17. Is the operation of heat pump unit stable?
The operation is very stable and reliable. The air to water heat pump is specially equipped with high and low pressure protection, winter anti-freezing protection, excessive exhaust temperature protection, excessive outlet temperature protection, insufficient water flow temperature difference protection, water flow switch protection, compressor operation and shutdown delay protection.
18. What are the characteristics of domestic heat pump water heaters?
There are many types of household applicance of air to water heat pump water heaters. It is a new type of household central water heater with high efficiency, safety, environmental protection and superior performance. The main characteristics are as followings:
A. Pressure-bearing water tank design: full water pressure, automatic balance of hot and cold water pressure
B. Separate design: installation is very convenient
C. Microcomputer control: fully automatic operation
D. Any combination of water tank mainframe: to meet personalized needs
19. How to choose the water tank of domestic heat pump water heater?
The water tank of heat pump water heater is determined according to the actual water consumption of the user in a day. Under acceptable conditions, the user is advised to choose as general family:1-2 person, with 100L or 150L water tank (50L/person); 3-4 person, with 200L...
20. What are the advantages of heat pump compared with boilers?
A. thermal efficiency: The annual average thermal efficiency of the product is over 300%, while the thermal efficiency of the boiler will not exceed 100%.
B. Low operating costs: Compared with oil-fired and gas-fired boilers, the annual average energy savings can be 70%. The advantages of low operating costs are increasingly prominent due to lower electricity prices and higher fuel prices.
C. Environmental protection: Heat pump products do not have any combustion emissions. Refrigerant R410A is chosen as environmental protection refrigerant. It has zero pollution to ozone layer and is a better environmental protection product.
D. Safe operation, no duty: Compared with fuel boilers, the operation is absolutely safe, and fully automatic control, no staff on duty, can save personnel costs.
E. Modular installation, easy to add equipment: the product adopts the installation mode of multiple units in parallel, when the user's water consumption increases, the equipment can be added at any time.
