Double-compressor air energy heat pump heat supply and heating system

Abstract

A dual compressor air heat pump heat supply and heating supply system comprising a machinery section, a heat supply section, a heating supply section, and an intelligent control section. The machinery section comprises an air heat pump heating section, an electric heating section, a water pipe piece section, and a control circuit section. The control circuit section is for use in controlling the air heat pump heating section to use different compressor combinations on the basis of a detected inflow water temperature and of the ambient temperature. When an outflow water temperature after the compressors are activated is detected to have reached a set temperature, the electric heating section is controlled to not output. When the set temperature is detected to be unattainable, an electric heating power that the electric heating section requires is controlled on the basis of the difference between the detected inflow / outflow water temperatures and of a flow detected by the water pipe piece section. When the air heat pump heating section and the electric heating section are both outputting at full power while the outflow water temperature has yet to reach the set temperature, the water pipe piece section is controlled to regulate water flow via a water flow regulator valve to allow for a constant outflow water temperature.

[0002] The traditional dual-compressor air energy heat pump heating system generally consists of three parts, one is the host part, the other is the water tank part, and the third is the heating system part; for household water tanks, 1. The capacity is generally 150-320L, The volume of the water tank is huge, and it needs to occupy a large part of the building area during installation. Even if some water tanks are installed outside the wall with brackets, due to the weight of the water tank itself, this kind of installation method is quite dangerous; 2. The inner tank of the water tank itself uses Whether it is a stainless steel liner or an enamel liner, water leakage from the water tank is unavoidable due to defects in the manufacturing process; 3. The heat exchanger inside the water tank generally uses copper or stainless steel tubes. In areas with poor water quality, The heat exchange tube will be corroded and perforated, resulting in refrigerant leakage. Once a leak occurs, it will be fatal to the unit; 4. The main unit and the water tank need to be connected by a connecting pipe, so it is difficult to avoid artificial leakage of refrigerant during installation Phenomenon; 5. Due to the characteristics of the water storage heat pump, the water temperature needs to be raised to a higher temperature, and it takes a long time, which cannot meet the immediate water demand, and in the later stage of water use, the water temperature fluctuates greatly, which affects the comfort of use ;In addition, the condensing temperature determines the energy consumption of the unit. The traditional unit with a water tank operates at a high condensing temperature and high condensing pressure for a long time, which will be a great test for the life of the compressor; 6. The water storage type Water tanks generally need to mix water when using water, which will cause several problems. 1) The hot water usage rate in the water tank is not high; 2) During the heat preservation process of the water tank, the water temperature will inevitably drop, which will increase energy consumption; 3) When the user installs the water valve at home, it is necessary to install the water mixing valve, which increases the cost of materials

7. When the general heating system uses the heat in the water tank, it is necessary to install a heat exchange coil inside the water tank to form a closed circuit with the floor heating coil or the radiator and the circulating water pump, which increases the difficulty of the production process of the water tank and occupies Water tank volume; 8. The traditional heating system does not have intelligent control, and it cannot perform various remote monitoring on the heating system, which cannot meet the more humanized needs of modern people: 1) For example, users need to start heating in advance or at regular intervals, But when there is no one at home, it cannot be realized; 2) The user forgets to turn off the heating or heating water when he is outside for a long time, and the heating or heating water cannot be turned off remotely; 3) Some failures occur in the traditional heating and heating system , requires on-site analysis and exclusion, especially in weak or remote areas after-sales outlets, the timeliness of after-sales service and user satisfaction are greatly reduced
