Abstract
A four pipe FCU is provided, which is characterized in that: only one coil is mounted in a machine body; a cold-hot exchanging three way valve is connected and positioned between the coil and an external air conditioner water pipe. The invention skillfully utilizes the cold-hot exchanging three way valve to facilitate one coil being used in two ways, namely being served both as a cooling coil and the heating coil, thereby largely simplifying the structure, lowering the cost, shortening the volume, minishing the resistance and improving the cooling and heating efficiency.
Description
Technical field:
The present invention relates to a kind of air-conditioner tail end equipment capable, be specifically related to a kind of coil pipe of 4-pipe blower.
Background technology:
Traditional air conditioning terminal by blower fan and two mutually independently coil pipe form, two coil pipes link to each other with the warm water water pipe with the cold water water pipe of air-conditioner host output respectively, realize freezing or heat-production functions according to user's requirement.Two coil pipes are loaded in the body, and volume and weight is big, cost is high, and have increased the resistance of wind, have reduced cooling and warming efficient.
Summary of the invention:
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of simple in structure, volume is little, cost is low, reduce windage, improve the coil pipe of 4-pipe blower of cooling and warming efficient.
The technical solution used in the present invention is: this coil pipe of 4-pipe blower is only installed a coil pipe in body, is connected and installed with cold and hot crossover tee valve between coil pipe and the external air-conditioning water pipe.
The present invention is owing to be equipped with cold and hot crossover tee valve dexterously between coil pipe and external air-conditioning water pipe, so only need being installed, a coil pipe just can realize two kinds of functions of cooling and warming, the function that has replaced two independent coil pipes in the conventional fan coil pipe fully, dual-use, greatly simplify the structure, reduced cost, dwindled volume, reduce the resistance of wind, improved the efficient of fan coil.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Among Fig. 1: 1-coil pipe 2-chilled water goes out the 3-chilled water and goes into 4-warm water and go into 3-warm water and go out F1-entry electric T-shaped valve F2-water outlet electric T-shaped valve
The specific embodiment:
Referring to Fig. 1, this coil pipe of 4-pipe blower is only installed a coil pipe 1 in body, be connected and installed with cold and hot crossover tee valve F1, F2 between coil pipe 1 and the external air-conditioning water pipe, external air-conditioning water pipe is respectively that chilled water goes out 2, chilled water goes into 3, warm water goes into 4, warm water goes out 5.Cold and hot crossover tee valve can be one or two.When customer requirements freezed, motor-driven valve F1 action: B → C connected, and motor-driven valve F2 action: C → B connects, and chilled water is gone into 3 and gone out 2 to chilled water, and chilled water flows in coil pipe; When customer requirements heated, motor-driven valve F1 action: A → C connected, and motor-driven valve F2 action: C → A connects, and warm water is gone into 4 and gone out 5 to warm water, and warm water flows in coil pipe, thereby realizes the cold and hot conversion of fan coil.Also F1 or F2 can only be installed.
Claims (1)
1. a coil pipe of 4-pipe blower is characterized in that only installing a coil pipe in body, is connected and installed with cold and hot crossover tee valve between coil pipe and the external air-conditioning water pipe.
