Abstract
The invention discloses a stepless constant-temperature direct water yielding air source water heater comprising a compressor, a condenser and an evaporator, wherein, the condenser is connected with the pipeline of the compressor; the compressor is a DC variable frequency compressor adopting environmental-friendly coolant, a stepless speed change fan is installed in the evaporator, and the condenser is a long-range coaxial heat exchanger composed of a coolant pipeline and a water medium pipeline; two ends of the coolant pipeline are respectively connected with the DC variable frequency compressor and the evaporator pipeline; the water medium pipeline is provided with a stream sensor which is connected with the control system of the DC variable frequency compressor. The invention adopts theDC variable frequency compressor and the environmental-friendly coolant, so that the invention has small impact on a power grid during starting; environmental-friendly coolant is harmless to the ozone layer and directly heats to a temperature suitable for human bodies, which prevents skin from being scalded. The stream sensor controls the starting and halting of the compressor without storing water and preheating, and energy saving effect is over one time more than that of a common compressor; the machine set has higher working energy efficiency ratio in the lower-temperature zone for a longterm, and the machine set has longer machine set service life.
Description
Technical field
The present invention 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 invention 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 solution adopted for the present invention to solve the technical problems 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 improvement of the technical scheme of the present invention, 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 invention has the beneficial effects as follows: the present invention 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
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present invention;
Fig. 2 is the cross-sectional schematic of heat exchanger.
The specific embodiment
With reference to Fig. 1, Fig. 2, stepless constant-temperature direct water yielding air source water heater disclosed by the invention, 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 invention 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 present invention adopts DC frequency-changeable compressor and environmental protection refrigerant, it has than friendship The energy-conservation characteristics of stream invariable frequency compressor are impacted little to electrical network during starting; Environmental protection refrigerant pair Ozone layer is harmless, and is directly to be heated to suitable human body temperature, can prevent from scalding skin Skin; By current inductor control compressor start and shutdown, open during water during use Machine, water is not then shut down, need not the water storage preheating, energy-saving effect is than existing common compression Machine is high more than 1 times; Unit is for a long time higher in low-temperature space work Energy Efficiency Ratio, unit durability Longer.
