HC HVAC & R Network Sewage source heat pump technology features and advantages of
Wastewater Source Heat Pump is the main technical principles of operation of heat pump system, will heat or cool water in the amount delivered to the building. Can be divided into three energy transfer process:
The first process: the media unit in Evaporator Need to absorb the heat inside the evaporator, the evaporation temperature of medium 3 , 10 at this time the medium after the water in the evaporator, with medium heat and heat release to the media, media absorb heat evaporation.
Second process: set their own media cycle, evaporation of the gas is Compressor Inhalation and compressed into high temperature, high pressure gas into the condenser, heat to the condenser to achieve the process of transformation, and the condenser is connected with the end of the system.
Third process: unit high temperature and pressure the media into the condenser cooling, heat release and heat exchange with the system water to achieve absorption in the evaporator's heat and the total energy input to output Heating The process water system, water heating system with heat release to the room, to heating purposes. Throughout the process, the unit of energy input-output ratio up to 4.5, that is, Motor Input power is 1kcal, the end of the system are the energy is 4.5kcal. Throughout the course of a small amount of electricity consumed, great use of water energy, so as to achieve Energy Purpose of cooling and heating process is the process of reverse process.

independent research and development of sewage source heat pump system is the key to take the process of how to prevent heat on heat transfer equipment, poor water quality and pollution blocking. Primary sewage debris of a large number of large scale, for example, Shuo Liao Dai, leaves, causing blockage of contaminated equipment and piping, the traditional filter grid means and machinery to dispose of the debris though, but not the actual operation, involving to land, clean up, debris transport and the surrounding Environment Pollution problems, even with the simplest of the water treatment process, the processing cost significantly higher than the heat pump should the water get hot and get cold value, and indeed the city covers an area of water treatment process is also problematic. Undoubtedly, urban sewage source heat pump to bring the extinction of a disaster, it is also delayed the development of the technology problems. Therefore, to solve poor water quality on the heat transfer equipment and pipeline clogging and pollution carried out in the traditional sense of the treatment is not feasible. As the primary characteristics of sewage water, to water heat pump technology, compared with the other two have their own characteristics, but also the key technology of the system.
(1) application process and equipment. Sewage source heat pump water loss control of intelligent machines (referred to as intelligent discourage machine) rotation filter surface itself, at any time are part of the filter in the filtration of the work surface area, particle size is specified over the sewage solids, suspended solids filter surface was retained, so that with the size of suspended solids to the wastewater the following Heat exchanger No blocking heat transfer. The other part of the filter surface area in the hydraulic recoil. In the filter plane rotation within a week, every hole has a filter part-time work in the filter area to exercise filtering, the other part is in the anti-anti-wash rinse zone, to restore the filtering function. After the water through the filter without blocking heat transfer to the heat exchanger, heat exchanger effluent return backwash water loss control unit surface area of the filter to backwash, and would kick away all debris washed off the sewage effluent back side by side pipes. Successfully resolved a large number of urban sewage debris caused by the use of equipment and pipeline blockage problem of pollution. Use of the technology and equipment, can guarantee that urban sewage heat exchanger without plugging in a long run, so that large-scale application of urban sewage as a heat pump source a reality.
(2) water heat exchanger.
Though the addition of sewage in some of the larger debris, but the mini is still a lot of sediment and fibrous dirt there, actually they can not take the sewage treatment process, because the processing fee even higher than the value of the heat extracted twice .
