Abstract
An integrated hot water system of a solar heat pump comprises a group of solar thermal collectors, a thermal insulation circulating water tank, an air source heat pump and a delivery water pipe, and is characterized in that the delivery water pipe is used for connecting the solar thermal collectors, the thermal insulation circulating water tank and the air source heat pump; the solar thermal collectors are used for heating water; the delivery water pipe conveys hot water to the thermal insulation circulating water tank; and then the hot water is conveyed to water consumption points for use of users through the thermal insulation water tank. In overcast and rainy days or in winter with relatively lower ambient temperature, insufficient solar resource and water temperature lower than set temperature, the air source heat pump is used for auxiliary heating to keep the integrated system of hot water supply in normal status. During operation of the system, the utilization rate of solar energy absorbed by the thermal collectors is close to 100%, and the power consumption of auxiliary heating only accounts for 7-14% of the total energy consumption of the system. Compared with the hot water system of conventional energy sources, the integrated hot water system saves energy by at least over 85% and is remarkable in energy-saving effect.
Description
Technical field
The utility model relates to a kind of solar water heating system, the pump integrated hot-water heating system of specifically a kind of solar heat.
Background technology
The development and utilization of solar energy at present, extensively paid attention to, solar water heater is of a great variety, various informative, but the subject matter that existing solar water heater exists is that the heat collector of suitable high latitude cold district use in winter is few, correlative study is also few, if region temperature is lower, radiation loss is big and the freeze injury problem arranged, general solar water heater is stopped using winter, other cloudy daies in season all the time according to the time do not have the hot water supply yet, this brings very big inconvenience to the user, has also reduced the service efficiency of solar energy, if use electrical heating auxiliary, cause power consumption many, the expense height.How to ensure that daily life to the demand of hot water, economical and practical again, becomes a technical barrier that needs to be resolved hurrily.
Summary of the invention
The air source heat pump operation principle: the air source heat pump compressor sucks the low-temp low-pressure gas refrigerant from evaporimeter, by acting cold-producing medium is compressed into high temperature and high pressure gas, high temperature and high pressure gas enters condenser and water heat-shift, be condensed into liquid and discharge a large amount of heats at condenser, water absorbs its liberated heat and elevates the temperature.The highly pressurised liquid that is condensed is inhaled in the compressor again and compresses after the throttling step-down, circulation so repeatedly, thus produce hot water.The main thermal source of air source heat pump is from ambient air, and power consumption only is equivalent to 1/4 of electric heater power consumption.Air source heat pump is provided with: 1, A.T.C (hot water temperature who produces is generally at 45 ℃～60 ℃) and automatic water supplement function; 2, automatic defrosting device can move main frame under subzero environment temperature more than 5 ℃, water temperature still reaches 55 ℃ under the adverse weather condition; 3, design has constant temperature and regularly reclaims the cold water control system, when water temperature is lower than the recovery time of set temperature value or setting, system can be recovered to insulation cyclic water tank bottom to the cold water in the pipe automatically, sends heat collector again to and reheats, and this mode can guarantee round-the-clock heat supply water.
The purpose of this utility model provides a kind of pump integrated hot-water heating system of a kind of solar heat that is suitable for working in the low temperature environment.Can satisfy the system of bath center, hotel, school, family's year-round provision hot water, the pump integrated hot-water heating system of solar heat is direct with the auxiliary firing equipment of air source heat pump as solar energy system, directly is heated to be the master, is heated to be auxilliary integrated hot-water heating system with air source heat pump with solar thermal collector.This system adopt a kind of novel, with low-temperature solar energy auxiliary net for air-source heat pump units and solar thermal collection system combination, solar energy and heat pump be auxiliary thermal source each other, utilize solar energy to greatest extent, solve rainy weather and the winter environment temperature is lower, the hot water supply when solar energy resources is not enough, accomplish the whole year, 45 ℃～60 ℃ hot water of round-the-clock supply.
The technical scheme that its technical problem that solves the utility model adopts is: the pump integrated hot-water heating system of a kind of solar heat, it is characterized in that: this system directly is heated to be the master, is heated to be auxilliary integrated hot-water heating system with air source heat pump with solar thermal collector, this system is with carrying water pipe that solar thermal collector, insulation cyclic water tank are connected with air source heat pump, with solar thermal collector with the water heating, by carry water pipe with delivery to the insulation cyclic water tank, be transported to respectively by the insulation cyclic water tank and use for the user again with water spot.When rainy weather and winter environment temperature are lower, solar energy resources deficiency, water temperature are lower than when temperature is set, and guarantee the integral system of hot water supply with the auxiliary heating of air source heat pump.
The pump integrated hot-water heating system of a kind of solar heat, owing to adopt above-mentioned design to have the following advantages: according to the solar radiation data in the most of area of northern China, per day that heat is determined the area of solar thermal collector according to the average heat consumption of sanitary hot water system and solar thermal collector, the direct heating of solar energy can be satisfied annual 60～80% hot water demand, all the other 20～40% heats are by the net for air-source heat pump units supply of the auxiliary heating of solar energy, the average COP of heat pump can reach 3.0, be that its heat of supplying has the solar energy and the air heat energy that can not directly utilize from heat collector more than 65%, in service in system, the solar energy utilization ratio that heat collector absorbs is near 100%, the power consumption of auxiliary heating only accounts for 7～14% of system's total energy consumption, energy-conservation at least more than 85% than the hot-water heating system of conventional energy resource, energy-saving effect is remarkable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Accompanying drawing is the utility model structural representation
Among the figure 1, solar thermal collector, 2, the insulation cyclic water tank, 3, air source heat pump, 4, carry water pipe,
5, use water spot.
The specific embodiment
As shown in the figure among the embodiment, with carrying water pipe 4 that solar thermal collector 1, insulation cyclic water tank 2 are connected with air source heat pump 3, with solar thermal collector 1 with water heating, by carry water pipe 4 with delivery to insulation cyclic water tank 2, be transported to each by attemperater again and use water spot 5 to use for the user.When rainy weather and winter environment temperature are lower, solar energy resources deficiency, water temperature are lower than when temperature is set, and guarantee the hot water supply with air source heat pump 3 auxiliary heating.
Embodiment 1
Solar thermal collector heating domestic hot-water; At good fine day at most of sunshine, by the solar thermal collector heat hot water, system controller is controlled according to the temperature of solar thermal collector and boiler, and the hot water of solar thermal collector heating is standby by carrying water pipe to be transported to the insulation cyclic water tank.
Embodiment 2
