Description
Technical field
The utility model relates to Heating,Ventilating and Air Conditioning (HVAC) technical field, is a kind of protective system of Heating,Ventilating and Air Conditioning (HVAC) circulating water pump.
Background technique
Air-conditioner water system type is a half small-sized centralized fan coil system, is all born by water chiller-heater unit by indoor load.Each room fan coil unit is connected with water chiller-heater unit by pipeline, leans on provided hot and cold water to supply cold-peace heat supply.Water system flexible arrangement, independent regulation is good, and comfort level is very high, can meet the needs of complicated house type dispersion use, each room independent operating.In addition, water system air-conditioner novel at present is also one of best solution of floor heating system application, by the effective combination with floor heating, the mode of low water temperature large size low-temp radiation heating in employing, more more comfortable than traditional fan-coil heating system energy-conservation.
Current domestic heat supply, air-conditioner water system are in order to solve the expansion issues of water, and major part establishes elevated tank to carry out moisturizing.Also have peer machine Constant pressure tank to hold or the swell increment of water in bucking-out system.Above-mentioned two kinds of methods run into some engineering and are difficult to application, and such as certain heating housing estate, first stage of the project 8 myriametre 2 is built, and the second stage of the project 6 myriametre 2 is built.Engineering is designed and constructed by stages and in groups, build all roofings and be sloped roof, high level all can not arrange swelling water tank, according to market sale situation, developer determines that how high next building building lid is again simultaneously, therefore be difficult in this heating system adopt swelling water tank to solve the expansion issues of water, and the tank body volume brought by Constant pressure tank method is large, by the height restriction of boiler room.Select the volume of Constant pressure tank to need 15 meter 3 by the building of 8 myriametre 2 area of heat-supply services, if diameter is 2 meters, be highly then 3.5 meters, need Constant pressure tank 2 ~ 3, floor space is large, and investment is large again, is inappropriate concerning realtor.
Model utility content
Order of the present utility model is to provide a kind of protective system of Heating,Ventilating and Air Conditioning (HVAC) circulating water pump; it heats in the heating ventilation air-conditioning system of building construction, cold pipeline pressure fixing system adopts variable frequency pump level pressure; when civil power dead electricity, constant pressure water compensation apparatus quits work; circulating water pump bears the power potential energy that the static pressure of water in energy supply pipeline and water inertia produce; circulating water pump pressure-bearing is greater than for preventing the pressure causing circulating water pump to bear; or current drive circulating water pump rotation to make circulating water pump become power generating equipment, are burnt by distribution facility and cause economic loss.Be communicated with water pipe in the increase between return main that supplies of circulating water pump group, this connection water pipe add safety check, is shunted by safety check, reduce the pressure-bearing of circulating water pump.
To achieve these goals, the utility model is by the following technical solutions:
A kind of protective system of Heating,Ventilating and Air Conditioning (HVAC) circulating water pump; it includes the recycle pump group (S-1) in HVAC water system; water softening device (S-3); the feed main (1) of circulating water pump group, return main (4); it is characterized in that; be provided with between the feed main (1) and return main (4) of circulating water pump group and be communicated with water pipe (2), this connection water pipe (2) is in series with safety check (3).
Wherein, between feed main (1) and water softening device (S-3), frequency conversion water-supply and pressure-stabling water pump (S-2) is provided with.
Under the accident conditions of the utility model employing HVAC space, the protective system of circulating water pump, makes circulation under accident conditions, effectively can protect circulating water pump, prevent circulating water pump superpressure phenomenon from occurring, reduce economic loss.
The beneficial effects of the utility model are:
1, the utility model adopts Heating,Ventilating and Air Conditioning (HVAC) circulating water pump to add loaded check valve, effectively can protect the safety of circulating water pump under accident conditions.
2, under accident conditions, circulating water pump does not incur loss and can continue energy supply behind city power recovery.
3, protection circulating water pump can be effectively less because changing the economic loss that circulating water pump brings.
4, adopt frequency conversion water-supply and pressure-stabling water pump can improve the Economy of project, and decrease the investment of constant pressure arrangement.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the protection connected system of the utility model Heating,Ventilating and Air Conditioning (HVAC) water system, the capital equipment that it comprises has circulating water pump group S-1, frequency conversion water-supply and pressure-stabling water pump S-2, water softening device S-3.Be provided with between the feed main 1 and return main 4 of circulating water pump group and be communicated with water pipe 2, this connection water pipe 2 is in series with safety check 3.
Wherein, between feed main 1 and water softening device S-3, be provided with frequency conversion water-supply and pressure-stabling water pump S-2; Quit work at the situation down coversion water-supply and pressure-stabling water pump S-2 of civil power dead electricity, circulating water pump group S-1 bears the power potential energy that the static pressure of water in energy supply pipeline and water inertia produce, the pressure causing circulating water pump group to bear is greater than circulating water pump group pressure-bearing, or current drive circulating water pump group to rotate, make circulating water pump group become power generating equipment and distribution facility is burnt cause economic loss.Add loaded check valve 3 protective gear for this phenomenon, can prevent above-mentioned phenomenon from occurring, reduce economic loss.
In view of there being a lot of producer at present, feedwater constant pressure arrangement is not diverted in heating system with adding any transformation, and in the engineering had, really cause steady of system press unstable, system cannot normally be run, the constant pressure supply water of heating system of the present utility model compares with traditional pressurization methods, has the following advantages:
(1), compared with pressurized by elevated expansion tank, this system, not by the impact of building object height degree, directly can control level pressure at thermal source;
(2), compared with Constant pressure tank pressurization methods, pressure stability, floor space is little, low price;
(3), compared with common small pump, pressure set points is easy to control, economize on electricity;
(4), the real constant pressure point of certainty annuity is easy to than other pressure fixing system.
(5), when static pressure line is higher, can also suitably reduction system for backwater operation pressure, reduce the pressure-bearing of heating user interior radiator, adaptability is more extensive.
(6), owing to adopting this pressurization by make-up water pump mode, system is closed system, and air is difficult to the system of entering, and more meets the use of modern steel radiator system.
