Description
Technical field
The present invention relates to air-conditioning ground heating technical field, relating in particular to one can the central controlled sky of locellus timesharingAdjust ground heating system.
Background technology
In the epoch of nowadays advocating environmental protection and energy saving, utilize high energy efficiency and the ring of heat pump principle Technology design exploitationThe hot-water heating system of protecting more and more receives people's concern. Air source heat pump system is by utilizing a small amount of electricityCan, thus by airborne transfer of heat the equipment to hot water preparing in water, it is to utilize contrary Carnot cyclePrinciple, by the work of compressor, realizes the transfer of low temperature heat energy to high temperature heat. This mode that heatsSave greatly the energy.
Along with the fast development of heat pump industry, heat pump is also no longer confined to Teat pump boiler, current, with heatThe combination of pump type air-conditioner, as three-in-one in air source heat pump (domestic hot-water, air-conditioning, heating), especiallyThat the product of heating system end starts to tromp to market in combination. Based on the air-conditioning of air source heat pump systemThat floor heating has is energy-conservation, safety and the easy many merits such as control. The three-in-one unit of air source heat pump, rootAccording to the needs of the different occasions of Various Seasonal, can realize single water heating, single refrigeration, single (two) heating,Refrigeration heat production simultaneously water, heating heat production simultaneously water, its scope of application is extremely extensive.
For reducing energy consumption, meet the theme of " energy-conserving and environment-protective " advocated now, existing air source heat pumpIn three-in-one unit, in the situation that Pipeline Water flow is stable, air source heat pump is for stopping or in dormancy shapeState. In the three-in-one unit of existing air source heat pump, mostly be central heating, can not carry out the control of timesharing locellusSystem. In addition, because the pipeline of the three-in-one unit hollow of existing air source heat pump air supply heat pump is direct and emptyTune floor heating pipeline is communicated with, and in practical application, due to each indoor independent control of needs, therefore can drawPlay discharge in pipeline unstable, change frequent, and then directly cause air source heat pump frequent starting orStop, affecting the service life of system.
Therefore, a locellus time-sharing system packaging, be by the control of source pump and end (fan coil,Floor heating water collecting and diversifying device, radiator etc.) control combine well, ensure that user each room temperature dividesChamber timesharing control, whole system is stable, energy-conservation, extends system service life.
Summary of the invention
For the deficiencies in the prior art, the invention provides one can the central controlled air-conditioning of locellus timesharing groundHeating system.
