Abstract
The utility model relates to a multi-unit hydraulic balance-type modularized heat pump set applied to the heating ventilation engineering field of air conditioning, which consists of a plurality of independent refrigerant (heating) units which are provided with a water inlet pipelines and a water outlet pipelines. The water inlet and outlet pipelines between each refrigerant (heating) unit are connected by same route hydraulic balance-type and each water pipeline is connected with a condenser 4 and an evaporator 5 of each unit by adopting the form of equal-resistance different-caliber, thus leading the water resistance and flux flowing each unit to be equal and reach the rated refrigerant (heating) amount, so as to ensure the whole module set to run adequately and effectively.
Description
Technical field
The utility model belongs to the HVAC refrigeration technology field, relates to a kind of multiple-unit modular heat pump unit that is applied to industry and civil buildings air-conditioning heating and ventilation project.
Background technology
In present air conditioner refrigerating field, the modular heat pump unit is owing to have higher reliability and more excellent energy saving in running characteristics than traditional separate unit handpiece Water Chilling Units, thereby is widely used in the heating and ventilation project of industry and civil buildings air-conditioning.Known modular heat pump unit is to connect the device that combines by water-system pipeline by a plurality of independent coolings (heating) unit, each independent cooling (heating) unit has on all four structural behaviour, it is (heating) system of independently freezing that they all are made up of routines such as compressor, condenser, throttle expansion valve, evaporimeter refrigeration parts, with the water system in each unit with pipeline couple together just formed module machine always advance water return pipeline, thereby realize the refrigeration and the heat supply purpose of source pump.When unit freezed, water system was chilled water and cooling water water-in and water-out pipeline, and water system then is hot water and heat source water (comprising low potential temperature water sources such as well water, spent hot water) water-in and water-out pipeline when heating.In the prior art; what the connection of water system was adopted between each refrigeration unit in the modular heat pump unit all is that different formula connects; its structure as shown in Figure 1; because the general export of the general import of inlet pipeline (comprising chilled water water inlet pipe 1 and cooling water inlet pipe 1 ') and outlet conduit (comprising chilled water outlet pipe 2 and cooling water outlet pipe 2 ') is provided with end in the device; so that water system advances; the on-way resistance of outlet conduit from unit A1 to unit An is all inequality; thereby cause the difference of each unit flow of inlet water; because water is easy to flow out the formation short circuit from the unit A1 of resistance minimum; each unit inhomogeneous meeting of the turnover water yield causes the part unit not reach designed declared working condition because of the decay of refrigeration (heating) amount; and then influence and reduce the power output of whole module unit, and may cause the disorderly closedown of certain unit.In order to address the above problem, present some producer's employing water inlet, delivery port in each unit of source pump installs control valve 3 additional and comes the purpose of the resistance of each unit of balance with flows such as reaching, but manual adjustment valve both inaccuracy is also inconvenient, if install dedicated water dynamic balance valve additional, can make system cost too high again.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of multiple-unit hydraulic equilibrium formula modular heat pump unit that guarantees the full-amount efficient operation of whole modular system is provided.
The technical solution that adopts is so for achieving the above object: the turnover pipeline between each refrigeration (heating) unit in the source pump is adopted connect with journey hydraulic equilibrium formula, it is identical with flow and reach specified refrigeration (heating) amount to connect the water resistance that makes each unit of flowing through by this reversed return type, thereby the whole module unit that guaranteed to be in operation can reach design conditions.

Fig. 1 is the structural representation of present known multiple-unit modular heat pump unit.
Fig. 2 is the structural representation of a specific embodiment of the utility model.
Fig. 3 is the structural representation of the utility model water-system pipeline.
The specific embodiment
Referring to accompanying drawing, multiple-unit hydraulic equilibrium formula modular heat pump unit described in the utility model has an inlet and outlet pipe 1 by a plurality of, 2 independent cooling (heating) unit A1, A2, ... An forms, water inlet with each unit, outlet system is pressed with journey hydraulic equilibrium arranged in form, promptly by inlet pipeline 1,1 ' and outlet pipeline 2,2 ' makes each unit parallel connection, with inlet channel 1,1 ' general import and outlet conduit 2,2 ' general export heterodoxy is provided with, simultaneously with each unit inlet pipeline 1,1 ' caliber does to successively decrease the reducing setting along water (flow) direction with the unit ordering, with each unit outlet pipeline 2,2 ' caliber does to increase progressively reducing setting (referring to Fig. 3) along water (flow) direction with the unit ordering, every waterpipe such as all adopts to become the mode of caliber and the condenser 4 of each unit at resistance like this, evaporimeter 5 links to each other, make the water resistance of each unit of flowing through identical, can reach specified refrigeration (heating) amount when guaranteeing the source pump operation with flow.No matter how system's water yield changes in the utility model running, all need not each unit is done again the hydraulic equilibrium adjusting of other form, can effectively guarantee the full-amount efficient operation of whole modular system.
Design described in the utility model and example structure both be applicable to multiple-unit water-cooling type modularization handpiece Water Chilling Units, be applicable to that also water outlet is Wind-cooling type multiple-unit modularization hot and cold water (heat pump) unit of cold and hot water supply system, be applicable to also that simultaneously the antifreeze aqueous solution of spent glycol does the hot and cold water unit of medium, as water resource heat pump module unit, soil seedbed and source heat pump module unit etc.
Claims (2)
1, a kind of multiple-unit hydraulic equilibrium formula modular heat pump unit, by a plurality of independent refrigeration units with inlet and outlet pipe (1,1 ', 2,2 ') (A1, A2 ... An forms, it is characterized in that each refrigeration unit (A1, A2 ... the turnover pipeline between the An adopts and connects with journey hydraulic equilibrium formula.
