Description

The novel non-bearing type air energy heat pump water heater of family expenses
Technical field:
The utility model relates to a kind of water heater, the novel non-bearing type air energy heat pump water heater of especially a kind of family expenses.
Background technology:
Air energy heat pump water heater is at present more and more to receive the favor of vast family; Its good energy-conservation property is also just meeting the development tactics of national energy-conserving and environment-protective; Therefore; How to let air energy heat pump water heater when getting into huge numbers of families, bringing convenience and be worth for users really is the key point of air-source water heater.
And at present traditional domestic air ability Teat pump boiler; All be to adopt bearing type water tank; The pressure that just directly adopts running water is as flow dynamic, and this structure is simple relatively for the process structure of air energy heat pump water heater; But for the user in use, will run into a lot of unfavorable situation.
The typical operation of conventional domestic bearing type air ability Teat pump boiler:
1). running water is filled with water tank, and because of water tank is the seal and pressure bearing water tank, therefore, when the user opened tap, its pressure equaled running water water inlet pressure;
2). running water is filled with water tank, and heat pump main frame MCU is through temperature detection, when detecting water temperature and being lower than user's design temperature, just starts compressor;
3). compressor operation is compressed into liquid state with refrigerant from the gaseous state shape, and is depressed in the copper pipe that is immersed in the water tank;
4). when being compressed into liquid state because of gaseous coolant, discharge a large amount of heat, these heat energy are through being immersed in the water transmission of copper pipe in water tank in the water, thereby gradually water are heated;
5). through continuous circulation, water is heated to design temperature, and this moment, compressor shut down;
6). when the user opens tap, hot water flows out from the hot water mouth, and because of water tank is an airtight water tank, the lower running water of temperature this moment also begins to flow into water tank automatically, and just how much hot water flows out from water tank, and then cold water also flows into how much to water tank;
7). after the lower running water of temperature constantly injects, will mix mutually, the hot water temperature is reduced fast with the hot water of water tank the inside.At this moment, even the user stops water, the water in the water tank also has cooling by a relatively large margin because of having injected the lower running water of temperature;
8). when the hot water temperature is reduced to the temperature four degree left and right sides of setting; Main frame is the entry into service compressor again; Temperature has been descended but heat far above the water in the water tank of running water temperature, just compressor water to water tank under the water temperature condition with higher heats once more.
Through the course of work of analysis conventional family expenses bearing type air ability Teat pump boiler, be not difficult to analyze this system and have many shortcomings:
1). the water tank cost is high: the pressure bearing and seal water tank be because of will considering to reach 9 kilograms pressure, so its technology, material requirements height;
2). pressure of hot water is influenced greatly by running water: because of this system's hot water is to lean on tap water pressure to extrude; So in use, the pressure of running water will equal the discharge pressure of hot water, so in the water use peak phase; Easily no hot water output or hot water output pressure are too little, and result of use is had a greatly reduced quality;
3). mixed water phenomenon is serious: Yi Bian because of using hot water, Yi Bian inject the low temperature running water, therefore, the hot water that certainly leads to high temperature is obscured by the lower running water of temperature, causes hot water can't satisfy user demand; Particularly under the very low situation of running water temperature in winter, a spot of cold water injects will influence a large amount of hot water, the dischargeable capacity of water tank even less than 1/3rd of nominal volume;
4). Energy Efficiency Ratio is low, and the compressor life-span is short: water temperature is more than 37 degrees centigrade when being used for the heat pump work of pressure-bearing type, exactly the low efficiency district of heat pump; Because the mixed water image of pressure-bearing type, high as far as possible (more than 60 degrees centigrade) that the user have to establish water temperature, the Energy Efficiency Ratio that this has just further reduced heat pump has shortened life-span of compressor greatly.
Summary of the invention:
To the deficiency of above-mentioned prior art, the utility model provides a kind of family expenses novel non-bearing type air energy heat pump water heater.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: the novel non-bearing type air energy heat pump water heater of family expenses, non-press-bearing water tank is connected with main frame with outlet pipe through water inlet pipe.Be provided with compressor, condenser, fan, heat exchanger and water circulating pump in the main frame.Compressor one end connects condenser, and the other end connects heat exchanger, and fan is located at by the condenser.Condenser is connected with heat exchanger through copper pipe.Main frame is provided with running water inlet and hot water outlet.The running water inlet connects normally open solenoid valve, first check valve, normally closed solenoid valve and heat exchanger in the main frame successively.Hot water outlet connects water flow detector, second check valve and the water circulating pump in the main frame successively.The other end of water circulating pump is connected with the non-bearing type water tank through outlet pipe.Heat exchanger is connected with the non-bearing type water tank through water inlet pipe.The bottom of non-bearing type water tank is provided with pressure sensor and the temperature sensor that is connected with main frame, and the upper end is provided with leakage port.

2, there is not the water phenomenon of mixing: do not rely on tap water pressure because of the user uses the pressure of hot water; Therefore system can be in the process of user's heat water; The lower running water of implantation temperature not; So can realize 100% constant temperature water supply, reached maximum hot water use amount, reach 100% rate of thermal water utilization (pressure-bearing type winter rate of thermal water utilization in addition less than 1/3rd);
3, Energy Efficiency Ratio is high, really energy-conservation: be that running water from low temperature begins during heating; Having avoided the conventional domestic pressure-bearing type Teat pump boiler most of the time is the situation that is operated in the high temperature circulation heating; System is worked under the highest, the optimal state of Energy Efficiency Ratio; Realize the maximum use of the energy, Energy Efficiency Ratio generally speaking can be higher by 50% than traditional pressure-bearing type system;
4, the compressor life-span is long: because of compressor not as traditional pressure-bearing type system, the most of the time is operated under the situation of high temperature, high pressure, so the life-span of compressor also will prolong greatly, even can improve more than the twice;
5, hot water is not influenced by tap water pressure: avoided traditional pressure-bearing type heat hydraulic pressure of system to rely on the situation of tap water pressure, even therefore stay in the user of high building, needn't worry that the heat hydraulic pressure is little, the situation of result of use difference yet;
6, heating the water yield can arbitrarily control: owing to adopted stepless pressure sensor; Can realize needing how much hot water what just heat; Not only soon but also power saving, even avoided traditional pressure-bearing type system only to need some hot water, also must be heated to design temperature to whole box water; And unnecessary cool again after a while situation has reduced waste.
7, built-in function of increasing pressure: adopt the design of water circulating pump pressurization, solved the not enough or anhydrous difficult problem that goes out of water use peak phase hydraulic pressure, the function of water storage box of can holding concurrently.
8, water tank can arbitrary shape; To utilize the space to greatest extent: because water tank pressure-bearing not; Therefore arbitrary shape can be made, even the high usage (and traditional bearing type water tank inner bag must be cylindrical) of the water tank of any moulding can be customized according to client's parking space with the implementation space.
9, water tank can be parallel extended: because of water tank pressure-bearing not, so can a plurality of water tanks parallel connections use, can realize that also main frame and water tank can combination in any; In some occasions; Main frame can also be connected with regular solar is very convenient, replaces the electrothermal tube of solar energy, greatly energy savings.
