Abstract

The invention discloses a constant temperature and humidity system, and particularly relates to a constant temperature system which is used for carrying out constant humidity control by utilizing waste heat of constant temperature control. The constant temperature and humidity system comprises a water pump, a dividing wall type heat exchanger, a humidifier, a master controller, a temperature sensor and a humidity sensor. According to the constant temperature and humidity system disclosed by the invention, the mutual influence of temperature and humidity is considered, and the phenomenon that humidity control is affected while the requirement on temperature control is met is avoided; water which is generated by temperature control and subjected to heat exchange is used as a working medium of the humidifier, the time of adding the medium in the humidifier is reduced while the water resource is saved, and the working efficiency of the humidifier is increased.

Description

Constant temperature and humidity system

Technical field

The invention discloses constant temperature and humidity system, especially a kind of constant temperature system that utilizes thermostatically controlled waste heat to carry out constant humidity control.

Background technology

Keep the workshop constant temperature and humidity most important for the workshop normal operation.Temperature is controlled many employings and is realized the control of circuit with the control circuit of temperature controller, relay, but the circuit devcie cost is higher.And the temperature of carrying out after environment temperature transfinites control is attended by the steam generation more, the generation of steam certainly will affect ambient humidity.Visible, existing constant temperature and humidity control method is separated control by temperature and humidity, has ignored influencing each other between temperature and humidity, and the present invention aims to provide the interactional constant temperature and humidity system of a kind of consideration temperature humidity.

Summary of the invention

Technical problem to be solved by this invention is for the deficiency of above-mentioned background technology, and constant temperature and humidity system is provided.

The present invention adopts following technical scheme for achieving the above object:

Constant temperature and humidity system, comprise water pump, recuperative heat exchanger, humidifier, master controller, temperature sensor, humidity sensor; Wherein,

Described humidity temperature pickup output, humidity sensor output connect respectively master controller;

Described water pump medium inlet is connected with water tank, and control port is connected with described master controller;

Described recuperative heat exchanger, the first entrance is connected with described water pump media outlet, and the first outlet is connected with described humidifier medium inlet, and the second entrance advances air, and the air after heat exchange is processed is got rid of in the second outlet;

Described humidifier control port is connected with described master controller.

In described constant temperature and humidity system, recuperative heat exchanger the first outlet is connected with described water tank.

In described constant temperature and humidity system, stating temperature sensor is AD590 temperature sensor or LM335 temperature sensor.

In described constant temperature and humidity system, humidity sensor is the HS15P humidity sensor.

The present invention adopts technique scheme, has following beneficial effect: considering influencing each other of temperature and humidity, avoiding affecting humidity and control when satisfied temperature is controlled requirement; The water that temperature is controlled to the process heat exchange produced, as the humidifier working media, has reduced humidifier and has added the medium time in the time of saving water resource, improved the humidifier operating efficiency.

The accompanying drawing explanation

Fig. 1 is the constant temperature and humidity system block diagram.

The specific embodiment

Technical scheme below in conjunction with accompanying drawing to invention is elaborated:

Constant temperature and humidity system as shown in Figure 1, comprise water pump, recuperative heat exchanger, humidifier, master controller, temperature sensor, humidity sensor.Humidity temperature pickup output, humidity sensor output connect respectively master controller.The water pump medium inlet is connected with water tank, and control port is connected with described master controller.Recuperative heat exchanger, the first entrance is connected with described water pump media outlet, and the first outlet is connected with described humidifier medium inlet, and the second entrance advances air, and the air after heat exchange is processed is got rid of in the second outlet.The humidifier control port is connected with described master controller.Recuperative heat exchanger the first outlet is connected with described water tank.

Temperature sensor is AD590 temperature sensor or LM335 temperature sensor.Humidity sensor is the HS15P humidity sensor.

Temperature sensor transfers to master controller by the temperature signal recorded; Master controller sends the control signal of startup to water pump in limited time on temperature is super, and water pump pumps into recuperative heat exchanger by the water in water tank; Enter the air of recuperative heat exchanger through with water, carrying out heat exchange, recuperative heat exchanger is got rid of the air through heat exchange process, the water of process heat exchange; The humidity information that humidity sensor records transfers to master controller; Master controller sends working signal to humidifier when humidity surpasses top limit of humidity; Humidifier, under the driving of working signal, is started working with the water level medium through heat exchange of recuperative heat exchanger output.The medium demand needed in view of humidifier is less, and the water through heat exchange of recuperative heat exchanger output is returned to water tank.

In sum, the constant temperature and humidity system the present invention relates to is being considered influencing each other of temperature and humidity, has avoided affecting humidity and control when satisfied temperature is controlled requirement; The water that temperature is controlled to the process heat exchange produced, as the humidifier working media, has reduced humidifier and has added the medium time in the time of saving water resource, improved the humidifier operating efficiency.
