Abstract
The invention relates to a combined anti-freezing device of an air-conditioning water system in a cold region. The combined anti-freezing device comprises a water system pipeline of an air-conditioning device, a mechanical temperature control valve and a normally closed magnetic valve. The mechanical temperature control valve is installed at the lowest position of the water system pipeline of the air-conditioning device, the normally closed magnetic valve is serially connected to the mechanical temperature control valve, and the mechanical temperature control valve is connected with a power supply source of the air-conditioning device. when the environment temperature is lower than zero and the magnetic valve is turned off, the device can be automatically opened to thoroughly drain water in a water system through the mechanical temperature control valve and the normally closed magnetic valve arranged at the lowest position of the water system pipeline of the air-conditioning device, and the phenomenon that the water system pipeline of the air-conditioning device is frozen and accordingly the air-conditioning device cannot operate or is damaged can be effectively prevented.
Description
Technical field
The present invention relates to a kind of air-conditioner water system defroster, present invention relates especially to a kind of cold district air-conditioning water system
System combination defroster.
Background technology
Temperature outside northern China winter room is relatively low, and Jing often occurs central air conditioning equipment water system and is frozen the bad thing of rhegma
Therefore, cause central air conditioner system to be forced work out of service, severely impact normal production and the work of air conditioner user.
To avoid air-conditioning equipment water system from being frozen, rhegma is bad, and the measure of filling anti-icing fluid in water system can reach antifreeze
Effect, however it is necessary that the water system tubing of resistance to antifreeze corrosion is selected, if charging amount is larger, it will make whole air conditioning system
Initial cost is greatly increased.
At present, it is most of it is air conditioning unit carry automatic freezing-protective function, start automatic freezing-protective in the close zero degree of ambient temperature,
Water temperature in water system is raised, being prevented effectively from air-conditioner water system equipment, to be frozen rhegma bad.But during air-conditioning equipment power-off, machine
The antifreeze function that group is carried will fail, and not reach antifreeze purpose.Accordingly, it would be desirable to one kind in the winter time air-conditioning sets under powering-off state
Standby water system self-draining arrangement.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided one kind can be effectively prevented because air-conditioning sets
The cold district of the generation that the air-conditioning equipment that standby water system pipeline freezes and causes cannot run and damage air-conditioning equipment phenomenon is empty
Water transfer system combines defroster.
According to the technical scheme that the present invention is provided, the cold district air-conditioner water system combines defroster, and it includes sky
The water system pipeline of tune equipment, mechanical temperature control valve and normally closed solenoid valve；In the lowest point peace of the water system pipeline of air-conditioning equipment
Equipped with mechanical temperature control valve, the power supply of normally closed solenoid valve, normally closed solenoid valve and air-conditioning equipment is in series with mechanical temperature control valve
Power supply is connected.
Mechanical temperature control valve and normally closed solenoid valve by being arranged on the water system pipeline lowest point of air-conditioning equipment of the invention,
In the case that ambient temperature is less than zero degree and electromagnetic valve power-off, can automatically open up, water excretion in water system is clean, can be with
Effectively prevent the air-conditioning equipment caused because air-conditioning equipment water system pipeline freezes from cannot run and damaging air-conditioning equipment phenomenon
Occur.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
With reference to specific embodiment, the invention will be further described.
The cold district air-conditioner water system combination defroster, it includes the water system pipeline 101, mechanical type of air-conditioning equipment
Temperature-sensing valve 102 and normally closed solenoid valve 103；Mechanical temperature control valve is installed in the lowest point of the water system pipeline 101 of air-conditioning equipment
102, the power supply of normally closed solenoid valve 103, normally closed solenoid valve 103 and air-conditioning equipment is in series with mechanical temperature control valve 102
It is connected.
When ambient temperature is less than zero degree, the valve of mechanical temperature control valve 102 is automatically opened up, the water in water system pipeline 101
The top of normally closed solenoid valve 103 is flow to, it is air conditioning unit to carry automatic freezing-protective disabler, air-conditioning equipment when air-conditioning equipment power-off
Water system pipeline has risk of icing, and the valve of normally closed solenoid valve 103 is automatically opened up, and water passes through mechanical temperature control valve 102 in water system
With normally closed solenoid valve 103 by water emptying, it is to avoid it is bad that air-conditioner water system equipment is frozen rhegma.
In the case of ambient temperature is powered higher than zero degree or air-conditioning equipment, air-conditioning equipment is without draining, mechanical temperature control valve
102 or normally closed solenoid valve 103 at least one valve be in closure state, drainage system is closed.
