When being begun the refrigeration performance test by examination wind-cooled cold-water (heat pump) unit; Use side water by examination wind-cooled cold-water (heat pump) unit passes through to use the side water pump; Thermostatic control district chilled water water delivering orifice water intaking from the thermostatic control zone gets into by the test-run a machine group and uses the side water-side heat; Used the water outlet of side water by the test-run a machine group, get back to constant temperature water tank through the heat release district chilled water import in heat release zone.Too high in order to prevent temperature; The handpiece Water Chilling Units water inlet high temperature protection of heat dissipation; The water delivering orifice water intaking in the heat release district in heat release zone transports through cabinet type fan coil water pump, gets into the preliminary consumption that cabinet type fan coil is accomplished heat; Through the water that heat dissipates, get back to water tank via the equilibrium area cooling water inlet in combined balance system zone.Equilibrium area water delivering orifice water intaking in the combined balance system district gets into the dissipation handpiece Water Chilling Units, the problem that too high protection is reported to the police with regard to the handpiece Water Chilling Units temperature that can not dissipate like this.After handpiece Water Chilling Units excess enthalpy heat dissipation, backwater is divided into two-way, and one the tunnel gets back to constant temperature water tank via the equilibrium area chilled water import in combined balance system zone, and one the tunnel gets back to constant temperature water tank via the thermostatic control district chilled water import in thermostatic control zone.Like this, the outside clockwise cyclic process of water tank is accomplished.
When being begun the heat pump performance test by examination wind-cooled cold-water (heat pump) unit; Use side water by examination wind-cooled cold-water (heat pump) unit passes through to use the side water pump; From the thermostatic control district chilled water water intaking in thermostatic control zone, get back to constant temperature water tank through the heat release district chilled water import in heat release zone.The water delivering orifice water intaking in the heat release district in heat release zone transports through cabinet type fan coil water pump, gets into cabinet type fan coil.Usually, the blower fan of cabinet type fan coil does not leave.When the refrigerating capacity of quilt examination wind-cooled cold-water (heat pump) unit is very big, can open the blower fan of cabinet type fan coil.At this moment, the water and air heat exchange that cabinet type fan coil table cooling coil is inside and outside, water can a part absorb heat from air, thereby can reduce the electrically heated injected volume of constant temperature water tank.Then, backwater is got back to water tank via the equilibrium area cooling water inlet in combined balance system zone.In the water intaking of the equilibrium area water delivering orifice in combined balance system district, get into the dissipation handpiece Water Chilling Units, the one tunnel gets back to constant temperature water tank via the equilibrium area chilled water import in combined balance system zone, and one the tunnel gets back to constant temperature water tank via the thermostatic control district chilled water import in thermostatic control zone.Like this, the outside clockwise cyclic process of water tank is accomplished.
Water tank outer loop process, the counter clockwise direction that must bring the difference in height of each regional water level of water tank, this difference in height to promote between inner three zones of water tank circulates.
The heat release district receives by the use side water water outlet of examination wind-cooled cold-water (heat pump) unit, and through water pump this part water is introduced cabinet type fan coil units and carry out heat release; The combined balance system district receives cabinet type fan coil units water outlet; And through water pump this part water is introduced the heat dissipation and carry out the secondary heat release with air-cooled (perhaps water-cooled) handpiece Water Chilling Units (hereinafter to be referred as the dissipation handpiece Water Chilling Units), this zone is also taken back in a part of water outlet of the handpiece Water Chilling Units that dissipates simultaneously; The thermostatic control zone receives another part water outlet of dissipation handpiece Water Chilling Units, and the water inlet condition of being used side water by examination wind-cooled cold-water (heat pump) unit is provided.Above water-flow chart process is accomplished the outside water route cyclic process of constant temperature water tank.
