The system comprises a constant-temperature water tank, an electric three-way valve, a three-way valve, a water pump, a frequency converter, an air filtering section, a surface cooler, a heater, a humidifier and a fan, wherein the outlet of the constant-temperature water tank is connected with the electric three-way valve, the water pump, the surface cooler, the three-way valve and the inlet of the constant-temperature water tank in sequence; the outlet of the three-way valve is connected with the inlet of the electric three-way valve; the frequency converter is connected with the signal input end of the water pump; and the air filtering section, the surface cooler, the heater, the humidifier and the fan are connected in sequence. The flow and temperature of chilled water entering the surface cooler are regulated, so that the temperature or humidity of air can be ensured to directly meet the air supply requirement during cooling and dehumidifying treatment; and in combined work with the assistance of the humidifier or the heater, quick stabilization and accurate regulation of target humiture are realized. The system has the characteristics of quick response, high accuracy, high stability, remarkable energy-saving effect and the like.
Description
Technical field
The present invention relates to air-conditioning system, relate in particular to a kind of constant temperature and humidity air-conditioning system that adopts unsteady flow quantitative change water-thermometer cooler.
Background technology
Constant temperature and humidity air-conditioning system is used for air themperature, humidity, cleanliness factor etc. are controlled within the scope of requirement, and it must have functions such as purification, cooling, dehumidifying, heating, humidification.Because constant temperature and humidity air-conditioning system requires than the traditional air-conditioning system strictness supply air temperature difference and rate of ventilation, and general long-term operation, so its energy consumption is bigger.How realizing that humiture accurately under the prerequisite of control, reduces system energy consumption, be numerous engineers and technicians' demand side to the problem that solves.
Traditional constant temperature and humidity air-conditioning system passes to the chilled water of lower temperature in the surface cooler, adopt the method for deciding dew-point temperature that air is carried out cool-down dehumidification.This method makes processed air themperature humidity all low excessively, need the wet compensation of the bigger heat of heater, humidifier after, just can send into and be transferred the space, therefore caused the lot of energy waste.The method that reduces this loss at present is mainly the wet independent control technology of heat, and it generally uses the adsorption and dehumidification method to handle humidity load separately; But use the air-conditioning system initial outlay of adsorption and dehumidification bigger, and be not suitable for the occasion that humiture needs accurate control.For this reason, the present invention proposes a kind of constant temperature and humidity air-conditioning system that adopts unsteady flow quantitative change water-thermometer cooler.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of constant temperature and humidity air-conditioning system that adopts unsteady flow quantitative change water-thermometer cooler is provided.
The present invention intends adopting following technical scheme to realize purpose of the present invention:
Adopt the constant temperature and humidity air-conditioning system of unsteady flow quantitative change water-thermometer cooler to comprise constant temperature water tank, electric T-shaped valve, triple valve, water pump, frequency converter, air filtration section, surface cooler, heater, humidifier and blower fan; The constant temperature water tank outlet is connected in turn with electric T-shaped valve, water pump, surface cooler, triple valve, constant temperature water tank import; The triple valve outlet is connected with the electric three passes valve inlet; Frequency converter links to each other with the water pump signal input; Air filtration section, surface cooler, heater, humidifier, blower fan connect in turn.
The present invention utilizes the Frequency Converter Control pump rotary speed, regulates the chilled-water flow that enters surface cooler; Utilize the ratio of electric T-shaped valve control table cooler backwater and water tank water outlet, regulate the chilled water temperature that enters surface cooler, make surface cooler the temperature or the humidity of air directly can be handled ventilation state.Utilize the further cooperating of humidifier or heater, realize the fast and stable of target humiture, accurately control, reduced the energy compensating loss in the air handling process.The converting operation of water pump has further reduced the operating energy consumption of system.It is fast that the present invention has a response, precision height, good stability, characteristics such as energy-saving effect is obvious.
Description of drawings
Accompanying drawing is the structural representation that adopts the constant temperature and humidity air-conditioning system of unsteady flow quantitative change water-thermometer cooler;
Among the figure: constant temperature water tank 1, electric T-shaped valve 2, triple valve 3, water pump 4, frequency converter 5, air filtration section 6, surface cooler 7, heater 8, humidifier 9, blower fan 10.
The specific embodiment
As shown in drawings, adopt the constant temperature and humidity air-conditioning system of unsteady flow quantitative change water-thermometer cooler to comprise constant temperature water tank 1, electric T-shaped valve 2, triple valve 3, water pump 4, frequency converter 5, air filtration section 6, surface cooler 7, heater 8, humidifier 9 and blower fan 10; Constant temperature water tank 1 outlet is connected in turn with electric T-shaped valve 2, water pump 4, surface cooler 7, triple valve 3, constant temperature water tank 1 import; Triple valve 3 outlets are connected with electric T-shaped valve 2 inlets; Frequency converter 5 links to each other with water pump 4 signal input parts; Air filtration section 6, surface cooler 7, heater 8, humidifier 9, blower fan 10 connect in turn.
Constant temperature water tank 1 provides temperature fluctuation less chilled water for system.
The ratio of electric T-shaped valve 2 control table coolers, 7 backwater and constant temperature water tank 1 water outlet is regulated the chilled water temperature that enters surface cooler.
Operation principle of the present invention is: it is preceding through an electric T-shaped valve and a variable frequency pump that chilled water enters surface cooler.Frequency converter is regulated by the control pump rotary speed and is entered the chilled-water flow of surface cooler, thereby influences the heat exchange amount, regulates the control air themperature by dynamic chilled-water flow; Electric T-shaped valve returns a certain amount of surface cooler backwater to be mixed with chilled water, adjusting enters the chilled water temperature of surface cooler, moisture removal is according to actual needs constantly adjusted the ratio that enters surface cooler chilled water and backwater, regulates the control air humidity by dynamic chilled water temperature.Surface cooler can directly be handled ventilation state with the temperature or the humidity of air, utilizes the further cooperating of humidifier or heater again, realizes the fast and stable of target humiture, accurately control.
