Abstract
The utility model relates to a constant-temperature constant-humidity air conditioning set mainly used for blowing and cooling in the whole chemical fiber springing course. A heating section and a cooling section of the prior air conditioner are reduced into a heat exchanger. The old water or hot water is supplied by the heat exchanger in different time periods by using the functions of either generating cold water or hot water with the cold and hot water unit according to the control requirements so as to control the constant temperature and constant humidity of the outlet wind of the air conditioner. Compared with the electric-heating or steam-heating air conditioners, the utility model saves more energy, protects the environment, which can lower the manufacturing cost and operation expenses for the air conditioner.
Description
Affiliated technical field
The utility model relates to a kind of thermostatic and humidistatic air conditioning unit group, especially the blowing air-conditioning unit of chemical fibre spinning cooling usefulness.
Background technology
At present, general thermostatic and humidistatic air conditioning unit group is in order to reach the purpose that wind pushing temperature is constant, humidity is constant, and the air-conditioning unit is generally by bringing-up section, cooling section, humidifier section and send blower fan back to and fillter section is formed.Wherein the low-temperature receiver of surface cooling section provides chilled water from handpiece Water Chilling Units, and the thermal source of bringing-up section generally is electricity or steam.For electrical heating, energy resource consumption is big (Energy Efficiency Ratio is less than 1), and Steam Heating will dispose steam boiler, and cost is high and can bring corresponding environmental issue.
Summary of the invention
At existing thermostatic and humidistatic air conditioning unit group, the utility model provides a kind of new air-conditioning preparation assembled scheme, and this scheme not only can reduce the manufacturing cost of air-conditioning, can also energy savings, reduce the operating cost of air-conditioning greatly.
The technical scheme that its technical problem that solves the utility model adopts is: for the air-conditioning unit of deciding dew point control, cancel first bringing-up section, provide hot and cold water with hot and cold water unit his-and-hers watches cooler, the function of surface cooler has just become a heat exchanger like this, thereby reaches the dual purpose that air is heated or cools off.And the surface cooling section and first bringing-up section are united two into one, saved a functional section of air-conditioning.Air-conditioning unit to non-dew point control provides hot and cold water with hot and cold water unit his-and-hers watches cooler, and spring, autumn, three seasons of winter can be saved out secondary heater, have reduced energy consumption.For the heater of the air-conditioning of non-dew point control and the secondary heater of decide the air-conditioning unit that dew point controls, also can provide thermal source with water chiller/heater.
The beneficial effects of the utility model are, can make the air-conditioning unit of deciding dew point control save a functional section, reduce the manufacturing cost of air-conditioning, reduce the floor space of air-conditioning; Owing to adopt the hot and cold water unit that Cooling and Heat Source is provided, with the Steam Heating ratio, need not steam boiler simultaneously, with the electrical heating ratio, its Energy Efficiency Ratio can reach more than 3, saves the energy and surpasses 60%.

The specific embodiment
The air-conditioning unit of deciding dew point control to routine, its design such as Fig. 2, surface cooler is designed to a heat exchanger, and be connected with the hot and cold water unit, when adopting humidification for spray humidification scheme, if the air intake enthalpy after mixing wind is less than the enthalpy of setting dew point, maybe when adopting humidification to be the steam humidification scheme, if the EAT after mixing wind is less than setting dew point value, this moment, air intake need heat, and hot and cold water unit heat supply water adds heat with the control of certain aperture to what this heat exchanger provided by three-way control valve, to reach behind saturated humidification the dew-point temperature of wind-warm syndrome for setting.When adopting humidification for spray humidification scheme, if the air intake enthalpy after mixing wind is greater than the enthalpy of setting dew point, maybe when adopting humidification to be the steam humidification scheme, if the EAT after mixing wind is greater than setting dew point value, this moment, air intake need cool off, and hot and cold water unit cooling water is controlled the amount of cooling water that provides to this heat exchanger by three-way control valve with certain aperture, reach behind saturated humidification the dew-point temperature of wind-warm syndrome equally for setting.Again through two heat after, air-supply is the humiture for setting just in time.This moment, former primary heater was cancelled, had saved a functional section, and the machine group length reduces, and manufacturing cost reduces.
Air-conditioning unit to the non-dew point control of routine, because its humidification is controlled, when adopting humidification, generally adopt VFC (also can adopt three-way control valve control) for spray humidification scheme, when adopting humidification to be the steam humidification scheme, generally adopt control valve control.When with humidification being spray humidification scheme, generally can reach air intake enthalpy after mixing wind in spring, autumn, three seasons of winter less than the enthalpy under design temperature and the damp condition, this moment, air intake need heat, hot and cold water unit heat supply water, add heat with the control of certain aperture to what this heat exchanger provided by three-way control valve, behind the control humidification, wind-warm syndrome, rheumatism just in time are setting value; When being the steam humidification scheme with humidification, generally also can reach EAT after mixing wind in spring, autumn, three seasons of winter less than design temperature, the water capacity of air intake is less than the water capacity of setting under the humiture, this moment, air intake need heat, hot and cold water unit heat supply water, add heat with the control of certain aperture to what this heat exchanger provided by three-way control valve, behind the control humidification, wind-warm syndrome, rheumatism just in time are setting value.So just saved two and added, reduced energy consumption.During summer, air intake behind the mixed wind needs cooling dehumidification, this moment air-conditioning control model with to decide the dew point control model identical, because air intake need cool off, hot and cold water unit cooling water, by three-way control valve with the control of certain aperture to the amount of cooling water that this heat exchanger provides, reach equally through two add after, the temperature and humidity of wind-warm syndrome for setting.
