The specific embodiment
The utility model discloses a kind of air-conditioner water system, with so that the water system Auto-drainage of air-conditioning unit, avoid water system to damage.The invention also discloses a kind of air-conditioning unit with above-mentioned air-conditioner water system.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the first structural representation of the air-conditioner water system that Fig. 1 provides for the utility model embodiment; The second structural representation of the air-conditioner water system that Fig. 2 provides for the utility model embodiment.
The utility model embodiment provides a kind of air-conditioner water system, comprises water-system pipeline A and is communicated in drainage pipeline on the water-system pipeline A, is communicated with the automatic drain valve B by ambient temperature control on the drainage pipeline.
The air-conditioner water system that the utility model embodiment provides, be communicated with automatic drain valve B at the drainage pipeline that is communicated with water-system pipeline A, automatic drain valve B closes when temperature is higher and the automatic unlatching when temperature is low, so that air-conditioner water system can be according to the environment temperature Auto-drainage under powering-off state, effectively avoided when temperature is low, having water in the water system and the damage that causes.
In the air-conditioner water system energising normal course of operation that the utility model embodiment provides, there is near the excessive or lower situation of temperature of automatic drain valve B of water-system pipeline A inside water pressure, very easily cause in this case automatic drain valve B fault open, thereby so that the water in the air-conditioner water system misprint.Occur for fear of this situation, also comprise the outage normally open solenoid valve C that is communicated on the drainage pipeline.Need to prove, the electric power system of outage normally open solenoid valve C is same with the electric power system of air-conditioner water system, and the control line of the normally open solenoid valve C that namely cuts off the power supply is installed to the power interface place of air-conditioning unit at the air-conditioner water system place that the utility model embodiment provides or it is controlled on the mainboard.Outage normally open solenoid valve C opens behind the coil blackout at the coil closed in electrified state.Under the air-conditioning unit is powered normal situation, outage normally open solenoid valve C remains closed condition, because outage normally open solenoid valve C is communicated on the drainage pipeline, so that drainage pipeline remains obstructed state, the situation of effectively having avoided the water in the air-conditioner water system to misprint.
As shown in Figure 1, outage normally open solenoid valve C is communicated on the pipeline section between water-system pipeline A and the automatic drain valve B.Above-mentioned pipeline section belongs to the part of drainage pipeline.Under air-conditioner water system is powered normal situation, outage normally open solenoid valve C is in closed condition, because outage normally open solenoid valve C is arranged between water-system pipeline A and the automatic drain valve B, can't go out by the water inlet that outage normally open solenoid valve C flows to automatic drain valve B so that flow into the water of drainage pipeline, open or all the water in the water-system pipeline A can not be discharged during closed condition so that automatic drain valve B is in.
As shown in Figure 2, automatic drain valve B is communicated on the pipeline section between water-system pipeline A and the outage normally open solenoid valve C.Above-mentioned pipeline section belongs to the part of drainage pipeline.Under air-conditioner water system was powered normal situation, outage normally open solenoid valve C was in closed condition.When being in closed condition, automatic drain valve B the water in the water-system pipeline A can not be discharged; When automatic drain valve B was in opening, the water in the water-system pipeline A flowed to outage normally open solenoid valve C by automatic drain valve B, because outage normally open solenoid valve C is in closed condition, the water in the water-system pipeline A can not be discharged equally.
In order to ensure the water that can be emptied completely in the air-conditioner water system, automatic drain valve B is lower than the lowest part of water-system pipeline A.Above-mentioned lowest part refers to air-conditioner water system part on close ground in running.
Please refer to Fig. 3, Fig. 4 and Fig. 5, the unlatching schematic diagram of the automatic drain valve B that Fig. 3 provides for the utility model embodiment; The automatic drain valve B that Fig. 4 provides for the utility model embodiment closes schematic diagram; The exploded perspective view of the automatic drain valve B that Fig. 5 provides for the utility model embodiment.
