Problems solved by technology
[0003] In the existing water loop heat pump system, the cold source (such as cooling tower) in summer and the heat source (such as boiler) in winter are both single cold and heat sources. Moreover, the cold source or heat source is provided by fuel combustion, which consumes a lot of energy and pollutes the environment. Difficult to achieve more economical and environmentally friendly system operation

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] The multi-cold, heat source water loop heat pump system of the present invention is shown in Fig. 1, which includes a heat exchanger 1, multiple water-cooled heat pump units, a balance waterway 5, a cold / heat source heat exchanger 6 and a cold / heat source heat exchanger 7. Multiple water-cooled heat pump units are connected through the balance waterway 5, and the two ends of the balance waterway 5 are respectively connected to the water inlet and water outlet of the heat exchange tube of the heat exchanger 1 through the balance waterway water pump 4, and the water inlet and water outlet of the heat exchanger 1 The water pump is respectively connected to the inlet and outlet of at least one set of cold / heat source heat exchanger heat exchange tubes, and the cold / heat source heat exchanger exchanges heat with the cold / heat source. The co...

The invention discloses a water-water heat pump system with multiple cool-hot resources with the purpose that multiple low grade cool-hot resources are provided for water-water heat pump system so as to improve whole efficiency ratio of water-water heat pump system and decrease running cost, comprising water cool-hot pump group and balance water road. Multiple water cool-hot pump units are connected by the balance water road and two ends of the balance water road are connected with inlet and outlet of heat exchanging pipe by water pump of balance water road respectively. The inlet and outlet of heat exchanger is connected with the inlet and outlet of a group of heat exchanging pipe of cool-hot resource heat exchanger by water pump at least. Between the cool-hot heat exchanger and cool-hot resource heat energy is exchanged. The energy source used is one of soil, underground well water, surface water, industrial waste cool and architectural natural cool resource at least. Because of multiple cool-hot resources applied the energy efficiency of water-water heat pump system is improved and cool-hot resource used is low grade and circumstance protection energy so as to decrease cost.
Description
technical field [0001] The present invention relates to a water ring heat pump system, and more specifically relates to a system that adopts various types of cold sources or heat sources to balance the heat or cold released by the water ring heat pump system. Background technique [0002] Water ring heat pumps are widely used in the field of air conditioning, and its principle is to connect many small water-cooled heat pump units with balanced waterways. In summer, the small heat pump unit absorbs the heat of the room and discharges the heat into the balance waterway. When the temperature of the balance waterway is too high, the cooling tower connected to the balance waterway is turned on to cool the water in the balance waterway through the cooling tower; in winter, the small The heat pump unit absorbs the heat in the balance waterway and releases the heat to the room. When the temperature of the balance waterway is too low, the boiler connected to the balance waterway is t...
