Abstract

Antiscale and nullah heat water source heat pump unit, which involves a water source heat pump unit. The purpose of this invention is to solve the existing water source heat pump unit in the using of municipal sewage or surface water such unclean water, the large amount of investment, low operation efficiency, energy consumption, as well as the plug and dirt difficult issues. The invention of a number of tube (3) parallel connected to the base flow and the base flow (4) maintaining a gap, a number of tube (3) ends with the two refrigerant even ( 5) connectivity. All of the water in the channel or heat exchanger tank are of water flow, water tank wall coverage on the tube heat exchanger flow velocities greater flow again from top to bottom, the impurities and dirt-China and carrying a role; according to channel flows, heat transfer wall velocity, Renault several criteria, therefore sewage or surface water side of the convective heat transfer coefficient, higher efficiency unit; not alone prevent anti-scaling technology or equipment, water pumps small power consumption, the system reduces power consumption.

Description

technical field

[0001] The invention relates to a water source heat pump unit. Background technique

[0002] Unclean water sources such as urban sewage or surface water (rivers, lakes, and sea water) are a huge low-temperature, low-level thermal energy resource. Using water source heat pump technology to extract heat or cold energy from it is used for building heating and air conditioning, which has important energy-saving and environmental protection value, can alleviate the energy consumption and environmental pollution of HVAC, and the main equipment is the water source heat pump unit.

[0003] Existing water source heat pump units are composed of compressors, condensers, dry filters, expansion valves and evaporators connected by pipelines. The evaporators do not have the ability to prevent blockage and scale, and are suitable for clean water sources. Such as groundwater.

[0004] However, non-clean water sources such as urban sewage or surface water (rivers, lakes and ...
