Abstract
The invention relates to a central air conditioning system and provides a novel central air conditioning system which is accurate in control, flexible in use, comfortable in air supplying temperature, and capable of being connected to floor heating in winter. The central air conditioning system comprises an outdoor host, indoor hosts, fan coils and floor heating devices. The outdoor host is connected with the indoor hosts. The central air conditioning system is characterized in that the outdoor host is connected with at least one indoor host, and one indoor host is connected with at least one fan coil and at least one floor heating device. Therefore, the central air conditioning system not only has air supplying comfort of a traditional central air conditioning, but also has flexibility of a variable refrigerant flow rate direct evaporative type and multi-split type air conditioning unit.
Description
Technical field
The present invention relates to a kind of central air conditioner system.
Background technology
At present, have two large class central air conditioner systems on the market, a class is the central air conditioner system that tradition adopts refrigerating medium, such as main frame traction fan coil or large-scale air processing units such as screw machine, centrifuge, lithium bromide absorption-type machine unit; One class is exactly the direct-evaporation-type VRF Air Conditioning System of the variable refrigerant volume that just risen in recent years.Tradition adopts the central air conditioner system of refrigerating medium, traction fan coil indoor set quantity is all many, bad for the local offices flexibility, as: an office block adopts the conventional central air-conditioning system, Saturday or Sunday, several offices needed overtime work, and air-conditioning can't use, and also needed the main frame that power is huge to open even main cause is only opened several fan coil indoor sets, power consumption is huge, so Saturday and weekend can't provide for indivedual offices the needs of air conditioning; The direct-evaporation-type VRF Air Conditioning System of variable refrigerant volume use flexibly, but wind pushing temperature was low when freezed summer, allowed the people feel very uncomfortable.
Summary of the invention
Central air conditioner system of the present invention overcomes the defective of above-mentioned two large class central air conditioner systems, the central air conditioning system that provide a kind of and control accurately, use flexibly, wind pushing temperature is comfortable, can accesses floor heating winter.
The technical scheme of central air conditioner system of the present invention is such: it comprises outdoor host computer, indoor host computer, fan coil and floor heating device, outdoor host computer is connected with indoor host computer, outdoor host computer be connected indoor host computer and connect, an indoor host computer is connected with floor heating device with at least one Fans coil pipe.
Indoor host computer arranges 1 ~ 16.
Fan coil and floor heating device are in parallel, are connected with indoor host computer by triple valve after the parallel connection.
It also comprises CPU, and outdoor host computer, indoor host computer, fan coil, floor heating device all are connected with CPU, carries out centralized Control by CPU.
The scheme of central air conditioner system of the present invention is such: it comprises outdoor host computer, indoor host computer, fan coil and ground heating system, outdoor host computer is connected with indoor host computer, indoor host computer is connected ground heating system and is connected with fan coil, outdoor host computer can 1 ~ 16 indoor host computer of traction, indoor host computer is connected refrigeration use in summer with many Fans coil pipe, indoor host computer is connected winter heating to be used with the ground heating system of certain area.Describe as an example of three indoor host computers of outdoor host computer traction example: three indoor host computers of outdoor host computer traction, three indoor host computers are according to freezing or heating needs, the traction building is divided into Three regions, realizes that this trizonal air-conditioning and ground heating system carry out individual operation and stop.Summer, outdoor host computer and indoor host computer were produced 7 ℃ of cold water, circulated in fan coil by cold water by water pump, and fan coil is delivered to cold indoor, taked the indoor supply air temperature difference of this mode little, and human body sensory is comfortable; Winter, outdoor host computer and indoor host computer were produced 50 ℃ of hot water, circulated in floor heating by hot water by water pump, and floor heating is delivered to heat indoor, taked this mode to heat, and the indoor temperature gradient more meets human body comfort; The air-supply comfortableness that this central air conditioner system namely has a conventional central air-conditioning has again the VRF Air Conditioning System flexibility of the direct-evaporation-type of variable refrigerant volume.
Description of drawings
Fig. 1 is the schematic diagram of the embodiment 1 of central air conditioner system of the present invention.
1-outdoor host computer, 2-indoor host computer, 3-fan coil, 4-floor heating device, 5-three-way magnetic valve.
The specific embodiment
Embodiment 1:
