Description
Technical field
The utility model belongs to heat supply water field, relates to a kind of air source hot pump water heater.
Background technology
The water heater product of generally selling on China water heater market is electric heater, gas heater, solar water heater and Teat pump boiler at present.Teat pump boiler since energy-saving and environmental protection, advantage such as safe and reliable be used widely, common Teat pump boiler is to form refrigerant circulation loop by compressor, condenser, evaporimeter, restricting element, and the condensation heat of utilizing condenser to produce heats domestic water.
But most air source hot pump water heaters of domestic production at present and sale are to design and process by winter condition, structures such as compressor, condenser, evaporimeter are all mated design with peak load, and under transition season and summer condition, unit load is very little, form a kind of " low load with strong power " phenomenon, cause the overall efficiency of energy waste, water heater low.
In addition, the adjusting of immediately heating water heater water temperature is to realize by regulating inflow, and is too high as temperature, strengthens inflow, otherwise, reduce inflow.But, for heat exchanger, turn down in a small amount and can have influence on its heat exchange effect, thereby can cause the heat exchange effect to worsen to a certain degree the time unit can not normally be used when the water yield is little, so its adjustable range is less, the reduction of the adaptability of water heater.
Summary of the invention
Order of the present utility model has and is to provide the air source hot pump water heater that a kind of efficient is higher, adaptability is higher.
The utility model is achieved through the following technical solutions:
A kind of air source hot pump water heater, form refrigerant circulation loop by compressor, condenser, evaporimeter, restricting element, the water side of condenser is provided with water inlet, delivery port, and described compressor, condenser, evaporimeter, restricting element are at least two and form at least two refrigerant circulation loops respectively; In these at least two described condensers, be connected with water inlet pipe on one of them described water inlet, be connected with outlet pipe on another described delivery port, and remaining described water inlet, delivery port connect from beginning to end by tube connector and form the water route cascaded structure.
In the utility model, have two refrigerant circulation loops at least, when hot water heating temperature rise is low, can only start a compressor to improve the efficient of water heater; When hot water heating temperature rise is higher, can start two compressors simultaneously satisfying the requirement that hot water heats, and condenser water route cascaded structure, cold water heats through the two poles of the earth, then the water temperature liter through each compressor assembly reduces, and operating mode is more stable, more helps the operation of compressor.This structure also has an advantage: Load Regulation can be opened the platform number and two kinds of compound modes of water regulating valve are regulated by compressor, so adjustable range is wider, adaptability is stronger.
The novel further improvement of this reality is:
In each described evaporimeter, have at least the heat exchanger tube of two described evaporimeters to pass same fin.The heat exchanger tube of a plurality of described evaporimeters passes same fin, can improve heat exchange efficiency, when having only a compressor operating in two compressors, the heat exchange efficiency of evaporimeter is doubled.
Side at described evaporimeter is provided with blower fan, and this blower fan has two gears at least, and this blower fan is electrically connected with described control circuit.When a compressor operating, to evaporator blower, when two compressor operating, blower fan will be at high tap position to evaporator blower at low-grade location for blower fan; With the energy-conservation and heat exchange effect that realizes.
The ability difference of at least two described compressors.When the water heater whole matching, can select the compressor of different abilities according to required hot water amount, with energy savings as much as possible; Compressor start as little ability can satisfy the heat requirement, then start this compressor, can not satisfy institute's calorific requirement requirement as little ability compressor start, then start the compressor of big ability, still can not satisfy the heat requirement as this compressor start, then start two compressors, with the ability that realizes institute's startup compressor as much as possible and the capabilities match of required hot water, to improve energy-saving effect.
Described outlet pipe is connected with boiler and communicates, and is provided with the hot water outlet pipe on this boiler.Be provided with after the boiler, the water temperature of hot water is more stable, and boiler also has the water storage effect simultaneously.
On described boiler, be provided with hot water return pipe.In large-scale hot water occasion, after the hot water output, if the part room does not use water heater, time long back water dispels the heat because of pipeline, and water temperature can descend, and hot water flows back in the boiler by hot water return pipe again, can guarantee with water spot hot water water temperature with avoid waste.
Be provided with backwater heating tube connector between described boiler and one of them the described water inlet, on this backwater heating tube connector, be provided with water pump.Water pump can be failed back condenser once more with the water in the boiler and heat, and heating for multiple times can improve water temperature, especially is being provided with on the situation of hot water return pipe, may be on the low side from the water temperature that hot water return pipe flows back to, water temperature can be improved once more by the circulation heating.
Described outlet pipe is provided with temperature inductor, described water inlet pipe is provided with water control valve, and this temperature inductor, water control valve are electrically connected with described control circuit.Temperature inductor carries out sensing to the water temperature of outlet pipe, crosses when low when water temperature, and by control circuit control water control valve, can reduce the water yield of flowing through water temperature is raise, otherwise, then increase the current of flowing through.
To sum up, the utility model has the advantages that:
1, at least two refrigerant circulation loops can select to start a compressor or a plurality of compressor as required, and the heating capacity of water heater and actual needs are adapted, and improve the operating efficiency of water heater, reduce energy dissipation;
2, double compressor system, Load Regulation can be opened the platform number and two kinds of compound modes of water regulating valve are regulated by compressor, so adjustable range is wider, adaptability is stronger.
3, condenser water route cascaded structure when load is big, starts two compressors, and cold water heats through the two poles of the earth, and then the water temperature liter through each compressor assembly reduces, and operating mode is more stable, more helps the operation of compressor:
When 4, starting, but a plurality of compressor asynchronous starting starts load to reduce;
5, the shared fin of a plurality of evaporimeters can improve heat exchange efficiency;
6, blower fan gear and compressor operating state adapt, and it is energy-conservation to improve, the heat exchange effect.When only opening a compressor assembly, be automatically brought to slow-speed of revolution operation, reduce blower fan power consumption and noise.
