Artificial heating and cooling technology (refrigeration and heating) has become an indispensable human civilization an important part of the world since the advent of the first refrigerator has more than 100 years of history, the development of refrigeration technology to promote the development of human civilization, refrigeration With the heating technology to create a more comfortable environment for human life, the application of refrigeration and heating technology has become an indispensable important condition for the development of civilized society today.

Refrigeration and heating (heat pump) is the process and measure of artificially cooling or warming, that is, using a certain device system to artificially quickly (inherent or existing) heat in a space (or something) (Or another part), the temperature (or object) in the space (or object) where the heat is absorbed is decreased (relative), and the temperature in the space (or substance) where more heat is obtained is released.

For a long time, due to various reasons and traditional scientific research mode, the development and application of refrigeration and heating technology have not yet reached the desired level of development, especially large air-conditioning units (refrigeration units) can only be used for cooling and cooling, only part of the power Smaller air-cooled air-conditioning with dual temperature (heat pump) function, but the heating effect is poor, especially in winter to heating heating worse, most of the need for additional electric heating to supplement heating; in recent years the development The so-called water source heat pump and ground source heat pump air conditioners, there are two different configuration modes, one is the larger type of heating and cooling units using a simple external conversion process, so that the traditional chiller (chiller) in the condenser and The generated hot water and evaporator low temperature cold water, respectively, through the conversion process conversion valve output; the other is a small unit, the use of four-way valve switching role in the heat pump unit to achieve the conversion for cooling or The purpose of heating, it is difficult to achieve the ideal multi-purpose dual-temperature effect and energy saving effect.

Up to now, the large air-cooled heat pump air-conditioners have not realized the true all-heat pump air-conditioners so far, and the heat pump units have poor heating effect. Most of them require the direct use of electric-assisted heating and heating heating networks and are difficult to realize timely Frost, especially large-scale heat pump air conditioning unit is more difficult to achieve full heat pump direct heating heating, both some can provide a heating source of heating, but most also add a larger load electric heating, electric heating energy consumption, cost high. Re-condensation of high-temperature multi-function heat pump, take full advantage of the general principles of artificial refrigeration and the use of a variety of artificial refrigeration system of different effects of the process so that the refrigeration (heat pump) unit to achieve high temperature heating and multi-purpose heating conditions Operation, it can realize the function of automatic control conversion, which can make the state of evaporation and condensation (cooling and heating) realize the uninterrupted heating and multi-function heating, which can be used in both cooling and cooling, heating heating and providing domestic hot water.

As we all know, heat pump device is a relatively large input and output energy conversion device, the traditional cooling (heat pump) device can reach more than 1: 2,8 energy efficiency, the rational use of new technology to deploy the development of refrigeration (heat pump) Can reach 1: 5 above, which is the current energy-efficient heating and cooling (or electric) all devices can not be achieved and the energy efficiency, and heat pump device has the advantages of simple structure, stable performance, easy operation, safe and reliable, using heat pump device for all types The building is equipped with cooling and heating for heating, low investment, low cost, no pollution and good management. It is a centralized cooling (warming) device that is ideal for low-cost, high-efficiency and risk-free operation. It also changes the urban landscape of a modern civilization, Creating a more comfortable environment for human life is an indispensable condition. Re-condensation of high-temperature multi-function heat pump heating and cooling technology is a further breakthrough in the development of artificial refrigeration technology breakthroughs for the heat pump air-conditioning and the development of a wide range of popular applications have a good role in promoting, but also to deter depletion of human one-time The transition to energy plays a major role, while avoiding the severe pollution caused by the increased heating of coal-fired boilers, which is an important part of ensuring the planning goal of 65% of building energy efficiency;

High-temperature multi-function heat pump new technologies and new products developed successfully and vigorously promote the use of various low-temperature heat resources can make full use of heat pump technology through the conversion directly to replace the traditional coal-fired (oil) boiler to provide heat for the building is to solve the building Which is a new way to centralize heating and heating; completely avoids the emission and generation of a large amount of dust and noxious gases in the heating process, and achieves the dual effects of energy conservation and emission reduction and effectively protecting the urban atmospheric environment. The new product includes a number of original innovations Technology (such as high-temperature under-voltage artificial heating, secondary condensing heat pump cooling, external dual-temperature conversion, etc.), the comprehensive utilization of a number of patented new technologies, truly a multi-purpose machine, heating heating in winter, summer cooling , While providing hot water for life, but also in the cooling and cooling can be used to prepare high temperature hot water hot water without increasing energy consumption and cost, without any auxiliary heating, to achieve a multi-purpose, without affecting each other, is a real sense The whole artificial heating, refrigeration equipment.

High-temperature multi-functional heat pump is widely used in the efficient recovery and conversion of geothermal resources can increase the conversion rate of geothermal resources, increase the area for heating heating, heating heating network to expand the scope of use, reduce waste of resources, saving both heat Resources, but also reduce the waste of water resources, while avoiding the thermal pollution of the environment. At present, with the promotion and application of heat pump technology, high-temperature multi-function heat pump technology and new products have drawn more and more attention both at home and abroad. The development and application prospects of new technologies and new products and the market economic benefits they generate Social benefits have been initially highlighted, with the essence of innovative technology, large-scale high-temperature multi-function heat pump heating and cooling equipment, new products, will rapidly develop into a good market prospects. It is believed that new technologies and new products of high-temperature multifunctional heat pump will surely be rapidly and extensively developed, popularized and applied as energy demand and supply become more and more tense and environmental problems emerge more prominently.

Energy conservation is emission reduction, energy conservation is environmental protection, and energy conservation is efficiency. The wave of innovation and development with higher energy efficiency and emission reduction targets has risen rapidly across the country. The use of ground-source heat pumps, water-source heat pumps, and other heating, heating and cooling air-conditioners have become the preferential choice for building energy efficiency. Various ministries and commissions of the State Council and all over the country have introduced Preferential policies and subsidies, vigorously support and promote energy-saving heat pump heating technology, and the state have invested a lot of gratuitous funding, the use of strong measures to promote new energy-saving building technologies and renewable energy applications.

Energy is the common resource and material foundation that human society relies on. It is an important national strategic material, especially electricity, and should not become the private property of any unit or individual. Electric heating is one of the oldest and most traditional methods of low-efficiency electricity. It is an irresponsible waste to make extensive use of electric heating for heating.

Electricity is a clean and convenient source of energy, but more should be saved. In some places, due to its abundant electricity and convenience of application, it is indiscriminate (large-scale public buildings are heated by electric boilers). Under the political situation in which the state strongly advocates and vigorously promotes energy conservation and emission reduction, large-scale public buildings use a large amount of electricity Heating heating, its adverse effects can directly hinder the energy-saving emission reduction targets and basic national policy implementation. To achieve "65% energy saving residential buildings, public buildings 50% energy saving" is the country has set the design standards and requirements. To achieve energy conservation, we must first curb waste, direct heating with electric heating, especially in large public buildings using electric heating for heating, which is a waste of electricity, but also a waste of money. Energy conservation has become the common historical responsibility and mission of the entire party and the entire people. It should not save energy and should not be seen as a rule of free administration in our own region. If the 50,000 square meters of large public buildings with electric heating, the consumption of electricity is at least 3-4 times the power consumption of ground source heat pump or water source heat pump heating and cooling system; the same power consumption, ground source heat pump heating and cooling, year-on-year savings More than 70% of electricity; 50,000 square meters of buildings to use electric heating heating power consumption, if the use of ground source heat pump or water source heat pump can solve 15-20 million square meters of heating, therefore, the state will be included in the ground source heat pump " "Eleventh Five-Year" building energy-saving major support technology "one. Heat pump is a mature and high energy-saving new technologies and new products, heat pump heating and cooling system is to reflect the efficient use of electricity the best way, but also the sustainable development of human society an indispensable alternative to new energy sources, to achieve energy-saving building can not be separated from the ground Heat pump, actively promote and apply new heat pump technology, both the real economic benefits, more long-term social benefits, but also has far-reaching historical significance.
