Water-mixing device for waterhead heat pump units

Abstract

A water mixing device for a water source heat pump unit relates to the water source heat pump central air-condition technical field. The invention comprises a water source heat pump unit and a water mixer connected with a water system inlet of the water source heat pump unit, an immersible pump which is arranged in the water source and extracts the water source and a water mixing pump which is connected with a water system outlet of the water source heat pump unit and extracts the discharged water from the water source heat pump unit. The structure is characterized in that the sectional area of the tank body of the mixer is greater than the main pipe area of the water system. The top of the mixer is vertically provided with a water inlet 1; the side of the mixer is horizontally provided with a water inlet 2. The water inlet 1 and the water outlet 2 are respectively connected with the water outlets of the water mixing pump and the immersible pump. The middle part of the inner chamber of the mixer is provided with a tapered flow equalization plate with micropores; the tapered node of the tapered flow equalization plate is upward vertically. Compared with the prior art, the invention can achieve the proper water mixing temperature, thereby having an energy-saving operation of the unit, prolonging the service life-span of the system and achieving water-saving operation.

Description

technical field [0001] The invention relates to the technical field of water source heat pump central air conditioners, in particular to a water mixing device for water source heat pump units. Background technique [0002] The water source heat pump central air-conditioning system has been widely used in recent years. It can use groundwater, surface water, industrial wastewater, and domestic sewage to prepare air-conditioning circulating water, saving a lot of energy. Due to the many problems of surface water, industrial wastewater and sewage water temperature and water quality, most of the projects put into operation still use groundwater as the main source water of the heat pump central air-conditioning system. [0003] In the past 10 years of practice, groundwater intake and recharge technology has made great progress, and the water source heat pump technology using groundwater as water source water is becoming more and more mature. However, due to the vast territory of ...

Problems solved by technology

Practice has found that in some projects, the temperature of the mixed water is difficult to achieve the design effect. At the same time, there is a big problem in the pressure matching of the water source water pump and the mixed water pump, which makes it difficult for the mixed water to enter the main machine water system, which affects the use of the mixed water device. Affected the further popularization of water source heat pump system technology
