Description
Technical Field
The invention relates to an air conditioning unit, in particular to a full-performance air conditioning integration unit, an air channel structure thereof and a compatible system function process.
Background
With the continuous rising of air temperature, the exposure of PM2.5 air pollution, the serious indoor air pollution, the improvement of the sealing performance and the heat preservation performance of a building, the urgent requirements of human existence on the control of air quality and the construction of human habitability air environment, the national control of indoor air pollution and the energy saving and indoor ventilation problems of the building are paid attention to, a series of national standards are developed successively, the requirement that fresh air must be introduced into a civil building is met, and meanwhile, the air quality of the fresh air, such as humidity, temperature, cleanliness, freshness and the like, is integrated to meet the requirements of the human habitability environment conditions.
The introduction of fresh air causes fluctuation of indoor temperature, humidity and cleanliness, and new high-temperature pollution, low-temperature pollution, wet pollution, dry pollution, PM2.5 and other harmful pollutants are formed. The independent heat pump air conditioner, dehumidifier, humidifier and air purifier can not meet the requirement of removing various pollution sources caused by the introduction of fresh air, and the air conditioner can greatly increase energy consumption; the problems of high thermal pollution, dehumidification water discharge and high energy consumption can be caused by refrigeration and dehumidification, and high energy consumption is caused by water pollution generation and humidification water gasification of the humidifier; the high wind resistance of the HEPA purifier can greatly increase the energy consumption, and the filtering type air purifier is easy to grow mildew and breed bacteria.
Only one or several balance requirements in the air quality parameters can be achieved by using a single special device, but each single device generates new pollution or energy burden. When pollution caused by PM2.5 cannot be tolerated by human beings, a HIPA high-efficiency filter for filtering PM2.5 particulate matters is added on a fresh air fan, an air energy recovery device, an air conditioner, a fresh air dehumidifier and other equipment, so that energy load and virus and germ pollution are generated.
The conventional air conditioning units suffer from the following inevitable drawbacks:
(1) the indoor constant temperature is realized: because the energy consumption of the air conditioner is large, the air conditioner is generally carried out in a closed space, and has the auxiliary effects of three negative parts and one positive part besides constant temperature, wherein one negative part is large in energy consumption, the other negative part is used for heating to increase the indoor dryness, and no fresh air is introduced into the three negative parts; firstly, the dehumidification function is realized during refrigeration, but the temperature can be reduced during dehumidification in plum rain season, and the constant temperature requirement cannot be met at the moment.
(2) The dehumidification effect is not satisfactory: the dehumidifier has only a dehumidifying function, and the humidifier has only a humidifying function; at present, all human-living environment humidifiers almost need to be added with water manually, and after the water is stored in the humidifier for a long time, bacteria can be bred, so that the water capacity of the humidifier is not too large generally.
(3) Energy cannot be fully recovered: in the processes of refrigeration, dehumidification and heating humidification of a common air conditioner, sensible heat energy of exhausted dirty air, low-temperature sensible heat and latent gasification heat of dehumidification water cannot be recovered; because there is the energy of indoor air in the dirty wind of discharge, and introduce the new trend and also contain the energy of outdoor air, the energy difference of dirty wind and new trend forms double energy loss.
(4) Generating indoor pressure fluctuation: fresh air introduction and dirty air discharge are not adjustable, and pressure fluctuation exists; the air quantity required by the refrigerating and heating and dehumidifying and humidifying functions of the condenser of the refrigerating system is about 10 times of the fresh air quantity, the air quantity required by the dehumidifying capacity requirement of the condenser is 10 times of the exhausted sewage air quantity, and the purpose of sharing an air channel by the fresh air fan, the refrigerating and heating and the dehumidifying and humidifying cannot be realized.
(5) A source of dynamic noise is generated: the refrigeration system and the fan system of the common air conditioner, such as an independent air conditioner, a dehumidifier, a humidifier, an air energy recovery device, an air purifier and the like, have a power noise source indoors.
(6) Uneven indoor temperature: the indoor machine of the common air conditioner adopts an air circulation mode of upper inlet and lower outlet, only a small amount of inlet and outlet air is short-circuited during refrigeration, but hot air can rise during heating, the short circuit of the inlet and outlet air is easily caused, the treated indoor air only circularly flows at the inlet and outlet air ports of the inner machine, and the indoor temperature distribution is extremely uneven.
(7) The purification system technology falls behind: the common air conditioner adopts an HEPA filtering type air purifier, and has weak sterilization capability, large wind resistance, short service life and non-renewable sterilization capability; the heat pollution of the dehumidifier and the harmful pollution to people generated by the sterilization and disinfection equipment can be used only under the condition of forcing people to live.
(8) The production cost is high, the ① product purchase cost is high, the ② power consumption is large, and the ③ water consumption is large.
In summary, the prior art cannot avoid the contradiction between the fresh air and the purified air flow and the air flow required by the heat exchanger of the dehumidification and refrigeration system, the air flow is greatly different, and the compatibility of the oxygen supply fresh air flow, the sewage discharge air flow, the refrigeration dehumidification air flow and the heating humidification air flow is poor.
Disclosure of Invention
The invention aims to solve the defects of high energy consumption and high investment of combined use of three constant engineering equipment in a room by aiming at the full combination of a heat pump air conditioner, a dehumidifier, a humidifier, a fresh air fan, an air energy recovery device and an air purifier of the three constant engineering equipment in the current market, and provides a full-performance air conditioner integration unit which can achieve the purposes of constant temperature, constant humidity, constant pressure, constant silence, constant uniformity, constant cleanness and energy recovery.
