In the increasingly fierce market competition, the current imitation of simple products and the replication of marketing can no longer adapt to the current competitive situation, which brings new challenges to most air source heat pump enterprises. Why can the direct heating mode of this device become the user\\\\\\\'s choice? Here are the advantages of this mode. 1. Green and environmental protection: new refrigerant working medium can be selected, which fully meets the environmental requirements of the new era; There is no harmful waste gas or slag generated during the heating process, providing users with a comfortable and high-quality living environment 2. Convenience and comfort: provide users with satisfactory domestic hot water 24 hours a day, and users can enjoy the comfort of air energy heat pump unit hot water anytime and anywhere. 3. Direct hot water supply, circulating constant temperature: the tap water enters the unit and comes out with the hot water of the water temperature required by the user. The water temperature is constant and the system is safe. 4. High efficiency and energy conservation: make the energy efficiency more than 4.2, 1/3 of the boiler, save considerable costs for users, and recover the initial investment in the short term. 5. Safe and reliable: The refrigeration working medium is used to heat the water, which completely eliminates the potential safety hazards such as flammability, explosion and electric shock in the common heat source. The advanced intelligent control and humanized water supplement method are used, so that the unit can operate even when the temperature is as high as 40 ℃ and as low as - 10 ℃. 6. The advanced waterway control system is adopted: the inlet and outlet water temperature sensing head and electronic flowmeter are used to control the electric valve on the waterway through the outlet water temperature to regulate the water flow, so as to meet the requirements of independent control of outlet water temperature. In this way, the water temperature can be controlled accurately and adjusted conveniently. Ensure system safety.

How to improve the efficiency of air energy heat pump and extend its service life? You must have such a question. Now let\\\'s follow up with our small staff of Nakstar to understand that the operation performance and service life of the irregular and effective maintenance unit will be greatly improved! 1. When the temperature is lower than 2 ℃, if the unit is stopped or power is cut off, the water in the unit pipeline must be drained in time, the power supply must be cut off, and protective measures must be taken. During re operation, the system shall be comprehensively checked and confirmed before startup. 2. The water filter installed in the unit shall be cleaned regularly according to the local water quality (preferably once a quarter) to ensure that the water quality in the system is clean and the water circulation is smooth, so as to avoid affecting the efficiency of hot water production or accidental damage due to dirty water or filter blockage and reduced water circulation. 3. Check whether the wiring of the electrical system of the unit is firm and whether the electrical components are abnormal. If any, please handle it in time. 4. Regularly check whether the water make-up, liquid level controller and exhaust device of the water system work normally, so as to avoid excessive overflow and reduction of water circulation, which will affect the heat generation of the unit and the reliability of unit operation. 5. Please keep dry operation and good ventilation around the unit. Clean the air side heat exchanger regularly (preferably once a quarter) to maintain good heat exchange effect. Do not stack sundries around the unit to avoid blocking the air inlet and outlet. Keep the unit clean and dry with good ventilation. 6. Frequently check the working condition of each component of the unit, check whether there is oil stain at the unit pipe joints and air charging valves, and ensure that there is no leakage in the refrigeration of the unit. Pay attention to check whether the water pump and waterway valve work normally, and whether there is leakage in the water pipeline and water pipe joints. 7. The scale of the water tank shall be removed after being used for a period of time (depending on the local water quality).

When it is used in the north, it is inevitable that the equipment will be frosted due to the influence of low temperature weather. I will discuss the harm of equipment frosting and the method to solve the problem. Frosting hazard of air source heat pump: when the air source heat pump unit operates in winter, when the surface temperature of the heat exchanger outside the room is lower than the dew point temperature of the surrounding air and lower than 0 ℃, the surface of the heat exchanger will frost. The formation of frost worsens the heat transfer effect of the heat exchanger and increases the resistance of air flow, reducing the heating capacity of the air source heat pump unit, even stopping the unit when it is serious. Defrosting method of air energy heat pump: 1. Frost sensor method: It is used to control defrosting by detecting the thickness of the frost layer. The principle of this method is simple, but it involves high gain signal amplifiers and expensive sensors. As a test method, it is feasible and economical in practical application. 2. Timing control method: as the name implies, defrosting control is carried out according to the preset time. This method is easy to produce unnecessary defrosting action, resulting in unnecessary waste. 3. Maximum average heating capacity method: for a certain atmospheric temperature, there is a unit with corresponding evaporation temperature, at this time, the average heating capacity of the unit is the largest. The defrosting control is carried out with the maximum heating effect produced by the heat pump unit as the goal. This defrosting method has theoretical significance, but it is difficult to implement. 4. Time temperature method: it means that when the defrosting detection element feels that the surface temperature of the heat exchanger fin tube and the heating time of the heat pump unit reach the set value, the defrosting starts. Because the coil temperature is set as a fixed value, this method can not take into account the changes in ambient temperature and humidity, which is easy to cause wrong operation. Moreover, this method is sensitive to the installation position of the temperature sensor.
