Technical field
The utility model relates to a kind of hot-water heating system, relates in particular to a kind of serial solar energy heat pump hot-water system.
Background technology
As everyone knows, solar energy is the main source of all energy on the earth, also is a kind of free of contamination, safe, inexhaustible natural energy resources.Solar water heater is converted into heat energy with clean energy resource solar energy, for various occasions provide hot water.At present, solar water heating system commonly used mainly is comprised of ordinary solar heat collector and auxiliary electrical heater, the stability that tends to be subject to weather effect and can not keeping system, if the situations such as water when meeting with such as night, sleet, cloudy day, nearly all can adopt inefficient auxiliary electrical heater to keep normal operation, system economy is just had a greatly reduced quality.
Earth source heat pump is a kind of highly effective energy-conserving environmental-protecting type energy utilization technology that utilizes the underground shallow layer geothermal energy resources.By inputting a small amount of high-grade electric energy, can realize the transfer of energy from low-temperature heat source to high temperature heat source.It can replace boiler that the low-grade energy in the ground energy " is got ", after the raising temperature, and hot water supply system.But the earth source heat pump long-time running will make Soil Temperature Field can not get efficient recovery, and evaporating temperature and condensation temperature fluctuation are larger, and the source pump operational efficiency is lower.
Therefore, if solar energy and earth source heat pump can be built together, " learn from other's strong points to offset one's weaknesses; rationally supply ", design a cover composite solar pump hot-water heating system, so this novel energy supplyystem not only will have separately the characteristic of peculiar economy, environmental protection, also will have obvious energy-saving potential.
The utility model content
The purpose of this utility model is to provide a kind of efficient, energy-saving and environmental protection, stable serial solar energy heat pump hot-water system.
The technical scheme that the utility model adopts is: a kind of serial solar energy heat pump hot-water system, it is composed in series by solar water heating system and heat pump hot-water system two parts, described solar water heating system comprises solar thermal collector, water tank, circulating pump, described heat pump hot-water system comprises compressor, choke valve, condenser, evaporimeter, boiler, and the evaporimeter of described heat pump hot-water system is installed in the water tank of described solar water heating system.
Technique effect of the present utility model is as follows: (1) the utility model provides hot water by solar water heating system and heat pump hot-water system series connection, and both learn from other's strong points to offset one's weaknesses, and complement each other, and can give full play to both energy-saving potentials, make better energy conservation.When solar energy was not enough, heat pump performance Main Function guaranteed Systems balanth, guarantees the hot water supply; When the solar energy abundance, when illumination is strong, by solar water heating system performance Main Function, guarantee the hot water supply.
(2) the serial solar energy heat pump hot-water system is a kind of novel auxiliary type hot water technique, and it combines solar energy utilization technique and heat pump techniques, can also solve the frosting problem under the heat pump low temperature, has improved the reliability of whole system.Use solar energy as low order heat source for heat pump when outdoor low temperature, the average coefficient of performance in heating of heat pump can increase, and the energy conservation characteristic of heat pump will further improve.
(3) the utlity model has the advantage of clean environment firendly, energy-efficient, reusable edible.

In the accompanying drawing, 1-solar heat collector, 2-circulating pump, 3-water tank, 4-evaporimeter, 5-compressor, 6-choke valve, 7-condenser, 8-boiler.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of serial solar energy heat pump hot-water system, it is composed in series by solar water heating system and heat pump hot-water system two parts.Described solar water heating system comprises solar thermal collector 1, water tank 3, circulating pump 2, described heat pump hot-water system comprises compressor 5, choke valve 6, condenser 7, evaporimeter 4, boiler 8, and the evaporimeter 4 of described heat pump hot-water system is installed in the water tank 3 of described solar water heating system.
The solar water heating system operation principle is as follows: under the effect of circulating pump 2, cold water enters solar thermal collector 1, solar thermal collector 1 absorbs solar energy and is converted into heat energy, make cold water become hot water, hot water flows into water tank 3 through pipeline, with evaporimeter 4 heat exchanges occur, heat energy is passed to working medium in the heat pump in water tank 3.
The heat pump hot-water system operation principle is: the working medium in the heat pump drives by compressor 5, in evaporimeter 4, absorb heat and airborne heat (or the heat energy in the source, ground) in the solar water heating system water tank 3, become high-temperature low-pressure gas, become high temperature and high pressure gas after compressed machine 5 pressurizations, then enter condenser 7 and emit latent heat of phase change, carry out heat exchange with the water in the boiler 8, water is heated.Working medium in the condenser 7 becomes cryogenic high pressure liquid, after this becomes low-temp low-pressure liquid through choke valve 6 adiabatic throttlings again and returns the low-temperature heat source place and enter next time operation cycle.
Described series connection refers to the mode that heat transmits, and solar energy is converted into heat energy, and the heat energy in the solar water heating system and the heat energy in the heat pump converge, and to boiler 8, whole energy transmission is series flow through heat pump " pumping ".
