Abstract

The utility model relates to a central air conditioner or a commercial air conditioning system. A novel variable-frequency multi-connection type water heat exchanger unit disclosed by the utility model provides a mode that one outdoor machine is connected with a plurality of water heat exchangers in different indoor areas; and moreover, each water heat exchanger is also connected with a secondary water pipeline, so that the water heat exchangers are used in end refrigerating or heating equipment and domestic water heaters in different rooms in an indoor space. The novel variable-frequency multi-connection type water heat exchanger unit comprises an outdoor machine of an air conditioner and water heat exchangers, wherein at least two water heat exchangers are arranged, the water heat exchangers are connected with the outdoor machine of the air conditioner after the water heat exchangers are connected in parallel, each water heat exchanger is connected with a secondary water pipeline, and the water heat exchangers and the secondary water pipeline are both arranged in an indoor space. In the actual application of the variable-frequency multi-connection type water heat exchanger unit, the collocation mode of the indoor equipment of the variable-frequency multi-connection type water heat exchanger unit is very convenient. One single water heat exchanger does not need a very large type, the water heat exchangers can be respectively started or stopped in actual use, and the utilization rate of energy resources is high; the subsequent connecting equipment has flexible and diversified forms and can be completely designed in a customization way according to the actual requirement of each room of a user; and the entire system has a compact structure, is convenient to install and is reliable in running.

Description

Novel connected formula water heat exchanger unit
Technical field
The utility model relates to a kind of central air-conditioning or business air conditioner system.
Background technology
Commercial air-cooled VRF Air Conditioning System develops to multifunctional direction, can connect the cold indoor set of many typhoons with the cold off-premises station of last typhoon, can connect a water heat exchanger and the cold indoor set of many typhoons now, wherein water heat exchanger is used for the heat exchange of refrigerant and water, and air-conditioning system is expanded to the air-conditioning unit of " air-cooled+domestic hot-water+floor heating " composite type by air-cooled unit completely like this.But in application in practice, more than the mode of this " off-premises station connects a water heat exchanger and Duo Tai indoor set " still have very big inconvenience, for example a plurality of rooms need the ground heating equipment and terminal water temperature does not meet the demands, the indoor set that warms up simultaneously in the room causes the equipment waste with installing, indoor set fan coil with high costs and cheap is not easy the adding system, and the indoor set running noise is bigger or the like.In sum, we use the practical problem of the air-cooled/comprehensive VRF Air Conditioning System of domestic hot-water/floor heating of novel manner solution of " off-premises station connects many water heat exchangers ".
Summary of the invention
Novel connected formula water heat exchanger unit of the present utility model provides the mode of many water heat exchangers of off-premises station connection different chamber's inner region, and every water heat exchanger is connected with the secondary water lines again, makes to obtain in end refrigeration in indoor not chummery or heating equipment and the domestic hot-water's device using.
The technical scheme of novel connected formula water heat exchanger unit of the present utility model is such: it comprises air-conditioner outdoor unit, water heat exchanger, water heat exchanger is set to two at least, be connected with air-conditioner outdoor unit after the water heat exchanger parallel connection, each water heat exchanger is connected with the secondary water lines, and water heat exchanger and secondary water lines all are arranged on indoor.
The secondary water lines comprise domestic hot-water's pipe, fan coil, hot water pipe, domestic hot-water's pipe, fan coil, hot water pipe back in parallel mutually be connected with water heat exchanger.
Heat transmission equipment is set to plate type heat exchanger, shell and tube exchanger or double pipe heat exchanger in the water heat exchanger.
Novel connected formula water heat exchanger unit of the present utility model also has following advantage simultaneously except having the advantage that improves household air-conditioner:
1) because water heat exchanger is separately positioned on different use zones, closer from the user, so even the equipment of water system distance is very long, its water temperature still can be guaranteed;
2) no longer need the air-cooled indoor set that warms up simultaneously in the single room with installing, but can select refrigeration plant and heating equipment flexibly according to user preferences;
3) can use cheap fan coil to substitute expensive air-cooled indoor set;
4) noise effect in the indoor watering equipment that all makes, no cryogen chamber;
5) promptly possess the multi-connected air conditioner simple installation, running is reliable, the characteristics that maintenance cost is low, and it is low to have both water-cooled unit complete machine cost simultaneously, and the stability of a system is good, the characteristics that users'comfort is higher.
