Abstract

The utility model relates to an air-conditioning unit with the temperature detection function. The air-conditioning unit includes a mixing section, a primary filtering section, a refrigerating section, a heating section and a fan section, which are sequentially assembled and communicated, wherein a temperature sensor is installed on an inner wall of a connecting part of a backwind pipe and the mixing section; another temperature sensor is installed on an inner wall of a connecting part of an air supply pipe and the fan section; the output ends of the two temperature sensors are connected with a temperature controller; a normally closed contact of the temperature controller is connected in series with a coil of a relay; and a normally closed contact of the relay is connected in series with a coil of an AC contactor. In the air-conditioning unit, when temperature in the backwind pipe reaches a set value, that is to say, the temperature in a production workshop meets the requirement, the heating section loses power and stops operating, so that the temperature of the production workshop can be automatically controlled; and when temperature in the air supply pipe reaches a danger value, that is to say, combustion is likely to be caused, the heating section loses power and stops operating, so that the safety of equipment is guaranteed.

Description

Air-conditioning unit with temperature detecting function

Technical field

The utility model belongs to air-conditioning unit control technology field, especially a kind of air-conditioning unit with temperature detecting function.

Background technology

In the pharmaceutical manufacturing process, the humidity of workshop, temperature must keep within the specific limits, to guarantee the quality of medicine.Commonly used carry out humidity, thermoregulator equipment is the air-conditioning unit; The structure of this air-conditioning unit is as shown in Figure 1: comprise mixer 6, initial effect filtering section 7, refrigerating section 8, bringing-up section 9 and fan section 10; Mixer is communicated with workshop through backwind tube 4; Fan section is communicated with workshop through ajutage 12, and whether the work of each section is controlled by switch cubicle 13 built-in series switch.

When operating personnel go to work, open A.C. contactor KM and circuit breaker Q F, the bringing-up section power supply gets electric, the cold wind heating that the resistance wire heating of bringing-up section will be blown over; Be blown into workshop through fan section, again by the backwind tube circulation, when next; Operating personnel close A.C. contactor KM and circuit breaker Q F, make bringing-up section power supply dead electricity, but in the said process; The control of bringing-up section is accomplished by manual work fully, and is promptly inconvenient, also dangerous.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, and a kind of rational in infrastructure, automatic air-conditioning unit of controlling with temperature detecting function of temperature is provided.

A kind of air-conditioning unit with temperature detecting function; Comprise assembling successively and the mixer, initial effect filtering section, refrigerating section, bringing-up section and the fan section that are communicated with; Backwind tube is installed on the mixer; Ajutage is installed on the fan section, and the bringing-up section power supply is connected in series and is connected civil power behind A.C. contactor and the breaker, it is characterized in that: on the junction inwall of said backwind tube and mixer temperature sensor is installed; Another temperature sensor is installed on the junction inwall of said ajutage and fan section; The output of these two temperature sensors all connects a temperature controller, the be connected in series coil of A.C. contactor of the connect coil of a relay of a normally-closed contact of this temperature controller, the normally-closed contact of this relay.

And said two temperature sensors are installed in the inwall of backwind tube and ajutage respectively through a support.

The advantage and the good effect of the utility model are:

In the utility model; On the inwall of the junction of backwind tube and mixer, temperature sensor is installed; Another temperature sensor is installed on the inwall of the junction of ajutage and fan section; The output of these two temperature sensors is transported to temperature signal in the temperature controller, is realized the break-make of A.C. contactor by the relay of temperature controller control.When the temperature in the backwind tube reaches setting value; Mean that the temperature in the workshop meets the requirements, the bringing-up section dead electricity quits work, and has realized the workshop temperature auto control thus; When the temperature in the ajutage reaches dangerous values; Mean to cause burning, the bringing-up section dead electricity quits work, and guarantees the safety of equipment thus.

The specific embodiment

Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.

A kind of air-conditioning unit with temperature detecting function; Shown in Fig. 1～2; Comprise assembling successively and the mixer 6, initial effect filtering section 7, refrigerating section 8, bringing-up section 9 and the fan section 10 that are communicated with; Backwind tube 4 is installed on the mixer, ajutage 12 is installed on the fan section, backwind tube and ajutage outer wall all coat installs heat-insulation layer 1; Bringing-up section power supplys in the switch cubicle 13 are connected in series and are connected civil power behind A.C. contactor KM and the circuit breaker Q F; The innovation of the utility model is: on junction 5 inwalls of backwind tube and mixer return air temperature sensor 3 is installed, wind pushing temperature sensor 11 is installed on the junction inwall of ajutage and fan section, the output of return air temperature sensor and supply air sensor all is connected the temperature controller of being adorned on the switch cubicle 14; The be connected in series coil KMXQ of A.C. contactor KM of the connect coil JK of a relay of a normally-closed contact TKCB of this temperature controller, the normally-closed contact JKCB of this relay.

Return air temperature sensor and supply air sensor are installed in the inwall of backwind tube and ajutage respectively through a support 2.

The testing process of return air temperature sensor and wind pushing temperature sensor is:

Operating personnel close A.C. contactor KM and circuit breaker Q F, and the bringing-up section power supply gets electric, the resistance wire heating of bringing-up section; Cold air is heated, and is blown into workshop through fan section, is circulated by backwind tube again; When the temperature of return air temperature sensor measurement reached the temperature of temperature controller setting, temperature controller made relay coil JK dead electricity, and the normally-closed contact JKCB of relay opens; A.C. contactor KMXQ dead electricity, A.C. contactor KM breaks off, bringing-up section power supply dead electricity; The resistance wire of bringing-up section quits work, and accomplishes temperature auto control thus.

When the temperature of wind pushing temperature sensor measurement reaches the dangerous values of temperature controller setting; Temperature controller output control signal makes relay coil JK dead electricity, and the normally-closed contact JKCB of relay opens, A.C. contactor KMXQ dead electricity; A.C. contactor KM breaks off; Bringing-up section power supply dead electricity, the resistance wire of bringing-up section quits work, and accomplishes the protection to screen pack and heat-insulation layer thus.

In the utility model; On the inwall of the junction of backwind tube and mixer, return air temperature sensor is installed; On the inwall of the junction of ajutage and fan section, wind pushing temperature sensor is installed; The output of return air temperature sensor and supply air sensor is transported to temperature signal in the temperature controller, is realized the break-make of A.C. contactor by the relay of temperature controller control.When the temperature in the backwind tube reaches setting value; Mean that the temperature in the workshop meets the requirements, the bringing-up section dead electricity quits work, and has realized the workshop temperature auto control thus; When the temperature in the ajutage reaches dangerous values; Mean to cause burning, the bringing-up section dead electricity quits work, and guarantees the safety of equipment thus.
