The utility model relates to an air-water dual-source water heater. The air-water dual-source water heater comprises a compressor, a condenser, an expansion valve, an evaporator and a fan; wherein the compressor, the condenser, the expansion valve and the evaporator are sequentially connected into a heating power circulation loop by pipelines; and a heat-transfer working medium carries out circulation running in the loop. The air-water dual-source water heater is characterized in that the evaporator is composed of an air source evaporator and a water source evaporator, and the fan acts on the air source evaporator. The better scheme is that the air-water dual-source water heater further comprises a pressure switch used for controlling the fan. The air-water dual-source water heater is safe as well as energy-saving to be used, leads low using cost, and can be used in both high-temperature and low-temperature environments.
Description
Technical field
The utility model relates to water heater, particularly air water double source water heater.
Background technology
Water heater commonly used comprises solar water heater, electric heater, gas heater, air source water heater.The shortcoming of solar water heater is: reach in all weather of the year and use, must electricity or combustion gas be arranged as auxilliary heat on the date that does not have the sun, so it is regional fully inadequately at sunshine, the annual efficient of solar water heater is got involved in auxilliary heat, and at the city high residential building, it is also unrealistic that each household is installed solar water heater.The shortcoming of electric heater is: convert high-grade electric energy to low-grade heat energy, it is the waste of another energy, and use cost is also higher under the electricity price condition with higher, and also there is secret worry in its security performance, domestic existing a few cause electric heaters electric leakages and cause the accident of death of child.The shortcoming of gas heater is dangerous, report is arranged when using the dead example of gas heater anthracemia also, and the operating cost of gas heater is equally matched with electric heater, and use cost is also higher.Air source water heater, comprise compressor, condenser, expansion valve, air source evaporimeter and fan, wherein compressor, condenser, expansion valve and air source evaporimeter connect into the thermodynamic cycle loop by pipeline successively, heat-transfer working medium is circular flow in the loop, fan acts on air evaporator, the advantage of this air source water heater is energy-conservation, and security performance is good again, shortcoming is: efficient height when temperature is high, efficient was low when temperature was low, low when icing at temperature, system can not work or efficient is crossed low and can't effectively be heated basically.
The utility model content
The technical problems to be solved in the utility model is to carry a kind of safe, energy-conservation, air water double source water heater that use cost is lower of arch, not only can use under the higher environment of temperature, also can use under the lower environment of temperature.
For solving this technical problem, the technical solution adopted in the utility model is as follows:
Air water double source water heater, comprise compressor, condenser, expansion valve, evaporimeter and fan, wherein compressor, condenser, expansion valve and evaporimeter connect into the thermodynamic cycle loop by pipeline successively, heat-transfer working medium is circular flow in the loop, it is characterized in that: described evaporimeter is made up of air source evaporimeter and water source evaporimeter, and described fan acts on air source evaporimeter.
Described water source evaporimeter is connected between air source evaporimeter and the compressor.
Also can be that air source evaporimeter is connected between water source evaporimeter and the compressor.
Preferable scheme is, also comprises the pressure switch of controlling described fan, and the probe of this pressure switch is located at the air entry of compressor.
The probe of this pressure switch also can be located on the pipeline that connects expansion valve, air source evaporimeter, water source evaporimeter, compressor.
After adopting technique scheme, owing to not only be provided with air source evaporimeter but also be provided with the water source evaporimeter in this water heater, under the lower environment of temperature, during lower the or cisco unity malfunction of air source evaporator operation efficient, use the water source evaporimeter, can use heating installation, the thermal source of spent hot water of living as the water source evaporimeter.Under the higher environment of temperature, air source evaporimeter operate as normal, and also when air source evaporimeter placed within doors, it can provide air conditioner refrigerating and dehumidifying for the room when heating water.This like this air water double source water heater both had been adapted at that work also is adapted at working under the hot environment under the low temperature environment, can keep higher running efficiency throughout the year.Because the probe that the control pressure switch of fan and this pressure switch are installed is located at the air entry of compressor, when the compressor air suction mouth pressure was lower than setting pressure, pressure switch was connected, the fan operation, and air source evaporimeter begins operate as normal; When the air entry pressure of compressor was higher than setting pressure, pressure switch disconnected, and fan stops, and air source evaporator stops operation is realized the automatic control of air source evaporimeter like this by pressure switch.Because this water heater obtains thermal source from air, heating installation, life spent hot water, and does not have noxious gas emission, does not place the thermal resistance of water, there is not the danger of electric leakage, relatively environmental protection, energy-conservation, safe in utilization.
Description of drawings
Fig. 1 is the utility model air water double source water heater schematic diagram.
The specific embodiment
Referring to Fig. 1:
Air water double source water heater, comprise compressor 1, condenser 2, expansion valve 3, air source evaporimeter 4, act on the fan 5 of air source evaporimeter 4, water source evaporimeter 6, pressure switch 7, wherein compressor 1, condenser 2, expansion valve 3, air source evaporimeter 4, water source evaporimeter 6 connects into the thermodynamic cycle loop by pipeline 8 successively, heat-transfer working medium is circular flow in the loop, the operation of pressure switch 7 control fans 5, and the probe of pressure switch 7 is located at the air entry of compressor 1.
Certainly, air source evaporimeter 4 also can be connected between water source evaporimeter 6 and the compressor 1.The probe of pressure switch 7 also can be located on the pipeline that connects expansion valve 3, air source evaporimeter 4, water source evaporimeter 6, compressor 1, when pipeline inner pressure is lower than setting pressure, pressure switch 7 is connected, fan 5 operations, air source evaporimeter 4 beginning operate as normal; When pipeline inner pressure was higher than setting pressure, pressure switch 7 disconnected, and fan 5 stops, and air source evaporimeter 4 quits work.
Use this air water double source water heater, producing under hot water amount's on year-on-year basis the condition, the power consumption of air water double source water heater can reach and only be equivalent to 20% to 30% of common electrical water heater power consumption, and use cost is lower.
