For convenience of description, whole system is divided into three subsystems, is respectively well head winterization system, worker's bath system and the wide building heating of worker, refrigeration system.Described well head winterization system comprises the antifreeze water source heat pump units 5 of well head, secondary water-circulating pump I8, well head de-icer 9, the new blower fan group 10 of well head; Worker's bath system comprises worker's bathing water source heat pump units 6, secondary water-circulating pump II11, plate type heat exchanger II12, bathing water heat cycles pump 13 and bath hot water case 14; The heating of the wide building of worker, refrigeration system comprise worker extensively heat, freeze water source heat pump units 7, secondary water-circulating pump III15, water collecting and diversifying device 16 and the wide building air-conditioning device 17 of worker.
Embodiment 1: well head is antifreeze, worker's bathing, the wide building heating of worker, three systems of refrigeration are independent separately, and wherein respectively there is 50% unit spare capacity in antifreeze, worker's bathing two systems of well head; The wide building heating of worker, refrigeration system do not have standby unit, but can provide standby for the wide building heating of worker, refrigeration system with the spare capacity of well head winterization system and worker's bath system.Select for use a cover water treatment and water charging system to be respectively three system water supplements.
According to this thinking, the well head winterization system is selected three SRSW-250-2 types (the standard condition heating capacity is 947.5kW) water source heat pump units for use, and dual-purpose one is equipped with; Three SRSW-ZGW-100M-1 types (the standard condition heating capacity is 327.4kW) water source heat pump units is selected in worker's bathing for use, and dual-purpose one is equipped with; Two SRSW-ZGW-400M-4 types (the standard condition heating capacity is 1309.5kW) water source heat pump units is selected in the wide heating of worker for use.Total heating capacity is 6443.7kW.
In the present embodiment, well head winterization system and worker's bath system respectively have 50% standby surplus, and the wide building heating of worker, refrigeration system are standby for the independent operating system does not have, and system reliability is the highest; But investment cost height, operating cost are slightly high.
Embodiment 2: well head winterization system and worker's bath system respectively are the independent operating system, but a common standby water source heat pump units, worker's bath system spare capacity is 100%, well head winterization system spare capacity is 40%; The wide building heating of worker, refrigeration system are autonomous system, do not have standby unit.
According to this thinking, worker's bath system configuration SRSW-200-2 type (the standard condition heating capacity is 769.5kW) water source heat pump units; Well head winterization system configuration two SRSW-250-2 types (the standard condition heating capacity is 947.5kW) water source heat pump units; When worker's bath system or well head winterization system heat pump break down, be its supplemental heat source by standby unit, this kind standby mode uses for emergent; The wide building heating of worker, refrigeration system are selected two SRSW-ZGW-400M-4 types (the standard condition heating capacity is 1309.5kW) water source heat pump units for use, wherein supply apartment and ore deposit office building air conditioner refrigerating a summer, and standby each other with worker's bath system.Total heating capacity is 6053kW.
In the present embodiment, the standby unit of the shared cover of well head winterization system and worker's bath system, the well head winterization system has 40% standby surplus, and worker's bath system has 100% standby surplus, the wide building heating of worker, refrigeration system are standby for the independent operating system does not have, and system reliability is higher; But investment cost height, operating cost are slightly high.
Embodiment 3: the well head winterization system adopts two water source heat pump units, and worker's bath system adopts a full recuperation of heat water source source pump, and the wide building heating of worker, refrigeration system adopt two big one little three water source heat pump units.Wherein the wide building heating of worker, the little unit of refrigeration system form unidirectional standby with well head winterization system and worker's bath system respectively, be well head winterization system or worker's bath system when in a single day breaking down, the little source pump of the wide building heating of worker, refrigeration system by backup line to well head winterization system or the heat supply of worker's bath system.This kind standby mode is the emergency power mode, and pending fault should recover the former method of operation after getting rid of immediately.
When summer, worker's bath system provides free low-temperature receiver for ore deposit office building and apartment air conditioner refrigerating when worker's bath hot water is provided.Summer when ore deposit office building and apartment air conditioner refrigerating like this, only open the requirement that the wide building heating of worker, the little unit of refrigeration system can satisfy air conditioner refrigerating, the wide building heating of worker, the big unit of refrigeration system are standby unit.This system's design can be saved 50% operating cost when summer air-conditioning freezes.
According to this thinking, the well head winterization system is selected two SRSW-250-2 types (the standard condition heating capacity is 947.5kW) water source heat pump units for use; Worker's bath system is selected a SRSW-QH200-2 type (the standard condition heating capacity is 769.5Kw, and the recovery heat is 719.2Kw) water source heat pump units for use; The wide building heating of worker, refrigeration system are selected two SRSW-ZGW-300M-2 types (the standard condition heating capacity is 950.9kW) and a SRSW-ZGW-200M-2 type (the standard condition heating capacity is 654.8kW) water source heat pump units for use, can satisfy the wide building heating requirement of worker fully.The SRSW-ZGW-200M-2 water source heat pump units of the wide building heating of worker, refrigeration system and worker's bath system can form 100% standby in addition, with the well head winterization system form 40% standby, standby temporarily when breaking down to guarantee worker's bath system and well head winterization system.
During summer, the full recuperation of heat unit of SRSW-QH200M-2 provides worker's bath hot water simultaneously, freely provides low-temperature receiver for ore deposit office building and apartment.So only open little unit of SRSW-ZGW-200M-2, can satisfy ore deposit office building and the requirement of apartment air conditioner refrigerating.This system's design can be saved 50% operating cost when summer air-conditioning freezes.
In the present embodiment, the wide building heating of worker, refrigerant system design two big one little three water source heat pump units, two water source heat pump units of well head winterization system design, water source heat pump units of worker's bath system design.Under normal circumstances, three systems are independent operating all, and only when well head winterization system or worker's bath system broke down, the wide building heating of worker, the little source pump of refrigeration system were done standby for well head winterization system or worker's bath system temporarily, after the system that treats repairs, recover the wide building heating function of worker.Little unit has 40% standby surplus for the well head winterization system, and worker's bath system has 100% standby surplus.The reliability of the wide building heating of worker, refrigeration system is than scheme one and scheme two differences, and heat in the mining area, the refrigeration requirement but also can satisfy fully, and can stable operation.But investment cost is minimum, and operating cost is minimum.
In sum, the present invention integrates advanced and heats, Refrigeration Technique and Intelligent automatic-control technology, replaces coal-burning boiler system fully, has really realized energy-saving and emission-reduction, has greatly improved environment of mining area, and economic benefit and social benefit are obvious.
