Abstract
The invention provides a combined water heat-pump heating system. In a system with a plurality of water supply heat-pump units, the evaporimeter of each unit are connected parallelly to get low-temperature heat-source water of same temperature; the condensers of each two water supply heat-pump units are connected in series; after the return water for low-temperature heating enters into the condenser of the first unit, the temperature rises to certain extent, then the return water enters into the condenser of the second unit, and the temperature rises again; then heat is supplied to the building through such energy releasing system as the circulation pumps and pipelines, etc. Each unit in the system gets high efficiency, the heating circulation water realizes high temperature difference and low flow, the investment and operation cost for such equipment as the circulation water pump and heating pipelines, etc. are reduced. The system is an energy-saving and efficient system.
Description
Affiliated technical field
When the present invention relates to many water source heat pump units combined heats, the efficient combined-type system of the parallel connection of unit evaporimeter, condenser series connection.
Background technology
Water source heat pump technology is to utilize the solar energy that absorbs in epigeosphere water source such as underground water, river, ocean and the lake and geothermal energy and the low temperature Lowlevel thermal energy resource that forms, and employing heat pump principle, by a spot of high-order electric energy input, realize a kind of technology that Lowlevel thermal energy shifts to high level heat.
Because the water source heat pump system energy-saving and environmental protection more and more are subjected to the approval of various circles of society, country is just going into overdrive to promote its application.This system is widely used in all kinds of buildings such as dwelling house, market, hotel, hotel, school, hospital at present.
In the domestic existing water source heat pump system, during many unit combined heats, all adopt the evaporimeter and the condenser parallel form of each unit.The evaporimeter that is every unit is got a part of low-temperature heat source water respectively, discharges after extracting its heat; The condenser of unit extracts a part of heat supply backwater respectively, after release heat wherein the hot water of preparation isothermal by circulating pump, pipeline homenergic delivery system to space heating.Such system, when big temperature difference confession/backheat water was adopted in heat supply, the efficient of every water source heat pump units all can reduce, and causes system not energy-conservation.
Summary of the invention
When the present invention had overcome water resource heat pump parallel connection heat supply use, if the big flow of confession/backwater temperature difference is little, then the unit operating efficiency reduced to same load, and the problem that operating cost is high is wasted in equipment investment when big as if confession/backwater temperature difference low discharge.
The technical solution used in the present invention is that system and device is made up of many water source heat pump units, low-temperature heat source water, various pipeline, various water pump, circulation water for heating, energy delivery system etc.In many water source heat pump units combining heating systems, the evaporimeter parallel connection of each unit obtains the low-temperature heat source water of uniform temp, extracts wherein and discharges behind the heat; The condenser series connection of per two water source heat pump units, after the low-temperature heat supply backwater entered the condenser of first unit, temperature raise a part of, entered into the condenser of second unit afterwards again, make its temperature continue to raise, pass through circulating pump, pipeline and energy delivery system then to space heating.
The invention has the beneficial effects as follows: the evaporimeter parallel connection of water source heat pump units, condenser are divided into two-stage series connection and use use in parallel with water resource heat pump relatively, the Inlet and outlet water temperature difference of each condenser diminishes, it is big that the circulation water for heating temperature difference of whole system becomes, therefore this system not only makes the efficient of each unit improve, and circulation water for heating is realized the big temperature difference, low discharge operation, the investment and the operating cost of equipment such as reduction water circulating pump, heat supply pipeline.
