Abstract
The utility model discloses a double cool source fan coil. The double cool source fan coil comprises a fan, a coil and a box. The fan and the coil are arranged in the box. The box is provided with a return air inlet and an air supply outlet. The double cool source fan coil is characterized in that the coil comprises two independent groups of a first coil and a second coil. The first coil transfers heat with an air-condition freeze water which is supplied by a water chilling unit concentratedly. The second coil transfers heat with a refrigerating fluid which is in common used by a frequency conversion multi-union chamber outer machine. The double cool source fan coil enables a terminal fan coil system to correspond two methods of cool source refrigeration to realize one machine dual use and save initial cost and precious underground installation space. The double cool source fan coil is easy to control and regulate, and high in application value.
Description
Technical field
The utility model relates to refrigeration system equipment, concrete refers to a kind of pair of low-temperature receiver fan coil.
Background technology
In some subway stations, normally run daytime in the period at present, public area and equipment control are all adopted handpiece Water Chilling Units with room district cold source of air conditioning; In the improper operation period at night, the public area of refrigeration duty maximum need not refrigeration, and the equipment component management is with still opening air-conditioning in the room, this moment, the refrigeration duty in this part room was also little, adopted the multi-joint split-type air conditioner of variable refrigerant volume, the station handpiece Water Chilling Units is closed, and reaches the purpose of energy savings, so not only can make two cover systems mutually for subsequent use, also can make handpiece Water Chilling Units for a long time in the operation of efficient district simultaneously.But problem is these rooms that need air conditioning in 24 hours and has adopted two cover end equipments, takies so on the one hand this nervous underground space, has increased on the other hand cost of investment.
Summary of the invention
The purpose of this utility model is to use the drawbacks of two cover end-equipments in order to overcome conventional system, proposes a kind of simple in structurely, and cost is low, and it is convenient to implement, and handpiece Water Chilling Units and connected off-premises station two low-temperature receiver fan coils that can share.
For achieving the above object, two low-temperature receiver fan coils that the utility model is designed, comprise blower fan, coil pipe and casing, described blower fan, coil pipe are arranged on box house, described casing is provided with return air inlet and air outlet, its special character is: described coil pipe comprises two groups of independently the first coil pipe and second coil pipes, and the air conditioning water heat exchange that provides is provided for described the first coil pipe and handpiece Water Chilling Units, the cold-producing medium heat exchange that described the second coil pipe and connected off-premises station are commonly used.
As preferred version, the input of described the first coil pipe is communicated with into loop with outlet pipe with handpiece Water Chilling Units by water inlet pipe respectively with output; The input of described the second coil pipe is communicated with into loop with muffler with the connected off-premises station by feed pipe respectively with output.
Further, be provided with the first electrically operated valve of control water inlet pipe break-make on the described water inlet pipe.
Further, be provided with the second electrically operated valve of control feed pipe break-make on the described feed pipe.
The utility model has the advantage of: it can make the corresponding two kinds of low-temperature receiver refrigeration modes of a cover tail-end blower fan coil system, realizes dual-use.Save initial cost and valuable underground installing space, and control and regulation are simple.This coil pipe can according to the corresponding heat exchanger start and stop of the on off control of air-conditioner host, realize that two kinds of different air-conditioning forms share the feasibility of a cover end-equipment.Only need to install two groups of heat exchangers, just can realize dual-use, save the underground space and equipment cost, realize the integrated of subway station part air-conditioning equipment, the end-equipment of two kinds of multi-form air-conditioning systems is combined into one, has saved installing space.
The utility model is applied to the room that the subway station needs air conditioning in 24 hours, can promote in the subway station, uses for reference and use, and has great Social benefit and economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, water inlet pipe, 2, outlet pipe, 3, feed pipe, 4, muffler, the 5, first coil pipe, 6, the second coil pipe, 7, air outlet, 8, return air inlet, 9, blower fan, 10, handpiece Water Chilling Units, 11, connected off-premises station, 12, casing, F1, the first electrically operated valve, F2, the second electrically operated valve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Two low-temperature receiver fan coils as shown in the figure, comprise blower fan 9, coil pipe and casing 12, blower fan 9, coil pipe are arranged on casing 12 inside, casing is provided with return air inlet 8 and air outlet 7, coil pipe comprises two groups of independently the first coil pipe 5 and second coil pipes 6, the first coil pipe 5 is concentrated the air conditioning water heat exchange that provides with handpiece Water Chilling Units 10, the cold-producing medium heat exchange that the second coil pipe 6 and connected off-premises station 11 are commonly used; The input of the first coil pipe 5 is communicated with into loop with outlet pipe 2 with handpiece Water Chilling Units 10 by water inlet pipe 1 respectively with output; The input of the second coil pipe 6 is communicated with into loop with muffler 4 with connected off-premises station 11 by feed pipe 3 respectively with output; Be provided with the first electrically operated valve F1 of control water inlet pipe 1 break-make on the water inlet pipe 1; Be provided with the second electrically operated valve F2 of control feed pipe 3 break-makes on the feed pipe 3.
The first coil pipe 5 and the second coil pipe 6 are the heat exchanger of two groups of different area, and when daytime, station handpiece Water Chilling Units 10 was opened, electrically operated valve F1 connected, and air conditioning water enters the first coil pipe 5 by water inlet pipe 1, and get back to handpiece Water Chilling Units 10 by outlet pipe 2 after the room air heat exchange.When night, station handpiece Water Chilling Units 10 was out of service, part still needs the room of air conditioning, open connected off-premises station 11, the second electrically operated valve F2 and connect thereupon, the cold-producing medium refrigerant is got back to connected off-premises station 11 by muffler 4 after entering the first coil pipe 6 and room air heat exchange by feed pipe 3.
Operation principle of the present utility model is as follows: fan coil is installed two groups of coil pipes, two groups of coil pipes respectively from different cold-producing medium heat exchange: one group with the cold-producing medium heat exchange commonly used of connected machine, one group with the concentrated air conditioning water heat exchange that provides of handpiece Water Chilling Units.Simultaneously, two groups of coil pipes are under different refrigerant effects, and the heat exchange amount is identical, determine length and the heat exchange form of two groups of coil pipes under this principle.Every group of coil pipe is connected entrance with air-conditioner host electrically-controlled valve is set, when corresponding main frame is started shooting, and this valve opening, otherwise be in closed condition.
