the beneficial effects as follows: 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 simultaneously indoor comfort, reduce corrosion.
