Abstract

The utility model relates to a solar pump-free cold and hot water machine set, particularly to a central air conditioner which uses solar energy as a power source, has a heating function, a refrigerating function, and a function of providing living sanitary hot water all the year around, and has the advantages of high efficiency and low energy consumption. The utility model has the structure that a shower pipe in an evaporating and absorbing device is composed of 18 copper pipes which are respectively and correspondingly assembled in holes uniformly distributed on a liquid distributing disk in order to ensure evaporation and absorption, and lithium bromide is used as absorbent. The utility model has the advantages of reasonable structure, full use of solar energy source, high efficiency, energy saving, low one time investment, no pump, no noise and no pollution. The utility model is an ideal central air conditioner used for refrigeration in summer, heating in winter, and providing living sanitary hot water for villanettes of the urban periphery.

Description

Solar pump-free type hot and cold water unit

It is a kind of heating, refrigeration and annual central air conditioning that the high efficiency low energy consumption of living-hygienic hot water is provided of integrating of power source that the utility model belongs to solar energy.This unit is to make full use of the solar thermal collector thermal-arrest, makes water temperature reach 80 ℃～100 ℃, drives circulating operation as thermal source, is the hot and cold water unit of absorbent pump-free type with the lithium bromide.

Continuous development along with the kownledge economy and the new and high technology of society, become trend of the times for energy savings, for saving natural other energy, make full use of the solar thermal collector cumulative, can obtain hot water about 90 ℃ by heat collector, make cool, the warming of this unit collection summer system, and provide annual living-hygienic hot water to be achieved.At the cloudy cloudy day or under the situation of sunlight deficiency, this unit has small-sized fuel oil, gas fired-boiler, as auxiliary thermal source.In view of the foregoing, the inventor develops out a kind of solar energy that utilizes and is thermal source, is the hot and cold water unit of absorbent pump-free type with the lithium bromide, is very necessary.

The purpose of this utility model: providing a kind of solar energy that utilizes to be circulating operation, is the hot and cold water unit of absorbent pump-free type with the lithium bromide.It is to make full use of the solar thermal collector heat build-up, can obtain hot water about 90 ℃ by solar thermal collector, makes this machine consist of a kind of heating, refrigeration and annual central air conditioning that the high efficiency low energy consumption of living-hygienic hot water is provided of integrating.When weather changed the sunlight deficiency, this unit had small-sized fuel oil, combustion gas, electric boiler, as supplementary energy.

The utility model relies on following technical proposals to realize: a kind of solar pump-free type hot and cold water unit, mainly by evaporation---absorber, condenser, separator, generator, heat exchanger, raise liquid pipe, solar thermal collector, heat reservoir and standby small-sized fuel oil, combustion gas, the electric boiler part constitutes, it is characterized in that, in evaporation---the shower in the absorber is made up of 18 copper pipes, correspondence is assemblied on the cloth liquid dish in the equally distributed hole respectively, to guarantee that evaporation absorbs, and makes liquid spraying even; And to have adopted lithium bromide be absorbent; The uniform copper pipe that is provided with enhance heat around the heat-transfer pipe in generator to increase area of dissipation, guarantees heat exchange; And be provided with one and raise the liquid pipe, to guarantee the motive force of steam bubble, liquid is gone straight up to separator; In separator, adopt two steel plate washers composition separation chambers, labyrinth are set, only to allow gas pass through, make solution obtain finite concentration; This unit be a kind of be that power source drives moving circulating operation with solar energy, be the hot and cold water unit of absorbent pump-free type with the lithium bromide.

This working principle of said set: when solution is produced solution and refrigerant vapour mixture by the hot water heating in generator (4), because bubble effect, rise along raising liquid pipe (6), in the separation chamber, isolate concentrated solution and refrigerant vapour, be scattered down to absorber (1) upper end through heat exchanger (5), absorption becomes weak solution behind the next water vapour of evaporimeter, behind the Returning heat-exchanger (5), enter generator (4) again and be heated.The isolated refrigerant vapour from the separation chamber is condensed in condenser (2) on the other hand, condenses into water as refrigerant, be scattered down to evaporimeter through U type pipe and be evaporated, evaporation process absorbs the chilled water heat, the chilled water outlet temperature is reduced to is about about 9 ℃, thereby produce refrigeration.

Advantage of the present utility model:

1. this set structure is reasonable, and modern design, compactness make full use of solar source, and unit operation is efficient, energy-conservation, and the disposable input expense of equipment is low, uses economical.No pump, noiseless, non-environmental-pollution are that the surrounding city villanette is used for freezing summer, warming and the desirable central air conditioning of living-hygienic hot water in one is provided.

This unit be a kind of be that power source drives moving circulating operation with solar energy, be absorbent pump-free type hot and cold water unit with the lithium bromide, pollution-free, nuisanceless.

3. in order to make this unit in cloudy cloudy day or normally operation under the situation of sunlight deficiency, this unit has small-sized fuel oil, combustion gas, electric boiler, as auxiliary thermal source.

Below in conjunction with Figure of description, technical characterictic of the present utility model and embodiment are described further.
