The moistureproof heating device for the commercial air conditioner can automatically detect humidity in an air conditioner control cabinet before the air conditioning system starts, utilizes the heater for heating dehumidification, and automatically shuts off after the air conditioner starts, thereby preventing the air conditioner from being damaged due to overhigh temperature in the air conditioner control cabinet.
Description
Technical field
The utility model belongs to the business air conditioner field, refers in particular to a kind of moistureproof heater of business air conditioner.
Background technology
Air-conditioning because there are the apparent in view temperature difference in indoor temperature and outdoor temperature, start equipment such as cabinet, frequency conversion tank and the condensation phenomenon can occur in use, and condensation combines the electric elements that meeting damages air-conditioning inside with dust, air-conditioning itself is caused certain harm.Manual operation is adopted in the air-conditioning protection against the tide of prior art more, can't realize automatic protection against the tide, when the user forgets moistureproof action, is easy to air-conditioning is damaged; Or adopt protection against the tide automatically, but its complex structure, manufacturing cost is higher.
Summary of the invention
The moistureproof heater of a kind of business air conditioner that the utility model provides, it can be before air-conditioning system starts, automatically detect air-conditioning switch board humidity inside, utilize the heater heating and dehumidification, and behind starting of air conditioner, automatically close, prevent that the temperature in the air-conditioning switch board is too high, air-conditioning is caused damage.
The utility model is achieved in that
A kind of moistureproof heater of business air conditioner, it comprises and is used to the cooling fan relay controlling the main switch of air-conditioning system and be used to control this blower fan, it also comprises the heater that connects successively, the humidity sensor that adds thermal time delay switch and be used for detection system humidity, this adds the heat time heating time that thermal time delay switch is controlled this heater, in addition, the major loop relay and the heater relay that also comprise anti-shake delay switch, interlocking, anti-shake delay switch are connected between the normally-closed contact of the main switch of air-conditioning system and major loop relay.
Preferred this humidity sensor is the switching mode humidity sensor.
When the main switch closure, this heat radiation wind relay adhesive, anti-shake delay switch and add thermal time delay switch work, humidity sensor detects the humidity in the switch board, if in the time range of anti-shake delay switch, when surpassing default humidity, this switching mode humidity sensor adhesive, add the electrothermal relay adhesive, then heating circuit is communicated with, and begins switch board is heated.
For when reaching moistureproof purpose, it is too high to prevent to control in-cabinet temperature, after reaching the delay time of delay switch, adds thermal time delay switch and disconnects, and add electrothermal relay and disconnect, the adhesive of major loop relay, the work of air-conditioning major loop, air-conditioning system begins operate as normal.Heater is avoided working simultaneously with air-conditioning system, thereby avoids temperature in the air-conditioning switch board too high and electric equipment is damaged.
Preferably, this major loop relay and heater relay are that interlocking connects.
Alternative is that this heater is arranged at the air outlet and/or the protected device periphery of this blower fan.
The utility model has following beneficial effect with respect to prior art:
The heater of the utility model business air conditioner can effectively improve the moist condensation volume of air-conditioning switch board phenomenon, improves the reliability of air-conditioning.
Description of drawings
Fig. 1 is the circuit diagram of the moistureproof heater of the utility model business air conditioner;
Fig. 2 is the scheme of installation of the moistureproof heater of the utility model business air conditioner.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figure 1.The moistureproof heater of the utility model business air conditioner, it includes the main switch K that is used to control air-conditioning system
1, and be used to control the cooling fan relay K M of this blower fan 1
2, it also comprises successively the heater 2 that connects, adds thermal time delay switch KT
1, and be used for the switching mode humidity sensor MS of detection system humidity, this adds thermal time delay switch KT
1Control this heater 2, in addition, also comprise anti-shake delay switch KT
2, interlocking major loop relay K M
1And heater relay KM
3, this major loop relay K M
1With heater relay KM
3For interlocking connects, this anti-shake delay switch KT
2Be connected in the main switch K of air-conditioning system
1With major loop relay K M
1Normally-closed contact between.
As main switch K
1Closure, this heat radiation wind relay K M
2Adhesive, anti-shake delay switch KT
2With add thermal time delay switch KT
1Work, switching mode humidity sensor MS detects the humidity in the switch board, if at anti-shake delay switch KT
2The Preset Time scope in, when switching mode humidity sensor MS detects humidity and surpasses default humidity, this switching mode humidity sensor MS adhesive, this heating relay K M
3Adhesive, then heating circuit is communicated with, and begins switch board is heated; If at anti-shake delay switch KT
2The Preset Time scope in, when switching mode humidity sensor MS detected humidity and do not have to surpass default humidity, switching mode humidity sensor MS kept off-state, then at anti-shake delay switch KT
2After time-delay was finished, air-conditioning system then began operate as normal.
For when reaching moistureproof purpose, it is too high to prevent to control in-cabinet temperature, adds thermal time delay switch KT reaching
1Default delay time after, add thermal time delay switch KT
1Disconnect heating relay K M
3Disconnect major loop relay K M
1Adhesive, the work of air-conditioning major loop, air-conditioning system begins operate as normal.Heater 2 is avoided working simultaneously with air-conditioning system, thereby avoids temperature in the air-conditioning switch board too high and electric equipment is damaged.
As shown in Figure 2, it has illustrated the installation site of moistureproof heater of the utility model business air conditioner.Air-conditioning system is general to be adopted centrifugal cooling fan, go up the air-out cooling fan or not to adopt cooling fan.When adopting centrifugal cooling fan, directly heater 2 is installed on the air inlet place of blower fan 1, make the air of hot blast in can the uniform heating switch board, strengthen the effect of dehumidifying; Air-out cooling fan or when not adopting cooling fan in the air-conditioning system practicality, can directly heater 2 be installed in protected device 3 near.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
