First, the unit profile:
Sewage source heat pump system can be heated or can also provide hot water perennial hot water, really a multi-purpose machine. Sewage source heat pump unit is a way of using sewage resources. The source of the sewage source heat pump system absorbs heat from the environment, along with the energy consumed, to the object that needs to be heated to achieve the purpose of heating; likewise, it can also absorb heat from high temperature objects, transfer heat to the environment, the goal of.
It is understood that the use of sewage source heat pump system to achieve cooling or heating the building, making the low heat in the sewage has been fully utilized to reduce the consumption of other types of energy, but also to avoid environmental pollution. At the same time, due to the sewage source heat pump system performance coefficient is large, in the operation of energy-saving effect is significant, the adverse impact on the environment is greatly reduced. In addition, the sewage source heat pump also has a very good economic benefits, more concentrated heating to save operating costs more than 20%, compared with other programs to save energy more than 15%.
Compared with other heat sources, sewage source heat pump system technology is the key and difficult to prevent clogging, anti-pollution and anti-corrosion. In order to solve the problem of corrosion of the heat pump unit, Ruibao Liheeng Technology Co., Ltd. independently developed a special full-flow heat pump unit for sewage, referred to as sewage source heat pump unit.
Sewage source heat pump unit products applied to the direct system, to achieve the sewage (has been anti-machine treatment) direct use, improve the utilization of sewage source heat. Sewage side heat exchanger using navy copper, to solve the sewage on the unit pollution and corrosion problems.
Second, the working principle
Refrigeration principle: the refrigerant in the evaporator heat absorption, the preparation of cold water into the room to use, the refrigerant compressed by the compressor into a high temperature and pressure of superheated steam into the condenser, from the sewage away heat and return to the sewage trunk.
Heating principle: the evaporator into a condenser, the condenser into an evaporator. The refrigerant evaporates in the evaporator to absorb the heat of the sewage, the sewage is returned to the sewage main canal; the refrigerant is compressed into the high temperature and high pressure superheated steam into the condenser, and the circulating water is heated to make hot water.
work process
Sewage from a sewage pump to the engine room, after the intelligent sewage anti-blocking machine filter, into the sewage source heat pump unit; by the heat pump unit temperature (or cooling) after the sewage flow through the intelligent sewage anti-resistance machine and carry contaminants Back to the sewage canal. The source heat pump unit cools (or heats) the end system.
Third, the product features
Dedicated full liquid type sewage source heat pump unit of the sewage side of the heat exchanger, the heat transfer tube for the sewage corrosion corrosion tube. The unit uses six dedicated technologies to improve unit performance.
(1) the use of full-liquid evaporator, effectively improve the sewage source heat pump unit evaporation temperature;
(2) dedicated jet pump in the state without energy, the system to complete the continuous return oil, safe and reliable;
(3) specially designed high-performance condenser, can reduce the sewage source heat pump unit condensation temperature;
(4) the use of two-stage compressor technology (used in high-temperature water source heat pump);
(5) the unique oil separator and flicker-type energy-saving device reasonable configuration;
(6) the use of low-voltage supercharging technology - exclusive first.
Sewage source heat pump unit which, spray evaporator + high efficiency heat transfer tube + low pressure booster technology = increase the evaporation temperature;
Secondary compression technology + increase the evaporation temperature = increase the cooling capacity (Qc);
Unique condenser design + high efficiency heat transfer tubes = lower condensing temperature;
Reduce the condensing temperature + dedicated compressor volume ratio selection = reduce the compressor power consumption (N).
