Abstract
The invention discloses an intermediate temperature directly-heated air source heat pump hot water machine set, comprising a refrigeration system composed of a compressor, a wind side heat interchanger, a blower, a flow regulating component and a water side heat interchanger; cycle water of a water system and medium of the refrigeration system complete heat interchange in the water side heat interchanger, the water system comprises a water inlet tube, a water outlet tube and a water tank communicated with the water side heat interchanger, an inflow water regulation mechanism is communicated with the front end of the water inlet tube, and the inflow water regulation mechanism is respectively communicated with a water supply tube of tap water and the bottom part of the water tank. When water temperature is low in winter, the hot water is led to the inflow water regulation mechanism where the hot water is mixed with the cold water according to a certain proportion into warm water and then the warm water enters the water side heat interchanger, thus effectively increasing the inflow temperature of the water side heat interchanger of the machine set, increasing flow amount entering the machine set, so that the temperature of the inflow water in the water side heat interchanger is moderate, the operation of the machine set is stable and reliable.
Description
Technical field:
The present invention relates to a kind of air-source heat pump hot water group, particularly relate to a kind of inflow temperature and make unit be operated in the middle temperature directly-heated type air-source heat pump hot water group of normal temperature state by control unit water-side heat.
Background technology:
Mostly the air-source heat pump hot water group is to be made up of compressor, air side heat exchanger, blower fan, water-side heat, restricting element, intelligence control system and corresponding water system, its operation principle is that cold-producing medium evaporates the airborne heat of absorption in air side heat exchanger, compressed machine compression back condensation heat release in water-side heat, the heat that absorbs is discharged in the water system, provide the domestic hot-water to the user, this water mode COP value that heats is high, energy-conserving and environment-protective, and overall economic efficiency is good.
Existing circulation heated type air-source heat pump hot water group operation principle as shown in Figure 1, itself because self, have following outstanding problem:
1, leaving water temperature is limited, can not satisfy high water temperature requirement
There is a limit value in existing freon refrigeration system to condensation temperature, so the water tank final temperature of circulation heated type air-source heat pump hot water group can not surpass a certain limiting value (being generally 50 ℃), when temperature surpasses this value, the pressure and temperature of unit sharply raises, unit cisco unity malfunction even cause the accident.
2, the water tank temperature fluctuation is big, has reduced the dischargeable capacity of water tank, the comfortableness that influence is used
The moisturizing of circulation heated type air-source heat pump hot water group is directly in water tank, make water temperature reach instructions for use gradually through unit circulation heating again, when this just causes unit just to open, the water tank water temperature is very low, along with the operation water temperature of unit raises gradually, reach instructions for use up to water temperature, thereby the stand-by period is longer.In addition, in use be the guaranteed water level requirement, cold water is directly mended water tank and is mixed with high-temperature water in the water tank, and the water tank water temperature is descended, and finally can not use, and has reduced the dischargeable capacity of water tank, influences the comfortableness of use.
Summary of the invention:
For addressing the above problem, the invention provides a kind of in warm directly-heated type air-source heat pump hot water group, under the prerequisite that guarantees high leaving water temperature, make unit enter the nominal operation state rapidly, avoided the thermal loss in the start-up course, improve heating efficiency, thereby solved the difficult problem of air-source heat pump hot water group storage tank miniaturization.
Technical solution problem of the present invention adopts following technical scheme:
Warm directly-heated type air-source heat pump hot water group in a kind of, comprise the refrigeration system of forming by compressor, air side heat exchanger, blower fan, restricting element, water-side heat, the recirculated water of water system and the medium of refrigeration system are finished heat exchange in water-side heat, described water system comprises water inlet pipe, outlet pipe and the water tank that is communicated with water-side heat, is communicated with tap water supply pipe and water tank bottom respectively at the front end connection one water inlet governor motion of described water inlet pipe, described water inlet governor motion.
Also be provided with on the water inlet pipe between water inlet governor motion and water-side heat and can regulate the electronic valve that enters discharge in the water-side heat.
Described outlet pipe is communicated with water tank at the top of water tank.
Described water tank is the non-bearing type water tank.
Compared with the prior art, beneficial effect of the present invention is embodied in:
When water temperature in winter is low, the hot water in the storage tank guided in the water governor motion and cold water enters water-side heat after being mixed into warm water by a certain percentage again, thereby improve unit water-side heat inflow temperature effectively, strengthened the discharge that enters unit.Make that the inflow temperature of water-side heat is moderate, unit operation is reliable and stable; 2, under the condition of low in the winter time water temperature, low ambient temperature, shorten the unstable working state process in compressor start stage, make unit enter the nominal operation state rapidly, the energy loss the startup stage of the minimizing; 3, owing to improved the water inlet condition of water-side heat, the discharge of turnover unit is bigger, also is that the thermal capacity of water system is big, and system is easy to regulate, and can obtain higher leaving water temperature; 4, be easy to realize the miniaturization of storage tank, the insulation energy consumption that help reducing cost, save installing space, reduces storage tank.
Description of drawings:
Fig. 1 is existing circulation heated type air-source heat pump hot water group structural representation.
Fig. 2 is a structural representation of the present invention.
Number in the figure: 1 compressor, 2 air side heat exchangers, 3 blower fans, 4 restricting elements, 5 water-side heats, 6 water inlet pipes, 7 outlet pipes, 8 water tanks, 9 water inlet governor motions, 10 feed pipes, 11 electronic valves, 12 water pumps.
The specific embodiment, non-limiting examples is as described below:
Embodiment: shown in Figure 2, the middle temperature directly-heated type air-source heat pump hot water group of present embodiment, comprise refrigeration system and water system, refrigeration system is made up of compressor 1, air side heat exchanger 2, blower fan 3, restricting element 4, water-side heat 5, and the recirculated water of water system and the medium of refrigeration system are finished heat exchange in water-side heat 5.Water system is by the water inlet pipe 6 that is communicated with water-side heat 5, the outlet pipe 7 of drawing in water-side heat, outlet pipe is communicated with the top of non-bearing type water tank water tank 8, hot water being injected the top in the water tank 8, be communicated with a water inlet governor motion 9 at the front end of water inlet pipe 6, this water inlet governor motion 9 is communicated with the bottom of tap water supply pipe 10 and water tank 8 respectively.
