Abstract
The utility model discloses a fan coil, which comprises a water supply connecting pipe, a water return connecting pipe and a condensed water pipe. The water supply connecting pipe and the water return connecting pipe are respectively and additionally provided with a bypass pipe made of galvanized steel pipe materials, a low-flow circulation pump is connected in parallel with a past daily operation pump, and the low-flow circulation pump is flexibly connected with a pipeline adjacent to the circulation pump through rubber. The bypass pipes are welded directly on the water supply connecting pipe and the water return connecting pipe. Certain flow of water in the fan coil system is maintained by the aid of the low-flow circulation pump in operation, so that frost crack of the pipelines due to icing in winter can be avoided. The pipe connecting way of the fan coil is simple and convenient to operate, and the purpose of equipment maintenance can be achieved by slighting modifying the water supply connecting pipe and the water return connecting pipe with the traditional pipe connecting way of the fan coil.
Description
Technical field
The utility model relates to the air conditioner ventilation apparatus field, particularly a kind of fan coil.
Background technology
In field of heating ventilation air conditioning, fan coil belongs to a kind of common air conditioner end equipment, the desirable end prod of central air-conditioning particularly, be widely used in hotel, office building, hospital etc., fan coil room air and outdoor mixing air are cooled off by surface cooler or heat after send into indoorly, indoor air temperature reduced or raise, to satisfy people's comfortableness requirement, because its technology maturation, superior performance, flexible for installation have obtained using widely.
But, because fan coil generally adopts the carrier of water as its cooling and warming, following risk takes place in the winter time easily: when not using for a long time when being filled with water in the middle of system, the equipment, if insulation fails to reach its due effect because of various reasons, the water in the equipment pipe will freeze at low temperatures.When this phenomenon occurs in the fan coil, because the back volumetric expansion of freezing, coil pipe will be caused the badly damaged of equipment by bursting by freezing.
Also have unit when not using fan coil for a long time, intrasystem water not to be discharged, but when power system capacity was excessive, this behavior meeting caused the waste of water, can not guarantee that intrasystem water all is discharged totally, exists the risk of frost crack pipe all the time.
Summary of the invention
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of fan coil, makes inner water can keep circulating, the risk of frost crack pipe when avoiding not using for a long time in the winter time.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of fan coil, comprising supplies water takes over, backwater is taken over, condensate pipe, be characterized in, on described water supply adapter and backwater are taken over, respectively increased by bypass pipe that one road coating steel pipe material makes and itself and connect, and the circulating pump that a low discharge is set and former day-to-day operation pump are mutually and connect.
The circulating pump of described low discharge connects adjacent pipeline in succession by rubber is soft, connects above-mentioned water supply water pipe by pipeline then.
Further, described two-way bypass pipe directly is welded on the pipeline of above-mentioned water supply adapter and backwater adapter.
On supplying water adapter, that section that described bypass pipe connects gate valve is set, the current that control is supplied water and taken over;
In that section backwater adapter that described bypass pipe connects electric two-way valve and ball valve are set, the control backwater is taken over the current in the pipeline.
Above-mentioned water supply adapter, backwater are taken over, two bypass pipes are formed the loop that current lead to circulating pump.
By the running of circulating pump, make the intrasystem current of above-mentioned pipeline can keep certain flowing, and avoid when winter, freezing frost crack pipe.
The beneficial effects of the utility model are, the adapting method principle is simple, and is easy to operate, under the situation of continuing to use conventional fan coil pipe pipe-connecting mode its water supply taken over and the small transformation of backwater adapter carrying out, can reach the purpose of service equipment, avoid the risk of fan coil in the ice up in winter bursting by freezing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Be easy to understand understanding in order to make technological means of the present utility model, creation characteristic and to reach purpose, further set forth the utility model below in conjunction with specific embodiment.
Embodiment:
Referring to Fig. 1, a kind of fan coil, comprising supply water to take over 1, backwater takes over 2, condensate pipe 3, two bypass pipes 11 and 12 and circulating pump 4.
Increase the circulating pump (not marking among the figure) of a low discharge in traditional fan coil system, the circulating pump of described low discharge and day-to-day operation water pump mutually and connect connect above-mentioned water supply water pipe 1 by pipeline then.
The circulating pump of above-mentioned low discharge also connects adjacent pipeline in succession by rubber is soft, and forms the negotiable connected loop of water with backwater adapter 2, condensate pipe 3 and two bypass pipes 11/12.
As shown in Figure 1, the pipeline of supply water to take over 1, backwater taking over 2, condensate pipe 3 adopts the DN20 models, two bypass pipes 11 and 12 adopt the pipeline of DN15 models.
Owing to there is not condensed water to produce, condensate pipe 3 does not have the risk of bursting by freezing during winter; And the adapter 1 of supplying water takes over 2 owing to need heat with backwater, has hot water to flow in pipeline usually.Run into when equipment does not move for a long time during the Spring Festival holiday; if the Nei Shui of system does not drain only; hot water in the pipeline gradually becomes cold water; the phenomenon of freezing takes place sometimes; bursting by freezing water supply adapter 1 takes over 2 with backwater; and by circulating pump that increases a low discharge and the bypass pipe that respectively increases by one road DN15 model in described water supply adapter 1 and backwater adapter 2; tubing is coating steel pipe; when stopping using in fan coil winter; the circulating pump of opening above-mentioned low discharge carries out energy-saving run; can under the condition of low energy consumption, evade icing risk, protection equipment.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
