Description

  • Technical area
  • The present invention relates to the field of dual compressor heat pump heating and air supply heat supply, and more particularly to an instant-on-demand dual compressor heat pump and heat supply system with intelligent control.
  • Description of the Related Art
  • A traditional dual compressor heat pump and heat supply system using air for use with existing air power water heaters generally consists of three parts: the main engine, the water tank and the heating system. Firstly, for a domestic water tank, large water tanks with a general capacity of 150 to 320 liters occupy a lot of space in a building during installation, and even if they are mounted on a rack outside the wall, the installation process is due to the tank's own weight and therein water risky. Secondly, as regards the material and technique of the tank lining, this stainless steel or enamel can not be avoided due to defects in the production technology spills. Third, the heat exchanger in the tank is generally made of copper or stainless steel tubing which can corrode and become leaky in regions of poorer water quality. This leads to leakage of refrigerant, which would be fatal for the device. Fourth, the main engine and the water tank need to be connected to each other with a connecting pipe, so that man-made refrigerant spills during installation are difficult to avoid. Fifth, due to the characteristics of water storage type heat pumps, a long time is required for warming the water to a higher temperature, whereby an acute demand for water can not be satisfied. In addition, the water temperature fluctuates later, which may affect the comfort of the water user. In addition, since the height of the condensation temperature determines the energy consumption of the device, the long-term operation at high condensation temperature and high pressure of a traditional system with water tank can be a heavy burden on the service life of the compressor. Sixth, in the case of a water tank type water tank, it is generally necessary to mix the water for use, which may cause several problems: 1) the utilization rate of the warm water in the water tank is low; 2) while keeping warm, the water temperature in the water tank inevitably drops, which can increase the energy consumption; 3) If a water valve is installed in the user's house, it is essential to also install a water mixing valve, which can increase the material costs. Seventh, in general, in case that the heat for the heating system comes from the water tank, a heat exchange coil must be installed to form a closed circuit with a bottom heating coil or a radiator and a water circulation pump, which increases the technical difficulty of tank production and space in the water tank occupies. Eighth, since traditional heating and heat supply systems do not have an intelligent controller, remote monitoring operations can not be performed, so that the high demands of modern people can not be met. 1) For example, the user has to start the heating system in advance or at a certain time when he is not at home - an impossibility; 2) if the user is away from home for a long time and forgets to shut off the water to be heated, the heating system can not be remotely switched off; 3) In case of errors, traditional heating and heating systems require an on-the-spot analysis for troubleshooting, but especially in regions with poor after-sales service or in remote regions, customer service times are not consistent with user expectations and affect their satisfaction.
