Description
Technical field
The utility model relates to earth-source hot-pump system, relate in particular to a kind of automatic control system of earth-source hot-pump system, by adopting perfect automatic control system, having realized the entirely automatic control of source heat pump system and the efficiency of system detects, be conducive to improve operational efficiency and the operation stability of earth-source hot-pump system, realize the automatic control to whole system.
Background technology
Along with development and the growth in the living standard of economic society, people are also more and more higher to the requirement of inhabitation, comfortable working environment, China's conversion throughout the year in addition, and the whole year temperature difference is larger, and people's adaptability has been proposed to higher requirement.And the appearance of air-conditioning has solved all-year temperature difference problem, can be according to the conversion of external environment condition, by heat supply and refrigeration, people are lived and the indoor environment of working keeps the temperature of a balance, allow people feel comfortable.So air-conditioning becomes indispensable a kind of instrument that regulates temperature in people's live and work.
In China, current air-conditioning is main mainly with electric energy greatly, will expend a large amount of electric energy every year.In addition, current air-conditioning is air source heat pump air-conditioner mostly, and in the course of work, indoor waste heat or cold are discharged in outdoor air, in the time that city is used air-source heat pump air conditioning system in a large number, to cause summer environment temperature to raise, winter environment temperature reduces, although indoor comfortable, but outdoor severe, be the comfortable to destroy outdoor environment as cost of indoor environment, in the long run, be unfavorable for people's health.And due to the outside heat extraction of traditional air-conditioning, when outdoor temperature is lower, air-conditioning work is normal, in the time that outdoor temperature is higher, air-conditioning is difficult to outside heat extraction, causes operating efficiency to reduce, and refrigeration declines.
In the problem period that becomes countries in the world extensive concern in the energy and environmental problem, the power saving of air-conditioning can not be ignored, and the energy consumption that how to reduce air-conditioning becomes one of key technology solving energy problem.Due to scientific and technical development, the utilization of new science and technology is more and more, and the space of development is also increasing, wherein earth source heat pump is just conducive to alleviate for the technology of air-conditioning system the energy and the environmental crisis that air-source heat pump air conditioning system brings.
This is due under shining in the radiation of the sun, the earth becomes huge " memory " of solar energy, in the water body of earth's crust shallow-layer and soil, a large amount of clean regenerative resources are stored, the solar energy of the nearly half that the earth obtains is all gathered in this, is called the geothermal using energy (being called for short source, ground).Utilize the energy saving and environment friendly air-conditioning of underground shallow layer geothermal energy resources (as underground water, soil or surface water etc.) and geothermal heat pump air-conditioning system is exactly one, in winter, source pump absorbs heat from source, ground, heats to building; In summer, source pump is discharged into source, ground from indoor absorption heat transfer, realizes the refrigeration of building.Geothermal heat pump air-conditioning system, there are a lot of advantages, for example energy-saving and emission-reduction, it utilizes source, ground, can not cause the variation of outside air temperature, not waste discharge, waste gas, waste residue, its course of work is a cyclic process, summer in winter compensates mutually, can make the heat of the earth substantially maintain balance, belongs to clean regenerative resource; In addition, source, ground has replaced boiler and the cooling tower of conventional central air-conditioning, can freeze, warm, again can be for user provides hot water, and a tractor serves several purposes.
Although geothermal heat pump air-conditioning system has significant superiority, current geothermal heat pump air-conditioning system utilization rate is also not high, one of them reason is because the automatic controlling system precision that geothermal heat pump air-conditioning system adopts is at present not high, well tracking system is loaded and is moved, particularly in the control of temperature, also do not possess adaptive ability, be difficult to meet comfortableness and energy-conservation requirement.In addition, in current ground-source heat pump central air-conditioning, the design of control system and the type selecting of pump equipment all leave certain leeway, and in actual use, due to the variation of seasonal factor, day and night temperature and customer charge, within the overwhelming majority time, actual air-conditioning load is all low more than design (calculated) load, therefore, current most of air-conditioning all moves under sub-load, in light running state, operating efficiency is lower, has wasted the energy.
Therefore, improve energy utilization rate, it is one of important channel solving China's energy and environment problem that Devoting Major Efforts To Developing utilizes regenerative resource, a kind of both energy-saving and emission-reduction, sustainable development path free from environmental pollution and utilize earth source heat pump exploitation shallow layer geothermal energy, be worth it to be better controlled, better to apply.
