Description
Technical field
The utility model relates to a kind of hot water machine, particularly a kind of stepless constant-temperature direct water yielding air source heat pump machine.
Background technology
What traditional air source water heater adopted is to exchange invariable frequency compressor and common refrigerant, exchange invariable frequency compressor and when starting, electrical network is had obvious impact, and common refrigerant is harmful to ozone layer, and traditional air source water heater need utilize attemperater to store the hot water that preheats to design temperature, need during use and cold water mix, otherwise have the danger of scalded skin; The hot water that traditional air source water heater of while needs long-term work just to have capacity uses, so its energy-saving effect is undesirable.
Summary of the invention
In order to overcome the deficiencies in the prior art, when the utility model provides a kind of the starting to electrical network impact less, the stepless constant-temperature direct water yielding air source heat pump machine of environmental protection, good energy-conserving effect.
The technical scheme that its technical problem that solves the utility model adopts is:
Stepless constant-temperature direct water yielding air source water heater, comprise compressor, the condenser and the evaporimeter that are connected with the compressor pipeline, it is characterized in that described compressor is the DC frequency-changeable compressor that adopts the environmental protection refrigerant, the infinitely variable speeds blower fan is installed in the evaporimeter, the coaxial heat exchanger of long-range that described condenser is made up of refrigerant pipe and aqueous medium pipeline, the two ends of refrigerant pipe are connected with evaporator pipeline with DC frequency-changeable compressor respectively, the current inductor is installed on the aqueous medium pipeline, and described current inductor is connected with the control system of DC frequency-changeable compressor.
As the utility model improvement of the technical scheme, be equipped with from defrosting device in the described evaporimeter.
Above-mentionedly can adopt electric heater from defrosting device.
On above-mentioned refrigerant pipe and the pipeline that evaporimeter is connected electric expansion valve is installed.
The beneficial effects of the utility model are: the utility model adopts DC frequency-changeable compressor and environmental protection refrigerant, and it has than exchanging the energy-conservation characteristics of invariable frequency compressor, impacts little to electrical network during starting; The environmental protection refrigerant is harmless to ozone layer, and is directly to be heated to suitable human body temperature, can prevent scalded skin; By current inductor control compressor start and shutdown, start shooting during water during use, water is not then shut down, need not the water storage preheating, and energy-saving effect is higher more than 1 times than existing common compressor; Unit is higher in low-temperature space work Energy Efficiency Ratio for a long time, and unit durability is longer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the cross-sectional schematic of heat exchanger.
The specific embodiment
With reference to Fig. 1, Fig. 2, the disclosed stepless constant-temperature direct water yielding air source water heater of the utility model, comprise compressor, the condenser 2 that is connected with the compressor pipeline and evaporimeter 3, wherein compressor is the DC frequency-changeable compressor 1 that adopts the environmental protection refrigerant, the environmental protection refrigerant can directly be buied from market, and infinitely variable speeds blower fan 4 is installed in evaporimeter 3.The coaxial high-performance heat exchanger of long-range that condenser 2 is made up of refrigerant pipe 5 and aqueous medium pipeline 6, the two ends of refrigerant pipe 5 are connected with evaporimeter 3 pipelines with DC frequency-changeable compressor 1 respectively, current inductor 7 is installed on aqueous medium pipeline 6, and current inductor 7 is connected with the control system of DC frequency-changeable compressor 1.
In evaporimeter 3, be equipped with from defrosting device, should can adopt electric heater 8 from defrosting device, so that the time spent melts frost and oven dry from evaporimeter, shorten the defrost time, do not need the water tank thermal source to assist, and under low temperature environment operation unit opening electric heater simultaneously when adding hot water, the heat of electric heater is passed to the condenser heat release through evaporimeter, the heat that electric heater is sent not only can prevent frosting, and unit is worked under the environment of low temperature more.
On refrigerant pipe 5 and pipeline that evaporimeter 3 is connected, electric expansion valve 9 is installed.
Operation principle of the present utility model is: use water valve when opening, the current inductor detects current, and the generation electrical signal transfer is to the control system of DC frequency-changeable compressor, control system control DC frequency-changeable compressor starts, compressor accelerates to the frequency of the heating leaving water temperature of setting from low frequency, simultaneously blower fan and electric expansion valve and compressor precision-fit; When closing when using water valve, the current inductor detects less than current, and produces the control system of electrical signal transfer to DC frequency-changeable compressor, steadily shuts down after control system control DC frequency-changeable compressor is reduced to low frequency.
Because the utility model adopts DC frequency-changeable compressor and environmental protection refrigerant, it has than exchanging the energy-conservation characteristics of invariable frequency compressor, impacts little to electrical network during starting; The environmental protection refrigerant is harmless to ozone layer, and is directly to be heated to suitable human body temperature, can prevent scalded skin; By current inductor control compressor start and shutdown, start shooting during water during use, water is not then shut down, need not the water storage preheating, and energy-saving effect is higher more than 1 times than existing common compressor; Unit is higher in low-temperature space work Energy Efficiency Ratio for a long time, and unit durability is longer.
