Using Sewage Source Heat Pump Unit Can Save Your Money Sewage source heat pump is one of the most promising heat pump technologies in the world.It is estimated that by 2020, the new residential heating demand area in seven major provinces and cities in north China will exceed 400 million square meters.At present, the area of central heating (non-clean energy) in north China is 5.13 billion square meters, and 100 million square meters of residential buildings will be transformed by clean energy every year. By 2020, there will be 500 million square meters of new construction and renovation, of which about 100 million square meters are eligible for sewage source heat pumps. How Sewage Source Heat Pump Unit Supply Heating? The heating method is the traditional heat pump form, namely sewage source heat pump heating. Sewage water heat pump heating form and the traditional municipal central heating what is different? Sewage-source heat pump heating is not directly heated the water, just take the sewage 3 ℃ to 5 ℃, as heat transfer heat pump units, through the heat pump units energy conversion, will soften the tap water after heating up to 50 ℃ or so, through the heating pipeline to residents of floor heating pipes. Therefore, the hot water that enters residents' homes is the tap water which is being softened and heated. The urban sewage discharged into the underground pipe network has its own temperature. Sewage in winter to keep constant temperature for 13 ℃ - 18 ℃, it is an ideal heat source for heat pump system. Is the introduction of sewage into a special tubular heat exchanger, sewage temperature will be transferred to the clean water, at the same time sewage will be discharged back to the main channel, the next heat pump unit is the use of refrigerant liquid-gas-liquid circulation changes of the heat release and heat absorption principle, then provide heating to the building. Specifically, in the heat exchange process, except the temperature of water changes, neither water resources consumption, nor water quality deterioration. Saving 75% Operating Cost Extracting heat from sewage not only reduces pollution, but also saves energy.Sewage source heat pump heating only requires a little energy consumption, saving coal, fuel oil, gas and other boiler room system, no combustion process, to avoid smoke pollution to the air. With the sewage source heat pump system, each use of a ton of sewage heat, equivalent to the heat generated by burning 1 kg of standard coal. We make a calculation, to heat 1 tons of water from 15 ℃ to 45 ℃ heating need 30000 calories, if by coal-fired heating need 6.9 kg of standard coal, using natural gas needs 4.2㎥into standard coal (5 kg), direct electricity need 35 kw, h into standard coal (about 12.3 kg), and the sewage-source heat pump only consumes 8.7 kw, h into standard coal (about 3 kg).Sewage source heat pumps are three-quarters cheaper than direct heating w...

Heat pump drying technology and traditional drying technology ,which has more advantages? At present, agriculture, food, chemical industry, ceramics, medicine, mineral processing, pulp and paper, wood processing and other industries, all the production process almost all use drying, drying material quality depends on whether a good control of constant temperature. Heat pump drying technology is a mild, close to natural drying method, more suitable for most agricultural products, medicinal materials and other heat-sensitive materials drying. The principle of heat pump dryer is the use of reverse carnot principle of gas compressor pressurized, become (temperature up to 100 ℃), high temperature and high pressure gas entering the indoor side of heat exchanger (condenser), refrigerant condensing liquid heat release of the high-temperature heating drying room air. The materials in the drying room will vaporize and evaporate the moisture in the materials in the form of hot air, and the evaporated water vapor will be discharged by the dehumidification system to achieve the purpose of drying the materials. The heat pump dryer only needs to consume the electrical energy which the compressor USES when the work, may obtain more energy from the air, the energy efficiency ratio is as high as 400%, is more energy saving than other drying methods. 1. characteristics of traditional drying technology For example, at present, most dehydrated vegetables are still produced by the traditional drying method -- oven back to longhuo road heating drying method, which has several problems: 1. The drying temperature is too high. The traditional drying technology, drying temperature is not easy to control, the general drying temperature is about 75-90 ℃, and dehydrated vegetables drying process requirement drying temperature shall not exceed 65 ℃. 2. Excessive drying time. Traditional drying technology, each processing of 1 ton of vegetables need at least more than 24h, sometimes due to poor drying effect to rework, it takes longer. 3. Large energy consumption. Traditional drying technology, thermal efficiency is low, about 30%-60%, in the drying process, drying evaporation water heat accounts for about 36%, waste gas loss accounts for about 58%, dry material heat and dryer heat loss accounts for 2% and 2%, thermal efficiency is only 40%. 2. the characteristics of heat pump drying technology 1. Low drying temperature. Heat pump drying technology of the production technology about 38-52 ℃ lower than the conventional drying technology, the heat pump drying technology of the heating temperature at about 37 ℃. 2. Short drying time. Heat pump drying dehydrated vegetable production process, the need for the time does not exceed about 8h, generally from preheating to product 4h can be completed. 3. Good drying quality. Heat pump drying process produced vegetables, product color is better, the inherent quality is stable. 4. Low energy consumption. Due to the heat pump drying process...

Since air energy heat pump began to enter the clean energy market, it has been favored by users due to its features of energy saving, high efficiency, safety and environmental protection.It is widely used in schools, hospitals, hotels and other fields, especially in the bath place. Taking a foot bath in shenyang as example, coal-fired boilers were used as heating equipment before. Later, due to poor performance and high cost, the operators of the bath chose to dismantle the boilers and use the air energy heat pump system as the new generation of hot water supply equipment. There are several reasons for the choice of air energy heat pump as water supply equipment in the bath center: First, to a large extent ,this equipment is very safe to avoid all kinds of explosions, leakage of electricity and other accidents, so that guests can be safe to wash and enjoy. Second, the air can heat pump is through the absorption of free energy in the air to heat but not use natural gas. The whole process will not cause any pollution gas or substances, which is very helpful for environmental protection.Although the air energy heat pump will also rely on electric energy to drive, but not directly use electricity to produce heat energy, so there is no electric heating element in the water tank, effectively put an end to the occurrence of electric shock accident. Third, the air energy heat pump is green and environmentally-friendly with the national policy of coal to electricity, Fourth, energy-saving can also be a major highlight of the heat pump.Compared with the traditional heating equipment, its energy efficiency is high, the energy saving effect is obvious, there are statistics, in one year using air heat pump heating can save tens of thousands of costs. Air energy heat pump products are not only suitable for places such as bath centers, but also for places with hot water and heating needs. It is believed that with the vigorous implementation of national policies, air energy as a clean energy will win high recognition in the market.

The chilled water change of industrial refrigeration system Production enterprises often need chilled water for cooling in the production process. Due to the influence of production process and market output and other factors, the demand for chilled water is generally very large. In this case, it is very important to design a set of targeted chilled water circulation system. The conventional refrigerated water circulation system is sent to the production water point after being refrigerated by the chiller, and then returned to the chiller to complete the system closed cycle. However, when the water consumption of the system changes greatly, this system will cause the chiller to fail to operate normally. With years of experience in industrial project services, we have designed a solution to address the changing demand for chilled water In the double circulation system, a water storage refrigerated water tank is configured. The water tank is divided into high and low temperature zone, and the system is divided into outer circulation system and inner circulation system. The external circulation system mainly consists of water point, process chilled water delivery pump and freezing water tank. The process delivery pump pumps water from the low temperature zone of the freezing water tank to the water point, and then returns to the high temperature zone of the water tank after cooling. The process transfer pump adopts constant pressure frequency conversion control, automatically adjust the frequency conversion, the operation is more safe and energy saving. The internal circulation system mainly includes a freezing water tank, a freezing pump and a water chiller. The water pumped by the freezing pump from the high temperature zone of the water tank is cooled by the chiller and then returned to the low temperature zone of the water storage tank. With this set of chiller, the water flow into the chiller is not greatly affected by the change of chilled water volume in production, and the water tank has a certain cold storage function, which effectively solves the problem of frequent start up of the chiller and abnormal operation of the chiller. System not only can run safe, reliable, and energy saving effect is very good also, circulating pump from the tank high pumping water to the water chiller refrigeration, after the completion of the transfer to the water storage tank low temperature zone, so the chiller efficiency increase 15%, pump adopts frequency conversion control technology, to better meet the production water consumption change, but also more efficient water pump power consumption.
